soils are lost for agriculture
The difference between DESERTS and DESERTIFICATION
Deserts are natural ecosystems, beautiful in their own right, and
should not be confused with desertification, which is a rapid
process that follows environmental degradation, turning
hospitable areas into a no-man's land.
The satellite images accompanying this article show several
examples of drastic environmental changes caused by
unsustainable practice and / or climate change.
The extent and rapidity of change caused by human activities
is impressive. Although not easily noticeable on a day-to-day
basis, comparison between two images taken only a few
years or decades apart reveal the dramatic change that
desertification can cause over a short period of time.
This should inspire us to respond more forcefully to such
human and environmental tragedies.
