Global warming, fiction, the dispute is nearing an end as environmental health scientist narrow the data down to scientific evidence, and, whichever side prevails, this data will give humanity the information we need to exercise some control over earth and our own destiny.

When former president George W. Bush’s administration called into question the validity of global warming, the science community, with few exceptions, angrily revolted as scientist do, with contempt, disparagement, and vindictive, no doubt, rightfully so, pointing out that his so-called leader had barely managed to graduate from college (how well he understood the influence of power and money though!), was recognized as nearly illiterate, and had dared not read a book over five hundred pages, and so was unlikely to render a believable conclusion on anything scientific, perhaps on anything at all that required disciplined thought. While this interference with science did boggle the progress the rest of the world was attempting to achieve through emission control treaties, as predicted, this irresponsible, perhaps even selfish meddling with the fate of humanity has been brought-–like most of the other influences of Bush’s presidency—-into the clear light of sober refection and shown to be pure foolishness.

Thirty years before Bush proposed his myopic vision of the perils facing the earth through global warming, a much more esteemed thinker, the chemist, Charles F. Baes , Jr. of Oak Ridge National Laboratory, a U.S. Department of Energy institution, sounded the alarm, pointing to the rising Leviathan of global warning, the reality of the greenhouse effect, and the unconsciousness of man to the coming disaster that would follow as effect. No self-respecting scientist today denies that the activities of humans, from the burning of fossil fuels to deforestation, are significant, contributory causes of global warming and the deterioration of environmental health. New data is revealing the intricate relationship between human activities and the biosphere, but common sense tells us that if a man sets a forest on fire and burns it down, carbon dioxide is increased in the atmosphere, ecosystems are destroyed, animals of every variety are killed, and, at least in that former forest, the micro-climate is altered. Now, in addition to common sense, the light of science breaks through the black clouds that dark men, for reasons of power and profit, have breathed over our cherished earth. Science continues to bring us out of ignorance and the arrogance of selfish men.

Today, and for the last ten years, our scientist are experimenting with grasslands and forests, measuring carbon dioxide levels, temperatures, precipitation, and actually varying these in order to determine the responses of life forms and ecosystems. With this data, we will be able to establish environmental health boundaries and requirements, to predict possible dangers, and enact measures to control and restore the damage our activities have done. Using scientific method, using theory, experiment, observation, reason, and results, our environmental health scientist are providing us with something we should never look to political forces to disclose: science is revealing the truth, the truth about our affects on the earth, on life, from the worm to the lark, on the generations of humans that will come after us, and on our responsibilities to all of these. Thanks science!

Bees - there aren’t very many cities in the land where beekeeping is against the law. But New York City is one of those places that are strictly intolerant of bees. But these bee control laws never really worked very well for the thirty years or so that they have been in place. Bee-friendly citizens have always known that the authorities were just on a witchhunt trying to outlaw the raising of all kinds of bees - harmless or harmful. What sense is it , they ask, for the law to club non-dangerous, even harmless varieties of honeybees together with dangerous creatures - and to ban them as other insects like tarantulas. As the rebels for years quietly raised their bees in their little personal beehives, in a private secluded spot in their homes, they always risked being caught by the authorities, or being turned in by neighbors; the $2000 fine that the offense came with, was something they were willing to deal with.

But you know what - their patience has finally won the day; they’ve been petitioning the City board in charge of the honeybee ban to reconsider their rather strict view on the matter. And the City has agreed that the keeping of the common gentle variety of the honeybee called Apis mellifera doesn’t really call for all this fuss; especially in view of the fact that bees control is not the problem it used to be. North America is beginning to see an alarming disappearance of the honeybee, and repopulation may be more appropriate today than bees control.

But in some places, even bee lovers have some trouble with the aggressive bee varieties, and call for their control. Typically, beehive removal can be something you could do yourself, sort of a DIY project around the house. As scary as the prospect seems, if you follow the rules, you really could get it done, and without too much risk to yourself. You would only need a professional exterminating company, if you have a spectacular infestation problem. The basic gear you need, to get started, are a face mask worn together with a scarf for the lower part of the face, a large sun hat, swimming goggles around the eyes, heavy gloves for the hands, a thick full-sleeved shirt and heavy pants that can be packed into a good pair of shin-high boots.

Your bees control tools will include bee spray with Pyrethroids, large shears, a matchbox, and a large broom, all of which you can find at any gardening store. Now for the real hard work the safest time to approach an angry bees nest would be at night, when they have calm down after a day’s work. Make sure that you carry a flashlight that has been covered over in red plastic sheeting, to produce a red light. Bees can’t see red light, even if you can. Stand at a reasonable distance, and use that bee insecticide you bought, to spray the nest.

Taking advantage of all the commotion this action causes in the nest, spray the poison, the insecticide, inside the nest, and run away to protect yourself. It will take about an hour for the poison to work properly. You could return to spray it again, if it doesn’t seem to be finishing them off in that time. All that remains then, is cutting the nest off with your shears, and putting it in a barrel to burn. When bees scout for a site to build their hive, they usually like places that show signs of an old hive. It probably makes them feel that there is something good about that location, if the earlier bees went to all the trouble of building a hive there. So, to prevent future infestations, you’ll need to scrape the branch or whatever it was that the hive hung off - to make sure you don’t get return visitors. Remember, bees control is only a DIY project, if it is just a single, small hive. And don’t forget to wash off any hint of perfume or cologne before you roll up (or rather roll down) your sleeves to get to work. The bees just love cologne.

Going green is all the rage these days, as more and more people come to understand the importance of taking care of the environment. Although recycling is a terrific start, we need to go much farther than that if we want to start repairing all the damage that has already been done. That’s why in addition to the traditional “Reduce, Reuse, Recycle” mantra, we should make a concerted effort to buy eco friendly products and reward manufacturers who adopt this responsible approach.

There used to be a time when choosing eco friendly products meant sacrificing choice or quality, but thankfully that’s not the case anymore. So many companies have jumped onto the green bandwagon that consumers have a wider array of choices than ever before. In fact, you can find eco friendly products for just about every avenue of your life, from automobiles to kitchen appliances and even entire homes.

Hybrid vehicles lead the pack of eco friendly products that can have an immediate and positive impact on our world. Cars such as the Toyota Prius and Honda Insight both reduce fuel usage and cut down on harmful emissions, which makes a powerful one-two punch for the environment. While lots of folks would probably love to drive hybrids such as these, not everyone has the $22,000 necessary to purchase the entry-level models. Fortunately, there are a bunch of other eco friendly products that are much easier on your wallet.

Take clothing, for instance. Conventional clothing that is made from fabrics such as cotton put a tremendous burden on the world’s water supply, as it takes a lot of water to keep cotton fields irrigated. Moreover, most growers use pesticides and other harmful chemicals to protect their crops. These chemicals can then seep into the soil or groundwater, causing even more damage. Conversely, clothing manufacturers that produce eco friendly products use such materials as hemp, bamboo, soy, and other sustainable textiles. The production of these materials does not take the same toll on the Earth, and has the added benefit of providing much-needed agricultural jobs to people in developing countries.

Other eco friendly products that you can incorporate into your daily life include reusable shopping bags, organic soaps and cleaning agents, kitchen disposables (such as paper towels, plastic wrap, and sandwich bags) made of recycled materials, self-charging flashlights and portable radios, and rechargeable batteries. This list contains just a fraction of the growing selection of green goods available, so don’t limit yourself to what you see here.

Doing your part for the environment doesn’t mean you have to sacrifice your comfortable lifestyle. By making a few small changes like buying eco friendly products whenever possible, you’ll be making a bigger contribution than you think!

If development continues at the pace that we are going right now, we are sure that the environment will be destroyed. The global warming is already affecting certain areas of the world. For example, there are more and more cyclones in some parts of the world and what is even worse is that they are gaining intensity. Indeed, it has become increasingly important that every one of us join hands in order to combat global warming. It is important that we focus more on renewable energy nowadays. There should be more emphasis on sustainable development. Energy such as solar and wind should be encouraged. One French article that I have read recently is ‘energie solaire’ and should help you to learn more on how we can save energy. See also: gardening organic vegetable

While we are using up fossil fuel energy sources faster than more reserves can be uncovered, it is only reasonable to start turning to one of the most abundant energy sources at hand that is free-solar power. It is an alternative energy resource that still hasn’t been fully appreciated by a great many other countries which makes it very viable for the future. You can generate this energy when you build a solar array you install on your roof so it can capture as many solar rays as possible and then convert them into electricity. You can plan on using 10 to 12 solar panels to generate a kilowatt of power. Check out build a solar array for more help with setting up your home-built solar array.

Conventionally, electricity is produced by moving colossal turbines. These turbines are moved with the help of various types of energy. Let’s look at the most conventional ways of producing electrical energy:

•  By using various fuels and water
• By nuclear fission
• By bio-waste
• By hydro-power
• By wind

Why is there a need for looking for alternate electricity sources?Alternate power solutions are needed in the light of highly-depleting fuels and energy sources. Moreover, most of the convention ways of electricity production harms the environment in one way or the other.

The world is currently faced with tremendous power-crisis. We can no longer depend on fossil fuels for power. At the same time, we need to take measures to prevent the harmful effects that convention power production has on the environment.

Feel free to visit our home alternative energy website: you’ll be able to read more detailed articles about how electricity is produced and about ways to produce it by yourself with very simple equipment.

Once you have a quality manual and you have learned how to make solar panels, the supplies are fairly simple to find.

Most can be found at your local hardware store like, plywood, sheets of glass, and a roll of copper wire.  It is also easy to locate inexpensive solar or photovoltaic cells to use in your project.  Many are available over the Internet or you may have a retailer available locally.

One you’ve learned how to make solar panels and you have your supplies, it usually takes about a day to assemble a 100-watt panel.  This is the perfect amount of electricity to operate small appliances or a small workshop.

The most important step is finding a quality manual with detailed instructions for learning how to make solar panels.  In many cases you get what you pay for, so don’t be afraid to spend a few extra dollars on a well-reviewed instruction manual.  Overall, the cost of the making your own panels is so low, the price of the how to guide is minimal-you will still be paying way less learning how to make solar panels on your own than purchasing a professionally installed system.

With a little bit effort, you can be on your way to learning how to make solar panels to meet your home energy needs.  Then sit back and bask in the pride the next time the power goes out on your block.  Your lights will still be on because you learned how to make solar panels and your energy supply is still in your battery bank.

Few subjects arouse more controversy and argument than the subject of nuclear power. There has been both strong opposition, as well as defenders of this technology. The finite nature of fossil fuels is focusing the minds of politicians on whether to build new plants.

Supporters of nuclear power say that the absence of greenhouse gas emissions is justification for building more nuclear power plant facilities. Environmental campaigners point to a number of concerns. There have been accidents,  radioactive leaks, and now the threat of terrorism at nuclear facilities. Radioactive waste is another problem, with regard to how to transport it and how to dispose of it safely. Cost is also a factor in the debate.

So what is the answer? Clearly, there are issues to be addressed to increase the safety of using nuclear power plants for commercial and residential power sources.

It seems that all the ecological campaigns are now bearing their fruits. There are many people that are now prepared to take action in order to save the planet. Various measures are now taken to fight against global warming. The biggest challenge lies in the fact that we should look for cleaner alternatives for fossil fuels. Indeed the biggest agent of pollution is the exhaust fumes from our cars and factories. In order to find cleaner energy sources more and more countries are investing into the development of green energy sources such as hydro-electric. If you want to learn more on all the energy sources that are available this French article ‘Énergies renouvelables’ should really interest you. See also: Benefits of eating organically

Little things add up to alot.  In your efforts to go green look at replacing your paper appointment book with appointment book software.  Anytime you can help reduce the number of trees cut down for paper, you are helping the environment.

There are many different kinds of trees in the world, but for gardening, fast growing trees are the perfect choice. These trees usually reach maturity in about 5 years on average. People love to plant fast growing trees in their garden because these trees quickly put up a screen between their backyard and the outside world, as well as delivering much needed shade.

Besides that, all trees serve useful functions as far as carbon sequestering, and ecological balance, are considered. Trees that grow fast will normally have a higher intake of carbon dioxide, as opposed to slower growing trees. Thus, the more fast growing trees are planted, the better it is for the environment and climate change in general. These trees also serve as habitat for many kinds of garden inhabitants, playing an important role in the health and ecology of your garden.

Fast growing trees grow up fast, and die fairly fast. Their wood is often not very durable, because it has not been formed over a lengthy period. Nonetheless, these trees are still capable of reaching grander dimensions, if cared for properly. If you want to plant some fast growing trees in your yard, some species could be saw tooth oak, acacia (for hotter climates), and maple.

In order to develop a solar power system for the home, the amount of power needed will have to be calculated, based on the number of items being plugged in, how often they are used as well as the watts they require to operate.

A solar panel can be connected to others that can produce enough power to operate everything connected to the system, as well as provide power to charge batteries for when the sun goes down.

With a properly configured system, energy created by the solar panel can provide continuous power to the device, provided the sun is shining. Once the sun goes down, or is blocked by heavy clouds, the system can be configured to automatically switch to the battery. However, once the battery goes dead, there will be no more power until the sun comes back up.

Typically, the number and size of the batteries can be installed to power most of the important appliances while the sun is not shining and is especially useful in areas that are off the electric grid.

Remote camp sites and cabins, usually have few power requirements, and are idea for small solar panel systems.

As research continues on the viability of using the sun to provide electricity, new technologies in designing the solar panel are continuing to reduce their cost as well as their portability, making them more efficient and offering a better value.

All photovoltaic cells, which convert energy from the sun into electricity are housed in what is termed a solar panel and depending on the size of the panel and the number of cells they contain, power can be produced to energize a whole house to several houses connected to the solar power system.

When the solar panel was first introduced, its uses were limited due to the output limitations. There are many examples of solar powered devices, such as small calculators that operate by being in bright light.

However, most of the early devices powered by a solar panel were small with very limited power needs.

Converted solar energy is pulled from the panels at 12-volt direct current, while the vast majority of household appliances require 110 volts of alternating current.

To provide power for household use, the solar panel sends energy into a storage battery, similar to the one in cars, and then through a power inverter that converts the 12 volts into 110 volts, able to power household items such as lights and virtually everything else that plugs into a wall socket in the house.

A diesel engine will go much farther on a gallon of fuel that the standard gasoline engine because of their designs, and due to the higher energy density of a gallon of diesel fuel. But, it also takes a bit more oil to manufacture a gallon of diesel than a gallon of gas, with the production and refining processes for diesel producing more gases that trap heat. Therefore, when you consider the relative merits of deisel and gas cars, try knocking the MPG estimates for the diesel car down by 20 percent. A diesel vehicle will cost you a bit more, so you’ll get more bang for your buck from a gasoline vehicle. Diesel vehicles also emit more particulate matter and NOx, both of which are serious health hazards and air pollutants. Current diesel engines are more polluting per each mile they are driven than gas engines. If biodiesel is available in your area, you’ll still need to examine whether a diesel is the right vehicle for you. Read also: Construction Equipment and Heavy Equipment

We get most of our energy from the sun and refer to this energy as solar energy. Solar energy is advantageous for a number of reasons, namely because it is a renewable source, meaning that it will never run out, at least not until there is no more sunlight, and also because it does not produce any air or water waste as its counterparts do.

A solar collector is the most common device used to collect heat from the sun, and works by allowing the sunlight inside the material, absorbing the sunlight and changing it into heat, and trapping the heat inside. Solar space heating is a term which refers to using solar energy to heat the inside of a building, and passive solar homes are those in which the entire house is actually acting as a sort of solar collector.

There are a variety of different ways in which this solar energy can be used, and namely it is used to heat water and air. Water heating is considered as being the second leading home energy expense, and so by switching from your present energy source to solar energy, you will be saving yourself a great deal of money. Depending on where you live and how much water you use on average, your solar water heater could be paid off in as little as five years.

Solar energy is also used for electricity, and there are two ways to generate electricity from solar energy, one involving photovoltaics and the other solar thermal systems. Photovoltaic or PV cells are made of two thin slices of silicon sandwiched together and attached to metal wires, and once the two layers are placed together, an electric field is produced that prevents the electrons from traveling from the top layer to the bottom layer.

Solar thermal systems can be used in place of these PV cells, and most solar thermal systems use solar collectors with mirrored surfaces in order to concentrate sunlight onto a receiver that heats a liquid. These systems are typically one of three types: central receiver, dish or trough.

You’ll find some facts, suggestions, and tips for creating your own organic vegetable garden.

What makes a garden organic?

Most gardeners describe organic gardening as simply rejecting the use of anything chemical or artificial to control insects or to fertilize plants. Add organic fertilizer and soil conditioning material at least three weeks before you plant seeds or seedlings. It takes that long for organic material to start working in the soil. Organic materials are the foundation of organic gardening
Professor Stephens at the University of Florida suggests the following list of organic materials: animal or plant manures, compost, cover crops, or mixed organic fertilizers. Controlling damaging insects and diseases the natural way. Keep your garden clean and refuse-free. Handpick insects off your plants. Don’t let weeds steal your plant’s thunder (or their nutrients)

Keeping your garden’s soil cultivated will keep weeds small, making them easier to control. If left to take over, weeds will steal the nutrients from your vegetable plants, leaving them more prone to diseases. Read more in French at: Vivre bio and Produit biologique
