A Short Presentation in English Class

Dear professor and hello classmates,
Beside In addition to family, friends, health & hobbies it is important for to me, that we try to use only as much reserves of the Earth, as necessary. Recently I saw an interesting documentation  documentary about Jane Goodall, the famous women woman who carefully watched observed chimpanzees in their natural living area habitat in Africa, exactly in the Gombe Stream National Park. Jane Goodall requests us to live in a friendly way with other human beings, animals and of course the nature.
When rainforests are cut down (which happens every hour is done constantly) this interferes into it affects the balance of the earth's ecosystem ecosystem of the earth. Because when there are no rain forests anymore, they can’t produce oxygen and clean the air. When there are no rainforests left, the production of oxygen is interfered and the air will become highly polluted. But not only this could happen. The water cycle and the climate can be affected too. And of course some animal or plant species might become extinct. And do you know that one out of four ingredients in our medicine is produced from rainforest plants? Some of these plants may help to heal and to deal with some deadly diseases.
But what particularly can we, as individuals, do for- here as an example- the chimps in Tanzania, to help to keep their living areas?
One point is that mobile phones include 60 different, useful, raw materials. Most of them are won mined African rainforests  rain forests in Africa. So the jungles get destroyed and with them, also additionally many wild animals, plants and native people lose their homes. If you want to help the Earth environment through this , there are some projects, where you can donate your mobile phone to be recycled.
Another thing is that Subsequently, many animals are brought imported to our country illegally, e.g. parrots. So obviously we shouldn't buy these animals, because if we do this, more and more are flown brought in.
We can also help to protect the rainforests by using locally produced food, wood and not drinking much coffee. It would also be better Also buying things, which are made out of regional wood, instead of rubber, would be better for the environment. We all should think about what we are purchasing buying, recycle things and use them two several times instead of once one. Supporting programs that which help to preserve the rainforests, is also not a bad an excellent way to do a little thing for the whole world.

Sorry that i modified that much, I just tried to make it sound more smooth and more fluent :)
