Almost a third of all food produced globally—enough to feed everyone in the world for two months—is lost or wasted, the UN’s Food and Agriculture Organisation (FAO) says. It also causes around 8% of global greenhouse gas emissions and consumes about a quarter of all the water used by agriculture. When it comes to the cost to the climate of food produced but not eaten, YieldWise puts it at 3.3 billion gigatonnes of CO2 and 66 trillion gallons of water annually. The FAO puts the global impact of lost and wasted food in context, saying that producing the total amount requires a cropland area the size of China.
When you reside within a capitalist system and operate through capitalized markets for profit motive, you guarantee wasteful consumption and allocation of resources. As profit has no restraint upon management of resources besides profitability as the pinnacle.
