I noted a few errors below. Hope this helps!
People live under the pressure of various problems social, ecological, economical and others.
People live under the pressure of various social, ecological, economic problems.
I don't mind national kitchen when I go to this or that country.
I don't really understand this sentence. Are you saying that you don't mind different kinds of food?
I'm not sure exactly what your essay prompt is, but perhaps to improve your essay you can reorganise it according to points. You have sports and food, which are great. However, your point about sports follows the elaboration of pollution, thus making the paragraph disconnected. If you can neaten the essay by putting different ideas in different paragraph, it would be easier for readers to read and appreciate your essay.
All the best for this essay!
