Climate Change Is Getting So Bad That It’s Making Food Less Nutritious

A study finds nutrient levels in 43 major crops have declined since the late 1980s.

Researchers link the drop to rising atmospheric CO2, which boosts growth but dilutes minerals and protein.

Lower protein, iron, and zinc in staples like rice, soybeans, and wheat could worsen malnutrition and anemia.

Even small nutritional declines may have major health impacts for populations already vulnerable to poor diets.
