My environmental fingerprint is probably <5% of average first-world countries people, I don't consume much, food mostly obviously, and local one, mostly vegs/fruits according to the season. no car, no pets, not a smoker, working remotely, avoiding trips as much as possible. I try to save wild life as much as possible, on every possible occasion, even if it's just moving a dead one off the road, in a better place.
At a single person level, these actions looks insignificant, but if everyone does it, it won't be since the major source of pollution is residential pollution, i.e. people, and the other sources of pollution (industry, large-scale transports...) are also driven by consumption. So if people stop over-consuming, this saves dramatically our planet, and our sibling animals. Of course governments need to foster this change
