How food waste influences energy resources

Ecologically speaking, there is no 'waste' but a long chain of conversions of energy and matter from one state to another.>>

What may appear the waste of one species becomes the meal of another species all the way down to the basic microbiological processes of decay. In nature nothing gets wasted; it only changes form, location and utility. However, wastage of food potentially contributes, through large over-production, to unnecessary global warming as well as inefficient resource utilization.Where extensive surveyed data exists, such as in the UK, for example, about seven million tons of food is thrown away from homes every year. Even more striking is that £1 billion-worth of the food wasted annually in the UK is food still 'in date' and so is perfectly edible. If just this quantity of food was not wasted, the saving in energy consumed in its production, packaging and transport, would be the equivalent of taking 20% of cars off the road! Moreover, the pressure to increase production further puts a huge burden on fragile eco-systems, on the long-term quality and availability of potable water and the habitability of natural terrains.
