regions are likely to experience water shortages. Coupled with
increasing demand, this is likely to result in large increases in the
number of people at risk of water scarcity. It is likely to affect
livelihoods, the report by the International Panel on Climate Change
Projected reductions in the area suitable for
growing crops, and in the length of the growing season, are likely to
produce an increased risk of hunger. In some countries, yields from
rain-fed agriculture could be reduced by up to 50% by 2020.
Rising sea levels threaten large cities.
Degradation of coral reefs and mangroves is likely, with impacts on
local fisheries and tourism.
Rising temperatures, coupled with over-fishing,
will decrease the supply of fish from large lakes, with important
impacts on food supplies."
Recently I had the pleasure

The instructor, Dr. Wilson, was kind enough to let me take the material
available to the students and posted it on my web site. So, here it is:
"Nature loss 'dwarfs bank crisis'"
- read on comparison of the current financial crisis and the real crisis
