Как составить рассказ на английском о чистоте природы?

While ever better gadgets make our lives easier, our environment has definitely the reverse situation. The air is full of heavy metals, the seas and rivers consist not only of water, but also of other toxic chemicals right from the factories. And of course, it can’t last this way anymore. We have to make the air cleaner by using all kinds of filters, maybe by using environmentally-friendly sources of energy. And naturally we mustn’t drop litter everywhere and pollute the water bodies.
