The Future of Food
Towards a Sustainable Food System for a Planet with 9 Billion People
Since the dawn of agriculture, humans have been converting forests, grasslands, and other ecosystems to farmland. While climate change, air and water pollution, and a range of other environmental challenges frequently get the headlines, food production without question represents the single largest human impact upon the environment. Land for crops takes up 12% of Earth’s ice-free land. Add pasture and that percentage climbs to 36%. The long-term conversion of land for agriculture has brought enormous losses to ecosystems and wildlife populations already. The climate impacts are also considerable—15% of global greenhouse emissions come from the agricultural sector. With global food demand expected to grow as much as 70% by 2050, those impacts threaten to grow substantially.
