20% of the world's population consumes 80% of its resources.

I chose this sentence because it is very shocking. It sentence says that the population consumes more that produces resources. In my opinion this fact should change, because if doesn't change all the resources in the world will finish.

Some examples are:
-we must not make bad use of resources, for example when we wash our hands, we shouldn't leave the tap on while we are not using it.
- Put a water regulator on the taps.
- We must not waste food.
- etc...

In conclusion If the world's population changestits lifestyle, these figures may change someday.
