Question

What happens when there arent trees to hold the soil? Is there a web that explains this?

Answer 1

it's called erosion and I'm sure there are plenty of websites to check for info on it.  try wikipedia

Answer 2

This site covers much more than soil retention by tree roots. It covers what happens when the forest is removed to provide pasturage in the section on Primary Production.

Answer 3

Go to  Alta Vista and type in Top Soil, it makes it vertually impossible to grow anything.  It's caused by Overuse of land, not rotating crops and floods.
