Bill Gates: 'Climate Change and Population Growth Will Cause Starvation by 2030'

"Climate change is the biggest threat to our food supply since the invention of agriculture."

Bill Gates: "The twin challenges of both population growth and climate change", if left unchecked, will cause "huge amounts of starvation".

"The projection, just for 2030, is 32 million more hungry people... Most of that is going to be women and children."
