The way we produce, consume and discard food is unsustainable. A new report from an independent body of scientists warns that we must rethink our food system and quickly to avoid the most devastating impacts of deforestation, biodiversity loss and unchecked climate change. While its not often recognized, the food industry is almost on par with fossil fuels as a driver of climate change. As todays report by the Intergovernmental Panel on Climate Change warns, to reach the 2030 target of reducing emissions by 50%, we need more than reforms by the energy and transportation sectors we must also reform our land use and agriculture practices.
Currently, the global food system is pushing our natural world to the breaking point: The production, distribution and consumption of food currently accounts for more than one-quarter of all human-caused greenhouse gas emissions. But by addressing food waste and emissions from animal agriculture, we can start to tackle this problem.
Livestock production is a leading cause of deforestation, water quality-degradation and air pollution. In fact, animal agriculture has such an enormous impact on the environment that if every American reduced their meat consumption by just 10%, we would save approximately 7.8 trillion gallons of water more than all the water in Lake Champlain. Wed also save 49 billion pounds of carbon dioxide every year the equivalent of planting 1 billion trees.
Whats more, to the injury of food production, we add the insult of food waste: Globally, nearly a third of all food produced ends up as waste. That means were throwing away $1 trillion, or about half of Africas GDP, every year. At our current rates, if food waste were a country, it would be the worlds third-largest emitter after the U.S. and China.
We need a new way forward. To ensure global food security and sustainable food practices in an ever-growing world, we need an approach that reexamines our global food systems through a lens of regional resources, economics and culture.
To start, the United States and other developed countries must use incentives to encourage companies to produce more sustainable food, including more plant-based options. Leaders must create policies that ensure low-income communities have access to affordable fruits and vegetables. And we all can do our part to reduce food waste, whether its in our company cafeterias or our own fridges.
Technology also plays a part. Developed countries should support and incentivize emerging innovative technologies in plant-based foods, as well as carbon-neutral or low-carbon meat production.. Additionally, developed countries should focus on retailer and consumer education to inform decisions about healthy and sustainable diets.
Developing countries, on the other hand, face high levels of undernutrition, as well as limited access to healthy foods. Many nutrient-dense foods (such as fruits, vegetables and quality meats) are highly perishable, often making prices significantly higher than ultra-processed, nutrient-poor and calorie-dense foods. The high cost of nutrient-dense foods creates a significant barrier to healthy diets, as seen in urban Malawi and many other countries.
By promoting enhanced production of healthy and nutritious foods while also improving markets in low-income countries, we can lower prices and increase accessibility of healthy and sustainable diets. Politicians can also tackle systemic inequalities by reshaping agricultural subsidies away from staple crops to healthy foods, as well as investing in infrastructure like rural roads, electricity, storage and cooling chain.
From top to bottom, people and partnerships will play a big role in this new approach. International participation and resource sharing can spread regional solutions across countries. And working for change at the ground level among individuals, communities, local and federal governments and private entities can help fight hunger and food inequality firsthand.
As todays global report demonstrates, our food system is broken, but not irrevocably so. Its time to demand a new way forward. The challenges are enormous, but by understanding the problem and potential solutions, we can take urgent and profound changes in the ways we produce, consume and dispose of food. Its a food system ripe for change, and the time to act is now.
