Food waste is a growing global issue with large environmental, economic, and social consequences. It occurs when good quality food is lost, uneaten, or thrown away at any point in the food supply chain which can range from farms and processing facilities to grocery stores and households. It may sometimes seem like a simple matter of throwing away leftovers or spoiled produce, but the impact of food waste is much more complex and harmful than many realize. One of the main causes of food waste has come from agriculture and the production stages of the foods. In many cases, crops are left unharvested due to market standards that prioritize appearance over nutritional value, with misshapen fruits and vegetables being rejected by retailers or consumers despite being perfectly edible. On top of this, developing countries often lack adequate infrastructure for harvesting, storage, and transportation, leading to high levels of food loss before the produce even reaches consumers. The overall amount of food that tends to get thrown away has been estimated to be roughly one-third of all food produced, according to UC Davis. Unfortunately it is in developed nations that food waste is more prominent at the retail and consumer levels. Supermarkets frequently throw away food approaching its sell-by or best-by date, even when it remains safe to eat. This is due to an unhealthy practice of cosmetic standards and inventory management systems that overstock to ensure shelves appear full. At the household level, consumers contribute to food waste through over-purchasing, improper storage, and confusion over food date labels. In many cultures, large portion sizes and the undervaluation of food also encourage excessive waste.

Food waste is not an issue simply in a social sense, but there are environmental consequences tied to this issue as well. When food is discarded, all the resources used in its production—land, water, energy, and labor—are also wasted. Since the products are wasted, it is safe to assume that the materials used to produce them are wasted as well. Agriculture accounts for roughly 70% of global freshwater use and is one of the major causes of deforestation and biodiversity loss. Food that ends up in landfills decomposes and emits methane, a potent greenhouse gas with a global warming potential far greater than carbon dioxide. According to the Food and Agriculture Organization (FAO), if food waste were a country, it would be the third largest emitter of greenhouse gases after China and the United States. Beyond environmental harm, food waste causes significant economic and social issues as well. Globally, it is estimated that food waste costs the world economy around $1 trillion annually. This includes losses for farmers, processors, retailers, and consumers. At the same time, millions of people face food insecurity and hunger. The paradox of widespread food waste in a world with nearly 800 million hungry people highlights the deep inefficiencies and inequalities within the global food system.

Fortunately, we have a range of solutions to combat food waste. At the policy level, governments can support legislation that encourages food donation, standardizes food date labels, and reduces food waste in public institutions. For example, France has enacted laws requiring supermarkets to donate unsold food to charities rather than discarding it. Retailers can also play a critical role by adjusting purchasing practices to ensure that no produce is wasted before going to sale, offering discounts on imperfect produce, and educating consumers about food waste. Restaurants and food service providers can improve inventory management and donate surplus food. At the individual level, people can make a difference by planning meals, storing food properly, understanding food date labels, and using leftovers creatively. Raising awareness about the value of food and the consequences of food waste can also shift attitudes and behaviors. Educational campaigns, community composting initiatives, and school programs can instill a culture of mindfulness around food.

As distressing as the situation may be, there are luckily many people taking action to try and prevent the situation from getting worse, with the Food Recovery Network (FRN) being a notable example. The Food Recovery Network is a student-led nonprofit organization that simultaneously tackles the issues of food waste and hunger. It was founded in 2011 at the University of Maryland, and it has since grown into the largest student movement against food waste and hunger in the United States. FRN’s mission is simple yet incredibly important in fighting food waste: recover surplus food from college campuses and food service providers, and donate it to local areas undergoing food insecurities, whether they are neighborhoods or other nonprofits that will redistribute the food. Every day, dining halls, restaurants, and campus events produce large amounts of leftover food that often go to waste. FRN mobilizes student volunteers to recover this uneaten, perfectly good food and deliver it to shelters, food banks, and community kitchens. By bridging the gap between excess and need, the organization not only prevents food from ending up in landfills but also helps feed individuals facing food insecurity. FRN operates through a network of college chapters throughout the nation, empowering students to lead local recovery efforts. Each chapter works closely with campus dining services to collect surplus food, track the amount saved, and ensure safe transportation to partner agencies or local neighborhoods. The organization also provides training, resources, and support to help chapters start, grow, and maximize their efforts and overall impact. Since its beginning, FRN has managed to recover millions of pounds of food that would have otherwise gone to waste. In doing so, it has reduced greenhouse gas emissions associated with landfilling food waste and continues to foster a culture of sustainability that prioritizes reallocating food resources to areas where they would not go to waste. By combining environmental action with community service, the Food Recovery Network demonstrates that students can be powerful changemakers. FRN’s work highlights a practical solution to both food waste and hunger.
