Global warming. Who caused it? It's us, humans.
Global warming, what caused it?
Pollutions Who caused pollutions? It's pollutants.
Who is the pollutant?
It's living things, especially humans. Us.


We want to have a healthy world.
We want to live in a healthy world.
Fresh air, no pollutions, etc.

That will help for sure.
Just one (It would be better if it's more than that though) .
