Rising carbon levels in the atmosphere can make plants grow faster, but there's another hidden consequence: they rob plants of the nutrients and vitamins we need to survive. In a talk about global food security, epidemiologist Kristie Ebi explores the potentially massive health consequences of this growing nutrition crisis -- and explores the steps we can take to ensure all people have access to safe, healthy food.

Kristie Ebi: How climate change could make our food less nutritious

How climate change could make our food less nutritious

Rising CO2 levels, while boosting plant growth, also diminish food's nutritional quality, affecting proteins and vitamins.

A study predicts by 2050, changes due to higher CO2 could exacerbate iron and zinc deficiencies, impacting millions globally.

Without research funding, we're blind to CO2's full impact on food nutrition, urging a reduction in greenhouse gas emissions.
