Researchers have linked dietary data from over 55,000 individuals with data on the environmental impacts of the foods they eat. The team, from the Livestock, Environment and People (LEAP) project at the University of Oxford, found that the dietary impacts of vegans were around a third of those of high meat eaters. They also saw a 30% difference between high- and low-meat diets for most of the measures of environmental harm.

Mind you, this is from 2 years ago: If we stopped all fossil fuels at that time, our diet would alone increase the temperature by 2°C
It is vastly proven by studies that vegans not only act different in regards of their diet but also in every other aspect, so you are not special. Vegans don’t need more cars than any other group.
Even if we could afford to kill billions each year for taste, you yourself stated that it is morally preferable not to. So what is your excuse?
I like meat and dairy and I don’t care about the moral part of it at all.
If it’s available for me to buy, I will continue to eat it.
It really is as simple as that.
