Inside Mighty Earth: Glenn Hurowitz on Transforming the Meat Industry

What if the biggest environmental culprits were hiding in plain sight—right on our dinner plates? While most environmental organizations train their sights on the energy sector, Mighty Earth has taken a bold, and often lonely, stand in confronting the meat industry's massive role in climate change, deforestation, and biodiversity loss. In this episode, I sit down with Glenn Hurowitz, founder and CEO of Mighty Earth, to unpack why the meat industry typically gets ignored by the environmental movement, and what he thinks needs to be done.

Glenn has spent decades fighting for the planet, from working on federal public policy in Congress to launching powerful corporate campaigns that aim to guide the world's largest food companies toward more sustainable practices. In our conversation, he explains why mainstream NGOs often shy away from challenging the meat industry, and how Mighty Earth's strategy—focusing on supply chains, corporate accountability, and the expansion of animal-free proteins—aims to fill that void.

We also dive into Mighty Earth's campaign to help supermarkets treat plant-based proteins not as niche novelties, but as core offerings. Glenn shares how enhanced meat products (think burgers that are part beef, part mycelium) can be a bigger environmental win than pure plant-based options alone, and why shifting market incentives—not just consumer behavior—is key to making real progress.

If you care about climate action, animal welfare, or food innovation, this episode may challenge you to think bigger—and act smarter—about what it really takes to feed humanity sustainably.
