Food waste directly causes artificial inflation of food demand, which is reflected in excess agriculture, agriculture being one of the greatest source environmental damage currently. Emissions (throughout the entire supply chain from the farm to the table), soil compaction, runoff and other pollution are all externalized by Big Ag (meaning we as the people of the world pay the cost) and we amplify this when we waste food. That’s not even getting into the excess waste management involved or the direct hit to our GDP from food waste. It’s a big deal.
