Impossible Foods and Beyond Meat are seeing so much interest in their meatless hamburgers that they're running out of product.

Veganism and vegetarianism used to appeal mostly to animal rights activists, but concerns over climate change and health are driving conventional people to rethink how much meat they consume

Demand for Impossible's food has more than doubled, plus Burger King announced a version of the Impossible patty, and White Castle, Carl's Jr., Bareburger, Qdoba and others also feature Beyond Meat or Impossible Foods items on their menus.

Beyond Meat is now sold at Safeway and Kroger, and Impossible plans to start selling in retail locations this year.

Even Ikea, known for its Swedish meatballs, said it will start testing a new plant-based version of its classic meatball, designed to taste just like meat, next year.

in 2015, the World Health Organization linked red meat to cancer and there has been such increased interest in meatless "meat" products that Beyond had to redevelop its supply chain and production processes to keep up.
