It's the third or fourth one I've read by David Bach recently. Tips on going green and saving money. I already do things like recycle paper and plastic, and upgraded the house 🏠 windows for less leaking. I drive a smaller car that gets decent gas mileage, but will try to do better next time (in a few years). Of course, during the pandemic I'm driving significantly less, so saving $. Will check out the green investments. 4 ⭐s
