Nowadays, our planet had a lot of environmental problems and for humanity it is very important to solve them. Some people believe that ecology affects on animals. As for me, I agree with that opinion and think that animal`s health depends on the state of environment. To begin with, all oceans are polluted with rubbish and sea creatures suffer from that. For example, turtles think that litter it is a food and swallow it. As a result, a lot of turtles die because of plastic in their stomachs. Secondly, main problem of environment today is global warming. Animals that live on the North Pole suffering from global warming. Polar bears are losing their weight, because ice is melting and they could not hunt on seals. However, there is another point of view. Some people strongly believe that global warming affects specific animals only and other environmental problems also not so serious. Nevertheless, I can not agree with that statement. All problems of ecology are important, because they affects on animals habitat. A lot of animals will die because they are not used to warm conditions. Scientists found out that some animals have died out already because of global warming. In conclusion, I think that environmental problems are very harmful for animals and all people should help to solve them, because only together we can save our planet.
