Humanity’s hunger for meat is not good for the planet. Every cow, pig and fish that farmers rear has an environmental cost – particularly in the land and water resources it takes to grow the food the animals eat.

Using methane-eating bacteria, they have developed animal feed that uses a fraction of the land and water of plant-based animal feed.
