1) Because we live in a polluted world. People all over the world discuss environmental protection, but they still continue to pollute air, water and soil.
2) Air pollution, water pollution and soil pollution.
Air pollution is caused by different means of transport in big cities. Water pollution is another dangerous kind of pollution. Factories and plants throw wastes into rivers and lakes making them dirty. Soil pollution stops plants from growing and makes people sick when they eat fruit and vegetables grown on polluted soil.
3) No. İ just throw out the trash. İ used to do it like this.
4) I think goverment should do something.
Many people think that if we have only one language, communication will become easier and there will be no need to learn foreign languages. I cannot agree with them because knowledge of foreign languages makes a person educated and well rounded. You cannot broaden your mind if you see the world only from the perspective of your own culture. Besides, people are a lot more helpful if you speak their language.
In conclusion, I would argue that we should try our best to preserve the linguistic diversity of our planet. I think that larger cultures should have a respect for minority languages, but first of all the younger generation must want to preserve their native language
