10. France Tree and lavender fields. By vathiman Apparently, European states account for 14 of the top 20 world's cleanest countries, and France , with its green policy, ranks tenth on this eco list. Climate change is one of the biggest issues for the French government and therefore, various steps have been taken in order to keep the country clean and green. France has ratified the Kyoto Protocol and is committed to reduce its greenhouse gases emission by 5.2% from the 1990 level. In 2004, France closed down its last coal mine, and now gets 80% of its electricity from nuclear power, so CO2 emissions are relatively low. Moreover, the green policy is also reflected in such actions as public system improvement - fast trains, metros, bike programs, introducing taxes on cars, packaging, plastic products, electronic devices, and batteries, suspending GM commercial crops and investing in new energy sources. 9.

Deforestation by burning trees in the Amazon rainforest releases 200 million metric tonnes of gas into the atmosphere every year, according to scientists from Brazilian and US universities. This brings Brazil's total greenhouse gas emissions — including those from burning fossil fuels — to 550 million tonnes, and places Brazil on the list of top ten greenhouse gas emitters worldwide. Deforestation in Brazil's Amazon basin Centro Internacional de Agricultura Tropical (CIAT)/CGIAR Meteorologists from the National Institute for Space Research say that although Brazil's volume of emissions is far smaller than that of the main polluting countries, it is significant because it is not contributing to economic or social development. Scientists estimate that 20 per cent of the four million sq km Amazon rainforest has already been destroyed by development, logging and farming, with 14,754 sq km deforested in 2003 alone. Brazil, the world's fifth largest country, is thought to hav...

It's a mystery why humans and other animals sleep. Leading theories suggest it has to do with memory consolidation or other to benefit other physiological or neural functions. But a new theory holds that sleep is merely a good way to increase an animal's efficiency, by hunting only when the hunting is good, for example, and minimize its risk: The risk of an accident goes down when you're sleeping. Image credit: Stockxpert The purpose of sleep remains one of the greatest unsolved mysteries in science. Although we spend roughly one-third of life asleep, researchers still do not know why. While sleep is often thought to have evolved to play an unknown but vital role inside the body, a new theory now suggests it actually developed as a method to better deal with the outside world. Sleep is often seen as bad for survival. Sleeping animals might be vulnerable to predators and cannot eat, mate, scout for prey, care for relatives or perform other behaviors key to getting by.
