Agriculture Is the Biggest Driver

Farming occupies roughly half of all habitable land on Earth. Crop production and livestock grazing together are the single largest cause of habitat destruction globally. As populations grow and diets shift toward more meat, the pressure to convert remaining natural land intensifies.

The frustrating irony is that existing farmland could feed ten billion people if waste were reduced and distribution improved. Roughly one-third of food produced globally is wasted — lost in storage, discarded by retailers, or thrown away by consumers.
