THE SONG REMAINS THE SAME:

A hamburger a week, but no more — that’s about as much red meat people should eat to do what’s best for their health and the planet, according to a report seeking to overhaul the world’s diet.

Eggs should be limited to fewer than about four a week, the report says. Dairy foods should be about a serving a day, or less.

The report from a panel of nutrition, agriculture and environmental experts recommends a plant-based diet, based on previously published studies that have linked red meat to increased risk of health problems. It also comes amid recent studies of how eating habits affect the environment. Producing red meat takes up land and feed to raise cattle, which also emit the greenhouse gas methane.

● Chaser:

By the end of [1969], [lefty historian Douglas] Brinkley writes, “now that Neil Armstrong had walked on the Moon, Cronkite sensed that ecology would soon replace space exploration as the national obsession.” It certainly became, for a time, Cronkite’s obsession, often crowding out other more newsworthy stories during the critical year of 1970. At the beginning of the year, Cronkite jumped onboard the radical environmental movement wholeheartedly — “God damn it, we’ve got to get on this environmental story” — and as his producer Ron Bonn said at the time, “We wanted to grapple first with air pollution, the unbreathable air. But then we wanted to deal with the primary underlying problem, which was overpopulation.”

In April of that year, two days before the first “Earth Day” Cronkite began a regular series on the CBS Evening News portentously titled, “Can The World Be Saved?,” as the American left first began to dial up the volume of its eco-crankery to 11. To accompany those segments, Bonn created a backdrop consisting of the legendary photograph the astronauts of Apollo 8 took of planet earth, with his hand placed in front of the photo clutching the globe. “We were trying to show humanity squeezing the Earth to death,” according to Bonn.

Brinkley notes that this photo quickly became informally known as “The Hand Job” amongst the backstage production crew of Cronkite’s broadcast, much to its true-believer host’s chagrin. “We’ll need the hand job, tonight!” Which in retrospect, seems like the perfect description of the masturbatory nature of radical environmentalism.

As Glenn wrote last night, “It doesn’t matter what the problem is, the solution is always for us to give the government more money and power, while we eat less meat.”
