Do you eat meat? Because if you do, the meat and dairy industry has a much bigger impact ecologically than a car does, at least in the USA. Raising beef or dairy cows requires orders of magnitude more water, land, corn feed (or even grass feed) for less calories than growing plant based sources of food would. Not to mention the conditions these animals are raised in (USA being the worst affender). So next time you take a bite of your steak, think how much ecologically impact that bite cost the world.

I eat meat on occasion, but not "just for the heck of it", certainly not in the case of beef (you're misleadingly equivocating between "meat" and beef in your post when their ecological impact is very different).

Back-of-the-envelope numbers from a quick search suggest that a day's eating beef is equivalent to driving maybe 15 miles in terms of climatic impact, a day's chicken equivalent to ~1 mile. So "only drive when you're getting at least 1 steak/15 miles worth of fun out of it", and conversely "only eat steak when you're getting at least a 15 mile drive's worth of fun out of it", seem like good principles to live by.
