Question

What do you understand for Environment problem?

Answer 1

A tradução daquele menino está errada. (Ele provavelmente usou o Google tradutor). A correta é: O que você entende sobre os problemas ambientais?

A minha resposta seria:
Environmental problems are the key to global warming. If we don’t put effort and fight for a better world, our sources and prime materials will slowly decrease. That’s why, for a matter of fact, we should care for our world.
