I've had lots of thoughts on this lately, well actually my whole life I've had thoughts on this. Here's my latest:
*Cereal boxes, waffle boxes, pretty much every box of food everywhere except for pasta, has a plastic liner inside of it. I don't have to throw it away, heck no! I can dump out the crumbs, maybe throw some water and soap in there, splash it around, let it dry for a bit, and I can use those things for packaging material. Or maybe as a stuffing for a child's toy (apparently babies love that crunchy sound).
*I don't have to drain my dishwater since I'm using Eco Dishmate, I found out that it's safe to use this wastewater for plants. Graywater is fine for plants that you don't eat! Yessss!
What else can we do? I'm not bragging here, let's share information. Maybe there's more stuff I could be doing besides biking, bringing my own bags everywhere, r/r/r, etc. Even though I feel like I'm way beyond turning off the faucet while brushing my teeth (I remember a specific Sesame Street cartoon-vignette where it showed the pond draining and the fish getting really scared as the kid brushed their teeth), I still feel like I could do more reducing.
