I think, that people must protect our planet from the main problems of economic. Because it is very important to understand, that nobody can live wothout oxygen,Cause that is absolutely impossible! Almost every day we can notice this kind of people, who can not get the simpliest rules of  keeping health life routine. The main problem of economic is cutting the trees! Thanks to it., we can breath, but the bad news, in our wide world, there is a little amount of plants. Well, I guess we should think about it because it is rather important than the money.

My best friend is Petya!

Petya is a smart, loyal and honest friend.

He has brown eyes and brown hair, he is of medium build, but at the same time, he is very hardy.

Petya and I go to the cafeteria together, play during recess at school, and also go home after class together because we are on our way:)

Petya is always in a good mood, he is the most cheerful person on earth! He will always help in a difficult situation, support me when I feel bad, I know that he will never leave me, and I will never leave him!

Petya is the best person I've ever met.
