Reducing your meat consumption is likely the most effective way of lowering your personal climate 'footprint'.
You don't even have to go fully vegan. Use 20%, 30% or 50% less meat and you're already doing a lot.
Also look up climate impact of different types of food (and where it comes from), and use that to prioritize. Chicken, fish and pork are up to 10 times less impactful than beef.
Thank you!
Imagine what the FOSS CAD space would look like if AutoCAD etc didn't offer anything for makers!
