Recycling food to generate more food is something that nature does exceptionally well. Now, a team of researchers has found a new way to mimic this trait: they rescued food waste destined for the landfill, fermented it, and turned it into an elixir for crops, which boosts good bacteria and could promote better crop growth. 

Ultimately, this discovery could help us grow more food, and do it with fewer environmentally-harmful inputs, the new study says.
