Peter Thiel, Libertarian and contrarian, has invested in research for 3-D printed meat. I’m a vegetarian, but I hope it works out (despite thinking it’s not so close to happening). Most studies estimate that meat production is responsible for close to 20% of our carbon footprint. From Clay Dillow at Popsci:

“Billionaire Peter Thiel would like to introduce you to the other, other white meat. The investor’s philanthropic Thiel Foundation’s Breakout Labs is offering up a six-figure grant (between $250,00 and $350,000, though representatives wouldn’t say exactly) to a Missouri-based startup called Modern Meadow that is flipping 3-D bio-printing technology originally aimed at the regenerative medicine market into a means to produce 3-D printed meat.”
