Meat production is projected to nearly double by 2050 to meet growing global demand. But the way the world currently produces meat cannot meet this demand and still achieve global climate, food security, public health, and biodiversity goals. Making meat differently via alternative proteins can help feed a growing world safely and efficiently, and will be as essential to mitigating climate change as the global transition to renewable energy. When compared to conventional meat production, alternative protein production dramatically reduces emissions, requires far less land, eliminates the use of antibiotics in our food system, and feeds more people with fewer resources. By reimagining protein, we can produce food that people love and usher in a more sustainable, secure, and just food future. Countries have committed to halve emissions and protect 30 percent of global land and ocean ecosystems by 2030. With just seven years to go, investing in alternative ways of making meat, seafood, eggs, and dairy is essential.
