In 2025, Bill Gates-backed initiatives have advanced the development of lab-grown food products, including meat and butter made from unconventional sources. A startup supported by Gates is producing butter from carbon, without using animals, plants, or oils, aiming to create a sustainable alternative that mimics traditional butter's taste and appearance while reducing farmland use and emissions. This product has faced public criticism for its unconventional origin. Additionally, there is a growing market for lab-grown meat, with companies raising funds to develop cell-based pet food using chicken cells without genetic modification. Meanwhile, concerns have been raised about the use of mRNA vaccines in livestock, particularly in Australia, where Meat and Livestock Australia is promoting experimental mRNA vaccines for cattle. Critics warn of potential health risks to humans and ecological impacts from these modified vaccines. These developments occur amid broader discussions about the safety and acceptance of lab-grown foods and biotechnology in agriculture.
