Food Waste is the food which is produced but not eaten, because it is either lost or discarded.
Shockingly the meat lost (and the greenhouse gas has still been produced) is equivalent to 75 million cattle a year. This information is that of the United Nations Food and Agricultural Organisation from 2013. Although there may have been some change given the efforts that have been made, I am sure the figures are still substantially as shocking as they were then.
The picture for other products is just as bad – you can click the images to reach the infographic online, where it is more legible.
