During my lifetime, the
human population of this planet has tripled from 2.5 billion to 7+billion.
It is expected to reach 10 billion by the time I leave. We are
going to need a LOT more food. Will it be there?
Demand
is expected to rise as much as 14 percent each decade, as the world population
is projected to grow to 9.6 billion in 2050, from 7.2 billion today, according
to the United Nations, and as many of those people in developing countries
acquire the money to eat richer diets.
Scientists
from a United Nations panel, the Intergovernmental Panel on Climate
Change, conclude that rising temperatures will have some beneficial
effects on crops in some places, but that globally they will make it harder for
crops to thrive — perhaps reducing production over all by as much as 2 percent
each decade for the rest of this century, compared with what it would be
without climate change.
