I regularly install home improvements, like better insulation, replace drafty doors, windows and etc to save heating resources.

I also do composting: instead of throwing away anything organic i do it in a compost vat and wait until it turns into a nutrient rich substance to throw in my garden. I barely mow my garden to let it be wild to support insects like bees and butterflies.

I take the bike as much as i can instead of the car and eat almost exclusively vegetarian and don't waste food as much as i can.

My electricity is 100% renewable and if i donate or invest it's in ESG/SRI companies. So no support for fossil or unethical industries.

I don't order useless fragile stuff that takes a long way to get here while it breaks in a week.

Long story short. I try as much as I can as a person and educate everyone in my family and myself the best as I can.

Sorry it's not a specific deed but a way of life can matter too i guess? 🙂
