Animal testing

Animal testing refers to the use of non-human animals in scientific experimentation. It is estimated that 50 to 100 million vertebrate animals worldwide — from zebrafish to non-human primates — are used annually. Although much larger numbers of invertebrates are used and the use of flies and worms as model organisms is very important, experiments on invertebrates are largely unregulated and not included in statistics. Most animals are euthanized after being used in an experiment. Approximately 10 to 20 percent of the animals are used for safety testing of cosmetics or chemical products. More...

Acid Rain

Acid precipitation, more commonly known as acid rain, is rain that has been contaminated by air pollution. It is, therefore, more acidic than normal rain. More...

The Science and Technology section at copperwiki focuses on the ways innovations can be conducted and applied to meet human needs while preserving the life support systems of the planet.

With science and technology are we creating abundance, or an ecological crisis? Do advanced technologies make us more secure, or escalate dangers? Find answers to many such questions through our well researched articles.

This section deals extensively with developments which ensure that in our efforts to fulfill our needs we do not compromise with the needs of the future generations. Our articles dwell on the choices we make to use technology to shape our world and share concerns about our choices.

It is an ideal platform for sharing visions among conscious living individuals for creating an improved quality of life in ourselves, our community and our world.

Methane

• Methane is a very powerful greenhouse gas because it can retain 21 times more heat than CO₂.
• There's 400 gigatons of methane locked in the frozen arctic tundra.
• Ice-like structures called clathrates contain 3,000 times as much methane as is in the atmosphere.
• A temperature increase of merely a few degrees would cause these gases to volatilize and "burp" into the atmosphere, which would further raise temperatures, which would release yet more methane, heating the Earth and seas further.
• The Earth is heating more rapidly than it has at any other time during the past 10,000 years.
• Even if emissions of greenhouse gases were to stop immediately, earlier emissions would continue to affect climate for centuries to come.More ...
