f greenhouse gas
emissions are not curtailed soon, then global warming may bring about the most
sweeping re-arrangement of ocean species in at least 3 million years, according
to a new study, according to Andrew Freedman, writing on Mashable Australia.
The study, published Monday in the journal Nature Climate Change, shows that by the
end of the century, the polar regions may be have some of the most abundant and
diverse sea life of anywhere on the planet, while the tropics, which are
currently the crown jewel of marine species richness, may be drained of much of
its iconic marine life.
The stakes involved in which ocean species live where are
high since, globally, we depend on proteins derived from fish, crustaceans and
mollusks for up to a quarter of our animal protein intake, according to the
World Health Organization. In 2010, fish provided more than 2.9 billion people
with almost 20% of their intake of animal protein, according to the Marine
Stewardship Council, and 4.3 billion people with about 15% of such protein. In
some countries, these figures are higher.
