A proposal under debate in the US Congress to ban the export of electronics waste would likely make a growing global environmental problem even worse, a new study has said.
The researchers call into question conventional thinking that trade bans can prevent "backyard recycling" of electronics waste - primarily old and obsolete computers - in developing countries.
Health Effects of Global Warming
Greenhouse effect causes excessive heat to build up in the earth’s atmosphere causing global warming and affects the environment and health.

"Trade bans will become increasingly irrelevant in solving the problem," said Eric Williams.
Electronics waste is often exported from the United States and other developed nations to regions in China, India, Thailand and less developed countries where recycling is done in a crude fashion.
Global Health Threatened by Multidrug-resistant TB

Sun Cannot Help Us From Global Warming!
A new study has pointed out that the sun cannot put a stop to the rise of global temperatures despite a prolonged period of low activity.

According to the researchers, with the number of junked computers expected to triple in the next 15 years, the problem will grow much worse if an effective remedy is not put in place in the near future.

Reduction of Sulphur Emissions from Ships Will Up Global Warming
A new research has pointed out that reduction of sulphur emissions from ships, will only result in an upward trend of global warming.

Some countries have officially banned e-waste imports, but in some cases, as in China, such legislation has pushed the trade to the black market.
Congress is debating House Resolution 2595, which would ban the export of e-waste from the United States.
"The underlying assumption of this bill and other trade bans is that most e-waste comes from outside developing nations, and that stopping trade with developed countries would cut off the supply of e-waste and stop backyard recycling," Williams said.
But, authors of the Environmental Science and Technology article forecast that the developing world will generate more waste computers than the developed countries as soon as 2017, and that by 2025, the developing world will generate twice the amount of waste computers as what will come from developed nations.
"Rapid economic and population growth in developing countries is driving an increase in computer use in these parts of the world that is outpacing the implementation of modern and environment-friendly recycling systems," Williams said.
"So without action, backyard recycling is certain to increase," he added.
