Deep dives
The Scale of Food Waste
Food waste is a colossal issue, with one billion meals going uneaten globally every day, significantly impacting the environment. This waste correlates with a staggering methane output, contributing to climate change, as landfills rank as a major source of methane emissions. The agricultural process itself also wastes immense resources, amounting to a greenhouse gas footprint five times that of the entire aviation industry. Addressing food waste could curtail the need for increased agricultural expansion, which is projected to be necessary to meet a 50% rise in food demand by 2050, by simply utilizing existing food more efficiently.
