Can someone check these sentences, please? I need to prepare them for Tomorrow.

1) Air pollution is mainly caused by gases from factories and car exhaust fumes. It can cause acid rain, breathing problems and it can increase the risk of cancer.
2)The destruction of the ozone layer is caused by an increase in the amount of carbon dioxide and other gases being released in the atmosphere. The destruction of the ozone layer can be prevented by reducing chemicals from aerosol sprays and fridges and by using alternative energy sources.
3) Water pollution is mainly due to dumping industrial waste in rivers and seas, as well as to dangerous chemicals from factories being poured into streams, rivers and lakes. As a consequence of water pollution, fish die and people have stomack illnesses. We should limit the use of chemicals in industry and fine factories which pollute streams, rivers and lakes.
4) Deforestation is taking place in poor countries (?). They are destroying jungles and forests because farmland is needed to feed their families. Forests are also being burnt or cut down by logging companies for profit.
5) As a consequence of deforastation natural habitats are destroyed and lots of animals are in danger of extinction. Possible solutions are giving (?) financial support to poorer countries or encouraging countries to control the number of trees that are burnt or cut down.
6) Hunting is another problem affecting the natural habitat. Lots of animals and fish are disappering or are endangered. There should be stricter laws and harsher punishments for illegal hunting and fishing and national parks should be more protected.
7) Finally, the production of too much packaging and food waste is dirtying streets and causing a lot of diseases. To solve the problem of litter people should be encouraged to recycle ( to sort their rubbish??)
