World Food production relies heavily on oil for fertilizer, production and transport. So with the spike in oil prices food become for many poor people unaffordable. Starvation and malnutrition was the immediate consequence for these fellow humans.
So each time food is wasted, oil is wasted.
Conservation should be a commandment for every human on this planet. Especially since overpopulation on one side and the destruction of the environment seriously limits the food supply.
So if you throw away food, you are not killing poor little babies in Africa – but you are certainly wasting a valuable resource.
People in rich countries don’t have to live total frugal, but some efforts to cut down on waste should be made anyway.
