Globally, food waste is a significant problem. Roughly one-third of the food that’s produced for human consumption ends up lost or wasted. Not only does this diminish food security and contribute to extensive economic losses, but it also has an impact on our warming climate. If we were to consider the carbon footprint of food waste as a country, it would be the third largest emitter in the world, just behind China and the USA. Fortunately, there are some Australian social enterprises doing something about it.
