Помогите! Экзамен в вторник, нужна тема, Our planet is our home. So why are we destroying it

Our planet is our home. So why are we destroying it?

Some people destroy it without even understanding and realizing what they are doing. They don't think about our planet's future, so they do it, unfortunately. Some of us understand all this situation and try to make it better. In the city, where i live, people don't actually throw down anything, for example, to the pavement. So my city is absolutely clear, and people do all the best things that they can do: water plants, plant trees and flowers, etc. Well, i hope all the people in our planet someday will understand how important to keep our planet clear is.

Я надеюсь, что это не слишком мало для тебя, потому что ума не хватило на что-то большее.
