Globally, a staggering one third of all food that is produced is never eaten. That waste—more than 1 billion tons annually—fuels climate change. As organic matter decomposes, it releases methane, a greenhouse gas that is much more potent than carbon dioxide when it comes to warming the planet.
The United Nation estimates that up to 10% of all human-produced greenhouse gases are generated by food loss and waste. That's nearly five times the emissions from the aviation industry.
