What do you do to help the Environment?

Over the last few years I realized that the way I lived was not very earth friendly. So I have gradually made some changes.

1. I don't buy bottled water (I drink from the tap or filter my own.)
2. I use re-usable bags when I shop, all stores not just grocery. Plus instead of using the bags in the produce or bulk item sections I bring my own containers or mesh bags.
3. I've cut down on the use of paper products. In the kitchen I use mostly cloth towels. 1 roll of paper towels can last me over 1 month.
4. I make most of my own cleaning liquids, primarily consisting of white vinegar & water, some applications I also use baking soda.
5. I use vinegar in my laundry in place of bleach and softener (I'm in Nevada, very dry, some items require softener.)
6. I use food storage hacks to extend the life of produce (I HATE throwing away food!)

Do you have any suggestions? What do you do?
