Food waste and the amount of water that is involved – A student presentation

In 2011 to 2012, US allocated 40% of corn to ethanol supplies.

842 million people are chronically hungry or malnourished

If the global food source is accounted for in 10 pieces of cookies, the amount of cookies that we will actually get to eat is less than half or only 4 pieces. Where does the other 6 pieces go? Well Food Waste…

Food Waste is such a large problem in the world. Currently over 842 million people are chronically hungry or malnourished. If the amount of food waste is eliminated completely, we can feed not only these hungry people but have left overs. Chris’s presentation on the amount of water in food waste focusing on meat suggest that meat food waste uses about 39% of water consumption in the US. In 2011, over 81 billion cubic meters of water is lost due to meat waste.

Everyone knows that the amount of water required to make one kg of meat is huge. For beef 15k liters of water is required for 1kg of meat. 6k for pork and 5k for chicken. A study by FAO showed that 2/3 of the food and water we give to livestock exits the food chain via urine and poop. The amount of water required to make the feeding cereals to sustain the livestock is huge and thus the enormous amount of water involved.

Some studies have shown that the amount of water in the US that is given to animals is larger than the amount of water that some countries has for drinking water. Chris’s presentation is not here to inform everyone not to eat meat. But to reduce the amount of waste. If the global food source is accounted for in 10 pieces of cookies, there should be at least 8 pieces to share if food waste can be reduced.

Christopher Putvinski is currently a student at The University of Pennsylvania studying in Individualized Environmental Study.
