Want to talk about the environment?

Here is the place to do so.
What do you do to help the environment?
We use things as long as possible, fix what we can, recycle everything we possibly can and compost everything we can that is organic (ie: banana peels, apple cores, grass clippings, etc.)
We use natural cleaners as much as possible. Vinegar works great for a lot of cleaning and disinfecting jobs so we buy white vinegar by the gallon. It is just over a $1 at Save-A-Lot and lasts for a while.
We avoid chemicals as much as we can and try to find safer, better ways.
What tips do you have?
