#20 - Bruce Friedrich on inventing outstanding meat substitutes to end speciesism & factory farming
Bruce Friedrich, Natalie Cargill, Keiran Harris, Rob Wiblin
The Good Food Institute executes a strategy to displace industrial animal agriculture by accelerating the development of plant-based and clean meats that compete on price, taste, and convenience rather than ethical appeal. While current market share for alternatives remains below 1% amidst a record 9 billion annual animal slaughters, industry experts project cost parity with conventional meat within a decade through bioreactor scaling and synthetic biology. Operating as a rapidly expanding nonprofit funded entirely by philanthropy, the organization targets a 2050 vision where these technologies collectively fulfill 100% of global meat demand.
