Almost 1 billion people around the world don’t get enough to eat. Climate change, which is already contributing to food-price increases in poor and prosperous countries alike, promises to make it even harder to feed a growing population.
The world produces enough food to provide its 7 billion people with the roughly 2,700 calories they need daily. But agriculture and food supplies are highly vulnerable to the extreme weather that comes with climate change. As the population grows -- it might reach 10 billion by 2050 -- the world will need to boost farm productivity and solve logistical impediments that make it hard to get food to those who need it.
