My wife and I have a light-hearted back-and-forth about just how much we can do to help the Earth. I suspect industry and big business dwarf (like, wayyyy dwarf) anything that we can do as humans, so let’s focus on that. She says that if we each do something small, it adds up.
Amazingly, we're both kinda right. It all matters. Bonus: We save on that monthly electric bill. Win/win, right?
