What's Left to Eat?
It could be the plot of a scary movie but, unfortunately, it's all too real. More than 800 million people on Earth do not get enough to eat. And a quarter of those empty bellies belong to kids.
By the year 2050, more than four billion people may go hungry. Temperature, rainfall, droughts, pollution, floods, urban sprawl , disease, and politics all affect the world's food and water. Modern farming can improve food production but can also deplete water supplies and poison land. Technologies such as modifying plant and animal genes may offer solutions, but can cause problems too.
