Question

Whats an enviormental issue in the desert?

Answer 1

One of the major threats to deserts are blown sand storms caused by off-road vehicle use.  4x4's and ATVs loosen up the desert surface which frees sand particles and sends them airborne.  High winds then carry the sand long distances (and can be mixed with industrial pollutants) which are responsible for human health effects and deteriorated air quality in some urban locations.

Answer 2

Drought mainly.  Also wild fires (because it's so dry).  And it there is a heavy rain it's susceptible to mudslides and avalanches.

Answer 3

I believe in China that the desert is growing larger each year.  I'm not entirely sure, but I believe so. You'd have to look it up to be certain.
