Or we can accept people will keep their diet and go on with our lives. Just because something impacts the environment (literally everything does this btw) doesn't mean that we need to stop doing it. The climate will always be changing and humans will always have some impact on it. We need to accept that as fact.

That's pretty much saying "I put my personal food taste before the safety of the future generations.". Don't get me wrong, you're free to have this opinion but it's probably a good thing to frame it like that to fully understand the choice.

There's "climate is changing" and massive population migration, uninhabitable areas, unreliable food and water supply, sea level threatening entire cities and probably more.

The fact that "literally everything we do" impact the environment isn't a valid argument. It does seem daunting, but by looking at each cause individually and acting on it, it looks less discouraging.

I'm far from perfect, I'm not even vegan and I still fly quite a bit, I just came to understand I had to make progressive changes to my behaviour or the human existence we currently have is severely threatened,

Which doesn't abdicate us from preventing harm. My grandkids, if I am even lucky enough to have them, are going to live in a world where at least 31 days of the summer month will be too hot to go outside, winter will mostly be bouts of torrential super-storms, food will be incredibly expensive, and the politics of the day may very well be battles over how to handle the billions of migrants fleeing the uninhabitable places of the world.

Climate change is already displacing tens of thousands of people every year to floods, forest fires, and arid land. It's going to get worse before anything we do today to survive has an effect.

I think the thousands of scientists studying this phenomenon already understand the impact of human civilization on Earth rather well.
