Food Shortages vs Global Warming!?

I find this truly compelling, as I have never thought of linking climate change along with the issues of starvation, or food/water shortages. The newest releases of BrainWorld mag tells us about this as well food-system-shock-climate-changes-greatest-threat-to-civilization. I will discuss this once I learn more from the magazine, which tells about how climate change can play a role in making us less healthy as livestock will be given more antibiotics and food may contain in itself artificial growth/substances. Truly terrifying...is it not?!
