What is your favorite way to give back to the environment?

I started using soap bars for shampoo and conditioner. I started using floss picks made of bamboo. I compost food scraps. I have started using reusable beeswax wraps. I got an electric toothbrush that has replaceable heads and I plan on buying replacement heads of bamboo only. I also got an electric razor and plan on using that instead of disposable razors. I stopped buying clothes. I don’t toss plastic bags I save them and reuse them for when I walk my dog or need something to throw up in on the go. I have also stopped buying paper products like paper plates, napkins, paper towels. What are some of your favorite ways to be kind to the environment?
