CREDIT: Shutterstock Food waste is costing the global economy billions each year, and governments should act quickly to reduce it if they want to save money and scale back their carbon emissions, according to a new report. The report, published this week by the U.K.-based Waste & Resources Action Program (WRAP), found that if countries made a point of reducing their food waste, the globe could save a total of $120 to $300 billion each year by 2030.
