Most of us don't worship our dads.
We have some good memories and some bad ones. I know I do. Walz reminds me, and I think a lot of other people, of the good memories of my dad. My dad is a flawed human being that struggled to do the right thing sometimes but he did struggle, and I love him for the things he taught me and the good memories he left me.
That's warm fuzzies, not worship
Technically, the carbon came from the air and returns to the air, but taking the pellets from where the tree died and turning them into pellets and transporting them to the furnace costs energy too.
Also all the tree carbon that doesn't make it into the pellets goes into the air. So the cost is greater than the gain.
If we grew trees and then buried them it could be a form of carbon capture. But we need to get the energy to do that from somewhere.
