The quote in the title is from Bill Maher. Below is a summation of the two excellent articles posted above related to lab-grown meat having a dramatically positive effect on environmentalism.
Lab-grown meat can reduce land use by 99.7%, drain 84% fewer gallons of water and reduce greenhouse gas emissions by 98.8%.
No matter the news on health and environmental outcomes, most people are still going to want to eat a burger. So why not try to make sure that the meat we do eat has as little environmental impact as possible?
The trick is to harvest stem cells from the muscle of a live cow or pig and turn them loose in the right environment in a lab. A single stem cell can generate a hundred trillion cells of meat. So, from a small number of donor animals, we can ultimately get our burgers, chops, and chicken tenders without harm to the cows, pigs, or chickens.
What does the world look like right now? Every year, farmers raise and slaughter some 77 billion animals for food. That’s 10 animals per person. With a billion or two more of us on the planet by 2050, and with rising incomes allowing a greater appetite for meat, that number could expand. Perhaps even to 200 billion, if China and other populous nations start eating as much meat as Americans do. We cannot go there and expect to preserve our water, soil, forests, grains, and Earth as a whole.
Given time, we might even be able to fulfill a promise made by none other than Winston Churchill. In 1931, Churchill predicted that we would one day “escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium.”
