- stupid question - if everyone on the entire planet went 100% vegan from tomorrow, will carbon emissions really go down by 60%?

Carbon emissions from food production may go down about that much. However, those emissions are only about 30% of the total CO2 emissions humans are responsible for, if I recall correctly. So, total CO2 reduction would be about 18%.

This comment makes me so, so angry. Like, shouting angry. It's a person who hasn't engaged with a topic AT ALL except to find one headline that downplays the concerns of others. It's the quintessential bad faith comment, created of willful malice or ignorance (and I don't mean that be aggressive, but descriptive). Which is more true: are you trying to comfort yourself with this comment, or do you find those who work…

maybe, but only because a lot of people would starve... that's a demand change our food supply isn't currently structured to handle long term with a proper transition, probably not 60% but likely some lower double-digit percentage (maybe closer to 20?)

We grow a lot of human-edible food for the sole purpose to feed it to livestock, who then spend most of those calories on existing and put a small portion into body mass that we eventually eat.

Sure, that stuff isn't of the same quality as food grown for human consumption, but putting livestock on a diet and diverting some of their food to human consumption would more than cover any shortfall from the missing meat

It's called evolution. Unfortunately the rate at which we are changing the climate is causing a mass extinction and die-off event. In the article it says "does not mean that polar bears are at any less risk of extinction". Doesn't sound like 'adapting nicely' to me.

Im actually a Cambrian explosion of anti-human defenses. Allergens, toxins, whatever kills them and drives them indoors, life will adapt and shepherd. Nature is no virgin goddess ravaged by evil industrial mankind - nature can be hard and fast - almost as if life depends on it.

and likely other un predictable knock on effects would reduce the benefit, like going vegan would mean more food is available overall, and population might rise in response.

Earlier quoted context omitted.

Most of the emissions are done by the 100 biggest corporations. That's where I'd start fixing things.

Don't corporations just serve their patrons?

"just" is a weasel word there. Decisions are made and policies are enacted based on a number of factors.

I want to ignore these articles as it is so painful to watch the beautiful clockwork of the natural world unravel. I hate facing the suffering, diminishment, and extinction of so much in the name of profiteering and ever-increasing growth. But this is the world now, there will only be more stories like this, and so I'm not turning away from it any further. The world becomes less beautiful, less rich, less full every…

You have articulated my feelings, behavior, and outlook almost exactly. I feel so hopeless every time I read an article like this. I've joined climate activist groups and meetups, and I've donated to orgs and political candidates. But I just feel like there's so much more damage to be done before we get to substantial improvements, it's so disheartening
