Ocean Acidification Threatens Food Security: Report "Pakistan,
Thailand, the Philippines, Iran, and China are among the top 50
nations whose food security may be threatened by the effects
that the rise of manmade carbon-dioxide (CO2) gas emissions are
already starting to have on fish and shellfish, according to a
new report by Oceana, an international ocean conservation
organization." "While global warming is expected to affect the
food supply of many nations by increasing drought, heat waves
and torrential downpours, this report focuses on countries that
depend heavily on the oceans for sustenance. ... In order to
assess which countries are at greatest risk, Huelsenbeck and his
colleagues looked at two entirely different effects of CO2 on
the oceans: the warming caused when carbon dioxide traps extra
heat from the Sun, and the rise in the acidity of seawater as it
absorbs some human CO2 emissions to form carbonic acid."Source:
