Not eating meat is simply the single most impactful thing you can do to reduce human impact on climate change. Plus, it may also help your conscience, as there is a strong dissonance in our relationship with animals.
Food and nutrition is certainly important, and there is plenty of research that shows vegetarian and fully vegan diets are healthy at all stages of life; ADA recognizes this as well: https://pubmed.ncbi.nlm.nih.gov/27886704/
The amount of options available have increased dramatically in even the last few years. Talk with your doctor and try it again sometime!
The truth is, stopping the climate crisis involves everybody changing how they live in a significant way. Anything short of that and you better hope your great grandkids like eating crickets and forest fires.
The sadder truth is that the climate crisis is unstoppable so it doesn’t really matter how many cows you eat.

You think these corporations are growing almonds in the desert and raising cows because nobody buys them?
Whether the change comes voluntarily or through war, famine, and misery for future generations the likes of which we can't imagine is up to those of us alive today.
So called entitlement to breed is how life started in the first place.
Hence I don't think any real solution can come close to something as fundamental a change as "just don't have kids". To a lot of people, this equates to "why do you even bother being alive?". Folks are already annoyed if you ask them to segregate plastics by types, how do you think your "don't have kids" suggestion will pass? It's not a real plausible solution to the climate problem, all it does is infuriate 50% of the people, while solving no problem and changing no one's mind.
This is going to be a very real question to hundreds of millions of people within a few generations — because of climate change. Hopefully the people alive today think the answer is to create an enjoyably livable world for the people alive a few generations from today.
But I don’t blame them if they don’t. It’s fine to be selfish and not care what happens after you’re dead - it really doesn’t matter anyway. So have kids, don’t have kids. Separate plastics or don’t.
Also adoption exists.
If somebody doesn't want to subject future generations to the reality of catastrophic climate change, are they mentally ill?
TBH, I think anybody who has kids and still bothers to recycle is incredibly delusional.
If we just want to label people whose decisions make us uncomfortable as "mentally ill" I guess that's our right.
The difference between most and least conscientious people is essentially zero. Anybody having kids isn’t conscientious and is also a CO2-lover themselves.

No wonder. 2.5 million years of meat eating has evolved the human to what it is today.
It's also why I don't like being told to stop eating beef / meat to stop the climate crisis when fracking and other ridiculous practices are still legal.
Food and nutrition is important.
Disclaimer: I tried being a vegetarian for 2 years, I didn't feel good mentally and physically so I went back to consuming meat. I'll probably try again another time.
