From the Treehugger.com article:

The money it would take to increase food production by that large amount is in the billions and even with best estimates, hundreds of millions of people will still starve by 2050, reports the BBC. Is there anything that can be done?

By 2050, the worlds population is expected to rise from 6.7 billion to 9.1 billion and feeding that many extra mouths, plus finding the space to grow the food to feed that many mouths, is going to take a serious amount of work and the FAO reports that we literally need to start today. That’s before we factor in the droughts, floods, water scarcity, fluctuating temperatures, and other problems that will arise from climate change, essentially tying one hand behind our back while we try to grow our own food to feed ourselves.

Will we bother to act?

Of course we won’t!
