Climate change

 NPR -  Food production and transportation make up as much as one-third of a typical U.S. household's annual contribution to climate change-inducing emissions. An estimated 30% of food produced in the country is wasted. Once it's in landfills, rotting food creates methane — a potent gas that heats the Earth. Minimizing waste and reducing transportation might have a significant impact on the pollution that causes climate change. One possible better solution: home delivery. That’s because with a delivery vehicle, when a driver drops off your groceries they’re often also delivering to neighbors during the same run.
