Waste not, want not. As much as half of the world's food, amounting to two billion tons, ends up being thrown away. The Institution of Mechanical Engineers said the waste was being caused by poor storage, strict sell-by dates, bulk offers and consumer fussiness. All because we want our foods to look perfect.

The study also found that up to 30% of vegetables in the UK were not even picked because of their physical appearance. This paper also suggested that half the food bought in Europe and the US was thrown away.  So all that waste turned into more waste. The study also pointed out, not only the amount of food that was wasted but the unnecessary use of land, water and energy resources that were used in the production, processing and distribution of this food. Then, there is the trash it generates as it goes out of our lives.  Interesting stuff to think about.
