Disposal of waste
Disposal of waste is one of the most important problems in the world. I think it is very dangerous for our planet and everyone must think about it. In the past, people didn't think about it, but now it becomes very important. If people didn't throw away tons of rubbish, they wouldn't have so many environmental problems now. People started to incinerate waste, but it is bad for nature, so people started to sort the waste. Paper, waste iron must be separate. It is the first problem. If people took as much rubbish as they could to recycling centres, they would protect the environment from pollution. The second problem is the conveyance of waste. If people didn't waste so much paper, if they didn't buy so many packaged things it would also help to reduce the problem. There are many problems with the disposal of waste, but we must find a decision for this.
