love the food waste graph - that's one of the things that has made a HUGE difference in our lives. re-purposing leftovers. eating as much as we can. then giving it back to the earth in exchange for more food.

the same can slightly be said for water. like, if you make boiled eggs. save the water after cooling for plant watering. or, make a compost tea with it if you're in the rainy season. don't just immediately put it back down the drain!
