A third of the world's food ends up rotting in fields or is simply thrown away. It's not only a major waste, it also impacts climate change because decaying foods produces methane, which contributes to global warming. But France is attempting to do something about it. Since 2016, large grocery stores have been banned from throwing away unsold food that could be given away. Proponents of the law say it has increased the amount of food donations to NGOs and those in need, but critics worry the law does not go far enough to stop food from being wasted.
