How gene editing is changing the meat in our diet, from fast-growing fish to heat-tolerant cows
Gene editing is rapidly reshaping the future of the global meat industry, with scientists developing livestock and fish that are stronger, healthier, and more resilient. By altering DNA, researchers aim to create animals that grow faster, resist disease, and withstand climate-related challenges such as heatwaves. Fast-growing fish, disease-resistant pigs, and heat-tolerant cows are among the first innovations already making headlines. Supporters argue these technologies could help feed a growing population while reducing environmental impacts from farming. Critics, however, raise ethical concerns about genetic manipulation, food safety, and long-term ecological consequences. Regulatory systems worldwide are struggling to keep pace, with countries adopting different approaches on approval and labeling. As demand for sustainable protein increases, gene-edited meat could play a major role in shaping diets of the future, provided consumer trust and transparent governance are maintained. The debate continues over whether this scientific breakthrough is a solution or a risk.
