WWF: Change the way you think about food

How do we balance the needs of a growing population with a finite planet? By the year 2050, our planet will be home to another 2 billion people. How will we feed them all? Not only will there be more people, but everyone will have more money to spend on food. Where, on an increasingly crowded planet, will we grow all of it? Picture what would happen if we could freeze the footprint of food by doubling the productivity of farming.
