A new book covers one more reason humanity needs to tackle global climate change, and tackle it fast: we'll starve to death if we don't.
That's the argument put forth by Professor Julian Cribb in The Coming Famine: The Global Food Crisis and What We Can Do to Avoid It. Cribb writes that a global population of 9.2 billion by 2050 would double our current food requirements, and vastly outpace the growth in our food production capabilities.
Extreme weather patterns will contribute to droughts that afflict the worlds poor. Food riots and war will break out. The demand for protein foods like meat, eggs, and fish will cause prices to skyrocket.
Cribb's vision may sound like the far-fetched plot of a sci-fi film, but research already predicts a massive die-off of coral reefs as ocean dead zones expand. Scientists have already said we'll be out of fish by 2050. Oh, and more than 2 billion people will face water scarcity—with an additional 5 billion facing moderate shortages.
Unfortunately, there's little hope that negotiators at the current Cancun climate conference will come to any meaningful agreement. So do we just kick this can down the road some more?
