Forty percent of the food in this country—almost half—is never eaten. We know we can reduce this waste once we put our minds to it. We’ve done it already, with great success, with energy. Governments, working with and encouraged by advocacy groups, designed programs to educate consumers and to prod manufacturers to design better products—light bulbs, refrigerators, cars—that made saving energy easier. Activists and innovators are just starting to develop solutions for food waste. We need a similar movement to build momentum behind these efforts and start bringing these solutions, literally, to the table. And to farms, stores, restaurants and dining services everywhere.
