This makes statements like "Eating less meat won't save the Planet" (obviously true) and debunks obviously false straw-man hyperbolic claims like "cows are polluting the air with their methane rich burps, they're eating all our food, drinking all our water, and taking all our land that we could be using to grow human food on" (0:15).. At the end (19:28) they even say that reducing meat is a smokescreen to deflect from reducing fossil fuels - whereas of course hardly any environmental advocate deflects from fossil fuels (though of course a short cherry-picked clip of some animal rights activist not mentioning the systemic issue of fossil fuels was found & used).
It also states that going vegan won't make much of a difference (even if true you could argue that almost all necessary actions won't make "much" of a difference by themselves), cherry-picks examples of "bad" plant-based foods, doesn't seem to account for crops being fed to animals (including for "finishing" cows), and states that methane emissions are part of a natural cycle that's been happening historically (perhaps true for US but we'd still have less warming if this methane was much reduced!).
Some of his points seem valid though - e.g. ruminants making use of "marginal" land where mostly grass grows, but this is specific to ruminants whereas the video title just says "Meat". I agree that in many situations beef is indeed environmentally better than chicken & pigs, whereas in other situations, like when the Amazon gets destroyed, it's worse. So he could have written "Eating less Beef won't save the planet". (BTW, since cows are large beef also results in less killing per pound of flesh)
So how about both Meatless Mondays and No-Food-Waste Wednesdays (22:37)... Food Waste is certainly terrible & should have much more focus.
