Making small changes to how we eat, farm, and produce food could save almost a quarter of agricultural land globally. This challenges the idea that big environmental wins can only result from huge, ambitious changes, say a team of British and German researchers on a new study.

Currently, agriculture uses up almost 40% of all land on the planet, and with food demand set to rise by 116% by 2100, that will only expand—eating into wild habitats and furthering climate change with the expulsion of greenhouse gases.

But if we make a fleet of 29 achievable changes in combination worldwide—everything from replacing red meat with chicken, to reducing post—harvest losses, and using food waste as animal feed, we’d free up 21% of currently—farmed land.
