Human-made fertilizers have greatly boosted crop production, letting farmers grow more food on less land. But this uptick in fertilizer use has come at a cost: planet-warming greenhouse gas emissions.

Soil-based carbon sequestration is a way to remove CO2 from the air and store it somewhere it can’t easily escape: in soils, which store carbon in the form of broken-down plant matter.

Wildfires are becoming more frequent and severe as a result of climate change, as forests in arid parts of the world become hotter and drier.

Agriculture is likely to face severe impacts from climate change. At the same time, the production, storage, and transport of food contribute to climate change.
