ted. then we can deal with them sort by sort. we have thought out some methods like storing them in order to change them into plant food, or burning them in a huge stove and use the heat to make electricity. for the first way, the change rate is much too low and it may pollute the under ground water. for the second one, of course it’s wonderful if it’s easy to be tried out. but to build such a huge stove will cost too much. not a good method. now you see, treating waste is not an easy job.
from what has been discussed above, we can do something to our home—the earth. we should make full use of things. at the same time, we’d better reduce its harmful effect as much as possible.
we can do from the basic of waste. that’s to say, we can reduce the production of waste, and reuse and recycle them as much as we can. take material waste for example. nearly all of them can be recycled and reused. and, we should call for using things made o
