Negative effect on Environment
The computer waste and the manufacturing process produce lots of waste .which is harmful to the environment and our society. The used computer or the computer which is in no more use should be donated.There waste produce harmful chemicals which pollute our environment and nature, therefore use of green computer should be applied as it has no adverse effect on environment and can be recycled.
