OUR OWN PROJECT

Problem: The human been know that there’s not enough water because the 75% of the planet is water of these percentage the 95% is salt water, and the 1% is available water, but we continue wasting it approximately in each continent in Mexico, 280 thousands hectares are contaminated in one day, this is the first country that has the greatest amount of contamination in America.

Hypothesis

1.       If the human made some machines that purify the water without affecting in a bad way all living things, that machines are going to show until what point of our live we arrive so this is going to make conscience to the human been about the attitude we have.

Questions:

1.     How can we save the river without affecting in a bad way the living things?

2.     How does the human activity affects the rain?

3.     How the acid rain and contaminated water affects the food chain?

4.     Is a polluted river important for the society?

5.     What is the percentage of water that is available to drink? If we know that is not enough, why we continue wasting and contaminating it?

Conclution: The first causants of the pollution of water are the human activities,this ones not only contaminate the water but also the rain this contaminated rain is the acid rain.
