Did humans deserve water?

In my Environmental Managment class I am seeing the water cycle and my teacher ask to collect information and create a like a summury of what I read and tell what I think about it.

I will like to begin telling that all the water in the world is not drinkable. The world is cover approximately by 70 percent of water but only 3% of this 70% is drinkable. Nevertheless the human knowing this continue miss using it. Furthermore there are process of desalinasation but this only can be use by were rich countries because is to expensive.

If that was not enough, water is distributed in a very bad well. Since of this lots of children dies every 19 minutes of dehydration. Altough this bad distribution of water will create lots of conflicts between countries, some specialists think that this would cause the third world war.

Talking about plants, water is very important because it allowed plants make the photosyntesis to create oxygen and this make us continue living. Without wtaer plants would die and beacuse of that we will die.

To conclude I would like to said that human do not deserve water because they can not use it well and it is very precious.
