The Earth can't keep up alone environment

I think we don’t really know how important is our world and we don’t respect it enough.
If we continue behaving like that, we won't know where to live in twenty years.

In my opinion it’s really difficult to answer this question, because there are lots of different kinds of people. On the one hand, there are some cultures who really respect the planet, and on the other hand there are lots of people who don’t know what respect is.

So, we haven’t learnt to respect our planet, but we must learnt to keep it safe.
