"You can say that environment is everything around us. It includes air, water, plants and animals. It´s one of the most important things, despite this it´s destroyed by human activity. We should realize that the Earth is not our property. We are just guests there and we should be thankful for it.

Thanks to many factors (human activity, climate changes…) there are endangered species. For their protection were created wildlife parks, botanic gardens, arboretums or ZOOs. Each of them has pros and cons.
In wildlife parks animal and plants are in their natural habitat, thanks to this they life normally lives, they have instincts and they can born in natural way. On the other hand there is very big problem with poachers, who killed animals for their furs, antlers or ivory. It´s hard to stop them because wildlife parks are situated in big areas.
Zoos are good thing for people, but for animals it isn´t as good thing. They open up exotic animals to people, so you can learn something about them. It´s ideal place where to go with children, because they are in touch with nature. Animals live there in cages and they have no space. I thing that they live boring lives there. They don´t have to fight for food and survival so they lose they natural instincts. However live in ZOO has many advantages. It keeps animals save. Some animal species aren’t able to breed in nature but just in ZOOs.

Greenhouse effect is caused by accumulation of certain gases as in the atmosphere. Those gases are called greenhouse gases and these are: Carbon dioxide, Freon, nitrogen dioxide or methane. Carbon dioxide is produced by burning fossil fuels (coal, oil or natural gas. Freon is from aerosols and fridges. And nitrogen dioxide is contained in exhaust fumes. And the result of their accumulation in the upper part of atmosphere is that they make a layer and stop the heat reflected from the earth’s surface. Due to this temperature is increasing. It causes rising sea levels, melting icebergs and unpredictable weather.
We should try to stop global warming, but it´s not easy, because it´s not only about us. Our factories and cars produce greenhouse gases, but paradox is that the biggest producers of carbon dioxide are herds of cows. It doesn’t mean that we shouldn’t try to stop it. We can replace fossil fuels with alternative forms of energy for example.

The largest rainforests are in the Amazon Basin, in the South-east Asia and in the West Africa. They have a great importance. They absorb carbon dioxide and produce oxygen in process called photosynthesis. That´s the reason why they are often called lungs of Earth. They are habitat for many animal and plant species as well.
Cutting down trees is extremely serious problem. One hundred years ago rainforests were covering about 14% of the world surface; today they cover only 7%.It means that more than 50% of rain forests were ruined during last hundred years.
They are being cut down and burnt, because people need more land for agriculture and more wood for production of paper and furniture.
Due to deforestation many species are under threat with extinction and it causes global warming as well. Another reason why we should protect rain forest is that there are a lot of natural pharmaceuticals. Almost one half of medicines in use come from rain forests.
It´s hard to find solution for this problem, I think. Local farmers need soil. They are pour so they can´t buy expensive fertilizers or agricultural machines. This problem could solve state subsidy."
