How can the world nutritiously feed nearly 10 billion people by 2050, in a way that supports rural development and tackles climate change?

Reducing food loss and waste are an important part of this strategy.

There are more than 500 dead zones — areas of the ocean without enough oxygen for most marine life to survive — from untreated wastewater.
When people talk about climate change, the planet-warming gas that invariably comes to mind is carbon dioxide. 。
