One of the many dangerous things about global warming is the devastation to agriculture. What used to grow freely, will be harder to cultivate in the future.
The world's population is expected to increase by 3 billion people by 2050. In a world where 75 percent of poor people depend on agriculture, climate change will have a profound impact on their food security.
Higher temperatures in Latin America, Asia, and Africa will shorten growing seasons. Changes in rainfall patterns may lead to droughts in some areas and to floods in others. Researchers have estimated that a rise in temperature and change in rainfall could result in losses amounting to as much as $2 billion a year through reduced yields of important food crops such as maize. In other regions of the South, farmers will face greater climate variability, including more frequent and sustained intense weather events such as droughts, floods, and typhoons.
It is hard to predict where food will come from when the Bush Administration has not put any real funding into global warming research.
Scientific American notes that America's breadbasket will move north to Canada.
Even less data collected has been collected to discover the effects on fishing and aquaculture.
