Back in the 1600's colonists introduced farming to the Amazon. In order to get enough soil to farm, they used the "slash & burn" method to remove all the vegetation from the area. Unfortunately, rainforest soil is typically very poor, and the Amazon's is no different. Crops can't survive more than a few seasons before the ground runs out of nutrients.
If a poor farmer's crops die, in almost all cases he will move on to the next patch of "available" land. In this case, by "available" we mean "occupied by rainforest." So one farmer might be responsible for the loss of tens of acres in his (or her) lifetime.
If you count up the number of people doing this, it really adds up. On average for the past three decades, the Amazon has lost 20,000 square kilometers a year. 20,000! If you think any forest is large enough to survive that, think again. If things don't get better soon, there may not be an Amazon rainforest by the end of the century.

a lot of rain forrests are in danger because the thin top layer of soil is very fertile
expanding populations and expanding farming ,that has to keep pace with the expanding populations are very strong forces that encroach upon the rainforest's
clearing them for farming and settlement areas .
In Mexico is a famous jungle that the Media has been trying to save for years
the Naturists ,and the government ,keep watch .laws are made for protection the wild and to forbid logging.
TV put out a series of documentaries
there are campaigns in the News papers
and all of this has not made the slightest difference
Rainforest's always are in third world countries and always in third world countries corruption and the need for money s highest
the jungle gets smaller by the day
more and more farmers move in .and burn the trees
it is an impossible situation
as long as there is poverty in these regions the destruction will continue

It's due to the out of control logging that's going on and has slowly but ever so surely been destroying a very old and extremely vital, to the Earth's survival, habitat.
