How does food production and consumption affect the environment? Research has found that global food production is the single largest human pressure on Earth. More than 85% of water used by humanity is claimed by agriculture. It uses 40% of the Earth’s land area and is the primary driver of deforestation, habitat destruction and biodiversity loss. Food production is responsible for a quarter of the world’s greenhouse gas emissions, equalling the contribution made by electricity generation and exceeding that of industry.
