Buying secondhand over new. I love thrifting so that’s a bonus for me! Also using what I have, repairing what I can, or just going without something versus buying something in the first place.

Eating less meat, and prioritizing locally grown veg when possible.

Taking public transit, walking, or biking everywhere. If going long distance, I try to take ground transportation (trains, buses) over flying.

Reducing energy use eg turning off lights when I’m not in the room. You’d be surprised how many people still don’t do that, haha!
