Translation of a simple English composition

Today, one of the most serious problems in the world is global warming caused by human activities.

Places that have typically been colder in the past will face even colder winters, and across vast areas of our southwest, severe droughts will last longer than usual. This is said to be due to global warming. People find it almost impossible to sleep without air conditioning in the summer. Even more serious, global warming disrupts weather patterns, which will ultimately destroy humanity.

I believe that by planting more trees and reducing pollution, we can play a larger role in reducing global warming.

Don't wait any longer! Just do it! Do the right thing! Do it now!
