Human overpopulation turn into issues what it should not be one
There is no such thing as waste food. There are two issues that conflict:
Human overpopulation, turning what used to be renewable resources into limited ones.
Products sold and used as food when they actually are not. If you throw a piece of fruit next to a tree, you are helping nature. If you throw a piece of fish or meat you are polluting.
But if you also live in an overpopulated city then forget about all, cause there are no trees to feed, just concrete, and cause the amount of waste would make for a contamination no matter how green the food was.
People tend to forget that this planet is smart on itself.
All the dumbness come from humans. They even change the course of rivers, what a moronic overbloated ego you need to be such a dumb .
