The Planet Will House 10 Billion People, and We Can Feed Them All

There are a few basic (but radical) steps we can take to sustainably double our food production. Here’s the strategy:

• Halt farming in places like tropical rainforests and wild lands, which are ecologically valuable but have low food output. 
• Make underused expanses of land in Africa, Latin America, and Eastern Europe more efficient, boosting current food production by nearly 60 percent. 
• Make better use of water, fertilizers, and chemicals 
• Stop eating so much meat, especially in developed countries. 
• Stop wasting food—about one-third of all food grown is either discarded, spoiled, or eaten by pests.

The last two one can start doing today.
