How does Brazil Misuse or Mismanage the water supply?

Question

I am doing a presentation on this, and I need two wasy this country is misusing their water supply and how could they change this way to better the community around them?

Answer 1

Deforestation has a major impact on the watersheds. If deforestation of the riparian zones (trees right next to the river) it would prevent flooding and large amounts of sediments from filling the rivers.

The second is pesticides. Brazil's massive farms used large quantities of pesticides, herbicides and fertilizers which have wipe out aquatic ecosystems and in some areas make it impossible for farmers downstream to use the water.
