Electronics Recycling
Society’s technological advancements have grown significantly over the years. Electronics devices such as telephones, cell phones, radios, CD and DVD players, televisions, and computers are products that are used in every household. These items are just a few of the many electronic devices that can cause serious environmental damage due to their toxic components. Electronics that are in need of disposal are referred to as e-waste, or electronic waste. Because of the advancement of electronic products, there has been a growing concern about the hazards of electronic waste. Some of these concerns include: improper disposal of toxic materials, health and safety concerns for people disposing of these items, as well as dangers to the soil and water supply. For instance, electronics are made using a considerable amount of toxic substances such as lead, cadmium, aluminum, zinc, copper, and plastics which can all leak poisonous material in the ground and water. These environmental concerns have resulted in the establishment of electronic recycling facilities and industries who take old electronics such as computers for the purpose of recycling and safe disposal.
Electronics containing materials such as metals, plastic, are valuable to the recycling companies. Disposing of electronics through a recycling company will result in fewer electronic devices going into landfills and lower carbon emissions.
Recovering Raw Materials: Recycling electronics involves recovering raw materials from the electronic equipment. Materials such as steel, copper, wires, aluminum, brass, plastics, glass,etc., are extracted and sold to smelters so they can create raw materials. Depending on the type of metal being extracted, they can be processed and used in products required by such businesses as the steel, construction and cement industry. Plastics and wood can be used as fuel to provide heat to industrial furnaces which converts to steam. Metals such as copper are sold to metal refineries.
Plastics: Plastics from such items as computers, computer mice, and keyboards, are sent through shredding processes and machine sorted. They are then sent to other recyclers for further processing.
Larger Electronics: Items such as televisions and computer monitors are dismantled by hand. The leaded glass cathode ray tubes are removed and disposed of safely. Plastics, copper, and circuit boards are removed, separated, and processed.
Hazardous Items: Toxic items are removed from electronic devices and disposed of safely. Toxic substance can include leaded glass, rechargeable batteries, non-rechargeable batteries (i.e.alkaline, lead acid, cell batteries) mercury in lamps and switches, parts containing polychlorinated biphenyls, as well as ink and toner cartridges. The remaining non toxic materials are processed and the recyclable materials are recovered. The materials are shredded and separated according to type. For instance, they can be divided into such materials as steel, copper, aluminum, and plastic.
Refurbished Electronics: There are now many companies that acquire used computers, repair and update them, and resell them at a much lower price. This is a great way to keep electronics out of landfills and make technology more affordable.
Donate Your Computer: If you are getting rid of your old computer because of a recent upgrade, consider donating it to charity. Many schools and non profit organisations are in need of computers. There are companies and businesses that will take your computer, refurbish it, and donate it to a needy cause. Make sure your computer is wiped clean of all information before donating it. Donating your computer helps the community and the environment.
We are fast becoming a technology dependent society. When it comes to protecting and conserving our environment, we have to adapt and change our technological practices to ensure a sustainable future. Recycling electronics is a great way help the planet.
Know that repairing a computer or laptop repair Toronto is not cheap, but it can be cheaper than having to replace the computer. If you run into these situations, you will need to hire a onsite computer repair service Toronto.

Development Vs Tropical Rainforest
I few weeks ago I came across an article about the deforestation situation of all the tropical rainforests. It talked about the main causes this beautiful places, origin to thousands of different life forms, are being damaged by people in so many different ways, among others: subsistence agriculture, colonization, tourism, and civilization development (savetherainforest). This latter caught my attention the most, because last week I went to my teak farm, and I got to see with my own eyes how a highway development affects our rainforest and trees so badly.
My teak farm is located about 1 hour drive from Panama City, it is located in the Colon province, home of Colon City (second biggest city in our country, Panama). Last year the government decided to build a long overdue highway connecting both cities (of course I am all for improving the quality of life of my countrymen) but I can not agree with the amount of deforestation that took place in order to build this highway.
Hundred of acres deforested in order to make way for four lanes that will bring better days to a lot of people, no doubt; but also brought a lot of disorder and chaos to a well established eco system that has being here long before us, and will continue to be here for (hopefully) thousands or millions of years after every single one of us has left this world.
Since development of cities is inevitable, specially today where commerce since to grow exponentially, cities expand rapidly, and the whole world seems to be at everybody s fingertips, we need better way of transport and communication, but could we also be more interested in both preserving and saving tropical rainforests and trees? The answer is a big OF COURSE! I would have loved to see our government promoting the planting of trees in different areas of our country in order to make up for the ones lost during the development of this highway, or during the construction of so many other infrastructures around the country. Also having more people come forward and speak up as energetic and belligerent they are about so many other problems we have on this planet. Maybe all we need are more ways to let people know about this, get them involved.
Since so much rainforest is lost every year, roughly about twice the size of the state of FLORIDA, this has become a problem for every single one of us earthlings, I think we need to get the word out, raise awareness and get people involved! Tropical Rainforest account for only 2% of land surface but through photosynthesis of trees they take massive amounts of CO2 emissions and make air clean and breathable again for every one of us. SO WE ALL NEED OUR RAINFOREST AND MORE TREES!!

Water Extraction in DC

Water Extraction in DC
There are many beautiful and interesting sights in Washington DC, among them are the White House which has been home to every president of the United States ever since 1800; the Tidal Basin Lake famous for its abundant Japanese cherry trees that blooms in Spring; the Lincoln Memorial and Jefferson Memorial, Washington Monument, etc.
But regardless of the beautiful tourist attractions that one could go to in the State of DC, natural calamities in the form of flooding sometimes happen. And when it does, most household residents in DC do the physical cleanup by themselves without hiring water extraction professionals or experts to deal with the situation. Prior to actual removal of water and cleaning, the starting place of the water which caused the flood should be identified as soon as possible and fixed permanently to prevent it from arising all over again.
Cleaning would usually require having to remove all visible waters first by making use of a wet vacuum pump or a bucket – depending on the volume and availability of equipment. The extraction process must be done immediately or as soon as possible to avoid a higher cost of damage inflicted by the dirty waters and also to thwart of any possibility that the area becomes a source of infectious diseases due to the presence of pathogens.
When all the water has already been extracted, floor coverings should be removed immediately and disposed properly. This includes removing items which came in contact with the flood water that are very porous, because the high absorbency rate of such materials has already contaminated the item in question making it very dirty and highly infectious. No amount of cleaning or fixing could reinstate it in its previously clean state; hence replacements should be made eventually if still needed.
Brushing all affected surfaces with a soapy water solution removes the presence of dirt. Pay particular attention to dirt which is inserted within cracks on walls and floors. Rinse the entire area by using a mop and bucket or a garden hose with a spray gadget.
When the rinsing stage has already been done, disinfecting the entire place is a must to remove remaining germ and fungal spores. Remember that disinfecting does not entirely mean total sanitation but a means of making the area or place habitable again. Never mix chlorine bleach with other cleaning products that contain ammonia as this will produce poisonous gas. Before and during application of any disinfectant, make sure to open all air passage ways and vents to avoid inhaling the vapors of the disinfecting agent upon application.
After having done the disinfection phase, the whole area must be thoroughly dried out, and drying usually takes a couple of days or weeks depending on how big the place is and the weather. The re-occupation of any living space which has been previously flooded must only be done once the area is declared by a professional water extraction expert to be absolutely dry. The dryness is tested by a moisture meter which shows the amount of moisture above and below a given area.

Against GM Foods
Posted on June 23rd, 2009 No comments
Against GM Foods
Genetically modified (GM) foods are not being found to be safe for humans, or for the environment. There are a number of reasons why there a growing number of people are against GM foods. Are Genetically Modified Foods Safe? The reason to resist the growth of GM food in our diet is that it has a negative impact on our environment; plants and animals grown organically are not distorting their genetic makeup.
And in the rush to accelerate the production of genetically modified foods, scientists are short cutting testing methods. Recently, the United States Tufts University, School of Medicine was involved in testing the effects of genetically modified rice directly on children (by-passing the usual practice of testing on animals). This direct testing on children created controversy and a formal letter of protest from 22 international scientists to the University; the protest letter has been made public through various social media.
The letter protested the use of children as a breach of medical ethics code since children cannot legally give their consent (since it is not deemed to be informed consent) to participate in experiments. As Professor David Schubert, Salk Institute of Biological Studies said, “…it is completely immoral to feed this rice to children without proper safety testing … [i]t’s like putting a new drug on the market with no toxicology or safety trials”.
In defense of their position, the Golden Rice Organization issued a press release that states they “…us[ed] the correct Chinese and US government approved processes, the trials in China went ahead last year with the formal approval of their parents and the understanding of the children”. How do children understand the impact of genetically modified food on themselves or the environment? It’s a complex subject that many adults have a hard time understanding. Also, how can anyone (parents, children, or testing scientists) understand what the long term effects of genetically modified “golden rice” are on the human body without prior study or testing?
More importantly, will the overall risks of genetically modified foods over time out weigh the alleged benefits? Farmers have cross-bred plants and animals for hundreds of years to improve their products. Improvements to size, produce yield, taste, hardiness have been achieved through relatively natural means and within nature’s own boundaries; different species were not bred together.
With the discovery of DNA and a method of gene extraction, the concept of genetic modification was born. The intent of genetic modification is to create food that grows quickly, yields much, is resistant to pests, to disease, and to other natural events. However a number of scientists respond that the benefits are not worth the risks; genetically modified foods often become resistant to herbicides and pesticides requiring ever increasing amounts. There is the suspicion (still unproven) that pollinating bees have been affected by the increasing use of these chemicals and that both pollinator and predator species have been affected by the genetically modified crops (also known as transgenic crops) through habitat destruction and use of dangerous herbicides and pesticides.
Since the introduction of genetically modified foods, some scientists are reporting that food-related illness has increased. The only published human feeding study confirmed that genetic material in genetically modified soy transferred into the DNA of intestinal bacteria and continued to function. What long term impact will these foods have on the population and the environment? There are many more potential risks in the development of genetically modified foods. Animals that were fed genetically modified feed appeared to suffer from increases in fetal death, low birth weight, sterility, and more. The concern is that human reproductive failure and sterility or infertility will be long term consequences to using GM foods.
In the US, the Department of Agriculture reports that cotton and corn crops have been genetically modified to produce their own Bt toxins since 1996. Bt modified crops are insecticidal crystal proteins and are considered effective against crop-damaging caterpillars. The toxins are considered important for pest control and since resistance to herbicides and pesticides is growing, the sentiment is that these genetically engineered Bt toxins will help to protect the crops. The issue with the GM Bt toxins is that they are considered serious allergens; ever wonder why so many more children and adults are exhibiting allergic reactions than ever before?
The problem with genetically modified foods is that there is also a reaction for the action; unfortunately, globally, in our rush to grow food supplies, we have not taken the time to properly test and research the long term impacts and effects of genetically modified foods. It is easy to be against GM foods - our planet is at risk.

Saving Money and the Environment, One Bag at a Time

Saving Money and the Environment, One Bag at a Time
With the current economic problems, hopefully more people are interested in saving money and recycling. Businesses are always interested in keeping the customers they have and getting new ones.
The cost of fuel has been big in the news for years but, when compared to plastics, it’s a small percentage of petrochemical use. Saving on the use of petrochemicals for making plastics can extend the timeframe before peak oil and lower the price of fuels.
Most grocery stores offer a five cent per bag discount if you bring in your bags. You can do that in a variety of ways. One is by taking the old plastic bags back and another is using cloth bags, which can often be purchased at the store. Usually, grocers will sell cloth bags with their advertising on them at their cost, which is cheaper than an equivalent type bag can be purchased elsewhere. By doing that, the grocer gets their investment back and advertisement as well. If your grocer doesn’t have a program of that type, tell them about the advertising value and mention that you take your bags everywhere, including their competitor’s store.
If you don’t want to spend the money on cloth bags, reuse your old plastic ones. Plastic bags aren’t as durable as cloth and it’s a good practice to double bag when using a plastic bag more than once or twice.
We’ve found cloth bags to be a good investment. Most of our bags are almost twenty years old. If we save two cents a bag and buy ten bags of groceries, and do that five times a month, we’ve saved a dollar a month. That doesn’t sound like much but our cloth bags paid for themselves the first year, with the last eighteen plus years being pure savings.
Tying the bags off keeps the goods inside from spilling all over the trunk on the way home. But, tying them off presents another problem. Getting them untied, especially the plastic bags, can be difficult if not impossible. Most people consider it not worth the effort and rip them apart. There’s a simple answer to that problem. Since a picture is worth a thousand words, I have a brief slide show that explains the process. Once the bags are tied in the manner I show in the pictures, they untie easily and can be used over and over.
Since a picture is worth a thousand words, I have put together a slide show tutorial. You can access the slide show by going to the URL in the resource box.

USA – China – A G2 For Climate and Economy?

USA – China – A G2 For Climate and Economy?
China appears to view global warming as an economic issue, Obama’s administration is primarily focused on the current economic crisis as well, but climate change is also a serious crisis and a threat to the world’s economic system itself with all its present and predicted impacts. Don’t these global problems require an integrated economic and environmental strategy? The hypothesized summit between Barack Obama and the Chinese president, Hu Jintao, could be an important step to accelerate urgent actions needed both to face the global economic downturn and to build a solid climate pact.
China, in its last 5-year plan, sets targets to reduce national energy intensity (energy used per unit of GDP) by 20% between 2006 and the end of 2010. According to Deborah Seligsohn, China Program Director on Climate, Energy and Pollution of the World Resources Institute, this target seems to be realizable given their latest remarkable record (-1.8% in 2006, -3.7% in 2007, and -4.2% in 2008.) Last month Hillary Clinton met experts from the Asia Society and the Pew Centre for Climate Change that together wrote a report that could help the creation of this US-Chinese partnership on climate change. But the good examples from China, although not directly referred to CO2 emissions, and Obama’s ambitious plan on energy and climate will need decisions from other 13 countries (or federations such as the EU), including Russia, India, Japan to get 80% of world’s emissions “under control”. Nowadays the other 173 countries account for about 20% of total CO2 emissions, but population increase and old development patterns could dangerously increase their “pollution share” in the future: every nation will be then required to cut the CO2, but large amount of money are needed to do so. Where will our leaders take Dollars, Yuan or Euros these days?
Next steps: -264 days to COP15:
Two events along the path to Copenhagen will take place in Bonn from March 29th to April 8th: the 7th session of the AWG-KP (Ad Hoc Working Group on Further Commitments for Annex 1Parties under the Kyoto Protocol) and 5th session of the AWG-LCA (Ad Hoc Working Group on Long-term Cooperative Action under the Convention). As we can read on the UNFCCC website “this is the first of three planned negotiating sessions before COP 15 in December” and can hopefully prepare a good ground for delegations and political leaders to decide upon.Written by Luca Marazzi on behalf of Responding to Climate Change.

How to Report Greenhouse Gases (GHGs) – A Summary of the Pending GHG Regulations
Posted on June 18th, 2009 No comments
How to Report Greenhouse Gases (GHGs) – A Summary of the Pending GHG Regulations
The newly formed Obama administration has listed greenhouse gas (GHG) tracking and reporting as a major goal, with the objective of protecting the future of the environment by reducing today’s carbon footprint. If no action were taken, the makeup of the earth would significantly altered. Future actions will establish a market drive carbon cap and trade program to drive GHG emissions reductions.
Greenhouse Gas tracking is outlined in The Climate Registry Protocol, which details the requirements for mandatory monitoring and tracking. The premise around greenhouse gas tracking are included in the U.S. Clean Air Act, aimed at improving air quality and lowering greenhouse gas emissions.
The Environmental Protection Agency (EPA) proposes mandatory reporting of the gases contributing to global climate change from about 13,000 facilities nationwide. These facilities account for the majority of greenhouse gas emissions within the United States and present a logical starting point for emissions reductions in the US. The regulation would cover companies that either release large amounts of greenhouse gases (GHG) directly or produce or import fuels and chemicals that when burned emit large amounts of carbon (CO2) gases.
One of the major focuses of the Greenhouse Gas tracking protocol is refrigerant gases used in refrigeration and cooling systems by numerous facilities, including manufacturers, food processors, retailers, grocery stores, office buildings, municipalities and hospitals, just to name a few. Because of their chemical makeup, refrigerant gases contain significant levels of carbon in the form of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and perfluorocarbons (PFCs). Use of these compounds has been regulated under the U.S. Clean Air Act for several years.
Greenhouse gases absorb and release radiation into the atmosphere, setting off a global warming effect on earth. The intent and overall goal of GHG tracking relates to better collection and management of the emissions data now so informed decisions can be made about future carbon trading schemes. The tracking protocols also help government entities to more accurately inventory the amounts of emissions reaching the atmosphere. The new GHG legislation puts in motion the data collection, organization, and first stage reporting mechanisms to allow the US to accurately calculate and maintain a GHG emissions baseline across the entire economy. This will allow for better understanding today as well as to determine progress for future Cap and Trade programs. With this accurate information, it can be determined if the guidelines are effective in lowering the harmful effects of these substances to the ozone layer.
Greenhouse Gas tracking involves measuring direct and indirect emissions and keeping extensive records on its usage, maintenance, leak containment and disposal. Heating and cooling systems, as well as other energy consumption, are defined as direct emissions.
Better and more effective GHG management is an objective of the current US government. No longer will the US sit by and watch the world attack the issue of climate change. The US is now taking action to lower carbon emissions to the betterment of future generations. By taking no action, the earth’s makeup would significantly change, with humans and animals adversely affected and marine and plant life severely damaged.
Greenhouse Gas (GHG) management and reporting is now falling under the EPA regulations contained within The U.S. Clean Air Act because the causes of global climate change is now well know. Human activities and the use of global warming substances, like refrigerant gases, are all leading to increased global warming. The substances are carbon dioxide, chlorine, bromine, nitrous oxide, chloroflurocarbons, hydrofluorocarbons, methane, methyl bromide, methyl chloroform, sulfur hexafluoride, hydroxyl, perfluorocarbobs, halons, carbon tetrachloride, fluorine, and the fluorinated gases hydrofluorinated ethers and nitrogen trifluoride. The mandatory law is aimed at reducing the use of these substances to lower the effects of global warming.
Beginning in 2010, GHG management, tracking, and reporting will be environmental law for the highest emitting facilities. Part of the management will revolve around better tracking and reporting of refrigerant gases. Entities must submit usage reports and service records for all refrigerants having high GWP. Special calculations are applied to refrigerants when any leads occur. The GHG emission reporting rules and related protocols allow for progressive companies to take advantage of software already created to help with carbon emissions reporting. Some web applications allow organizations to track GHGs to the asset level across global, distributed facilities.
Software provided by Verisae tracks carbon dioxide (CO2) gas emissions according to The Climate Registry protocols across all sites so companies can manage their carbon emissions and work towards reducing their carbon footprint.

A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chainThe Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.
Steve Bynum has worked at Palmer Station along the Antarctic Peninsula. He not only enjoyed the ecosystem along the Bellinghausen Sea but he has also witnessed the changing climate conditions.

The Canada Pine Beetle
Posted on June 17th, 2009 No comments
The Canada Pine Beetle
For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.
These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees.
During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.
Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction. Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.
The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.

Green Driving Tips
Are you trying to make changes in your lifestyle that will help to preserve some of the natural resources being used everyday? There are many things that individuals can do to make a difference. However, one of the biggest concerns is the problems caused by all the vehicles being driven today. Everyone knows that vehicles put out gas emissions that add to the amount of air pollution already causing problems for humanity. But what can you do?
Very few people can do without some sort of vehicle in today’s society. It would be almost impossible to get from one location to another without driving most of the time. Still, it’s important to do all you can to reduce the amount of pollution being emitted into the air. Since buying a hybrid is not an option that everyone can take advantage of, here are a few tips for driving green that will help reduce pollution caused by vehicles.
• Proper Maintenance – One of the best things that you can do to make sure you’re driving green is to keep the maintenance up on your vehicle. Keep it tuned up, air filters changed and make sure the tires are inflated properly.
• Carpool When Possible – It may not always be possible to carpool but do so whenever you can. This will make more of a difference than you might think.
• Plan Your Trips: If you plan your trips in advance you can cut down on your driving time. You can plan the shortest route that will accomplish everything you need to get done. Stop by the store on your way home from work instead of going home first and leaving again. Anything that reduces your driving time will help.
• Walk More – When you’re visiting a neighbor, going to the local park or anywhere that is near your home, try walking whenever it’s practical to do so.
• Cut Down on the AC – Only use the air conditioning whenever it’s absolutely necessary. You can roll down the windows other times to let a breeze blow through.
• Drive Smart – Driving smart includes avoiding sudden stops and starts and driving the speed limit. Speeding uses more gasoline and produces more pollution than necessary.
These are all simple and easy things that everyone can do to help the environment. If every driver were to make these changes it would make a huge difference in the amount of pollution created each day.
