Understanding of the importance of reducing food waste is growing. France has recently become the first country to prohibit supermarkets from throwing away food based on its sell-by date. They are required to donate the food to a charity rather than dispose of it.
We may be a long way from mandating food donations nationally, but there is a lot that we can do in our own homes. Within the US, we are responsible in our homes for 43% of the food waste.
