I sure do!

I use the pooper scooper biodegradable bags for cleaning the cat box. A small package lasts forever.

My kitchen garbage bags are biodegradable also...I have to pay for them, but big deal. Planet Earth is worth it!

I have reusable grocery bags - heavy synthetic/cloth ones, and a plastic grocery bin for large trips. Many of the ones here have the writing "bin shopping" on them.

I dream that one day it won't be unusual.
