LeftoverSwap solves all of these problems.
LeftoverSwappers don't feel the need to eat an enormous restaurant portion, and instead pass it on to a hungrier neighbor, in turn learning their name and avoiding excess calories. Through increasing the efficiency of each plot of land dedicated to food production, we can reduce our intensive use of natural resources, and reduce our expansion into sensitive environmental areas.
We are reaching the ecological limits that our planet can bear, and when we chop down forests, as we are every day, to grow more and more food, when we extract water from depleting water reserves, when we emit fossil fuel emissions in the quest to grow more and more food, and then we throw away so much of it, we have to think about what we can start saving.Tristram Stuart from his TED talk.
With LeftoverSwap, there's less waste and fewer people picking through dumpsters: a win-win.
