The enveronment is everything around us, both natural and made by man. A major problem in the world today is the destruction of the natural environment.
This is complecated problem. We burn fuel and throw away plastic bags these cause pollution . We have made thousands of new chemicals, factories that made or use chemicals always chemical wastes. These are often poesonous, and thay also stay in the environment.
What should we do at school or at home to minimize pollution ? for me, We could pick up garbage littered and put it into a gabage bin, we can reuse bottles and cans, use banana leaves or papers to wrap foot, not throw trash into the water or ground. That is how we can keep the school yard clean and protect the environement.
Moreover, using the public buses can reduce exhaust fume and threefore we can keep the air cleaner.
I think that it is not enough simply to talk about the problem . We must act now before it too late to do anything about it . Join us now to protect the environment. That is how we can save the Earth.
