How to Eat to Save the World

With the global population set to reach ten billion by 2050, the challenge of feeding the world in a healthy and sustainable way will only deepen. Meeting that challenge will require major, long-term systemic changes.

LONDON – There is not a country in the world that is not grappling with the serious health and environmental consequences of their people’s diets. There has to be a better way to feed everyone well and sustainably.

As it stands, roughly 820 million people worldwide lack sufficient food, and many more – often in the same countries – consume unhealthy foods that lead to obesity, heart disease, diabetes, and other life-limiting conditions. The health risks of poor diets now outweigh the combined impact of alcohol, smoking, unsafe sex, and drug abuse.

On the environmental front, global food production is the single largest source of human pressure on the planet’s resources, using 40% of the world’s land and 70% of its freshwater. It also contributes substantially to rising greenhouse-gas emissions, loss of biodiversity, the emergence of ocean dead zones, and deforestation.

    Jayati Ghosh

There is now a self-reinforcing pattern of high profits, low investment, and rising inequality – posing a threat not only to economic growth, but also to democracy.
