That’s exactly why Americans waste up to 40% of eatable food every year. This unbelievable number has sparked the “ugly food” movement, and inspired many companies to sell misshapen fruit and vegetables to consumers, rather than throw them in the trash.One San Francisco organization is taking a unique approach to this idea. The Salvage Supperclub hosts fancy dinners inside dumper truck (卸车) where they serve dishes entirely prepared with food that would have otherwise gone to waste.Josh Treuhaft, founder of these ugly food dinners, originally came up with the idea 10 bring awareness to America’s food waste problem. “There is undeveloped potential in their food that for some reason, not to their own fault, is going to waste,” he told Seeker’s Laura Ling.Treuhaft isn’t alone in his effort to reduce America’s food waste. A Change, org last year willed for Whole Foods to become part of the ugly food movement. They sold misshapen fruit and vegetables in Northern California stores.Selling imperfect produce is still relatively rare right now, which can be partially due to a supply issue rather than a lack of willing participants. Raley’s, a Sacramento-based grocery chain, started an ugly food pilot program called “Real Good”, but discontinued it after 90 days saying they had “some challenges sourcing the product”. A grower might have large amounts of ugly produce one year due to terrible weather, but much less the next year if the weather has been more ideal. Harvests constantly vary and retailers are more likely to buy ugly produce in large number rather than just a few pounds at a time.This is why organizations like Imperfect Produce and Salvage Supperclub are playing an important role in the prevention of food waste. Salvage Supperclub takes it a step further by not only buying the ugly produce, but turning it into a good dining experience as well.【1】What can we infer from Paragraph 1?A.
