Biology Question on Environmental Issues
Evencs refers to a scientific method of treating e-wastes in an environment friendly manner. Recycling of e-wastes in developed countries often involves manual participation and exposes the workers to toxic substances present in e-wastes.

Solution
Irreparable computers and other electronic goods are known as electronic wastes (e-wastes). E-wastes are buried in landfills or incinerated. Over half of the e-wastes generated in the developed world are exported to developing countries, mainly to China, India and Pakistan, where metals like copper, iron, silicon, nickel and gold are recovered during recycling process. Developed countries enforced strict environmental laws in 1980s. This pushed up the cost of handling and treatment of hazardous wastes. They started exporting the wastes to developing countries. Unlike developed countries, which have specifically built facilities for recycling of e-wastes, recycling in developing countries often involves manual participation thus exposing workers to toxic substances present in e-wastes. A scientific method of treating e-wastes in an environment friendly manner has been developed. It is called evencs.
