Let's see who is doing the denying.

I will try to make this easy for you, all you need to do is answer yes / no to each question:

1. Does the energy required to grow the shoot of a tree to the point it shoots leaves, flow in the opposite direction of the energy from sun to Earth?

2. Does the energy flow in the tree change direction, from the point it grows leaves, to start flowing from leaves to Earth, after those leaves begin collecting energy from the sun?

3. Does the total energy transferred by the tree in its lifetime as above far outweigh the energy it took to grow the shoot?

4. Does the adult tree grow to a size much larger than the shoot?

5. Can we copy this action of the tree, as a species?

6. Should we copy this action of the tree, using all the technologies at our disposal?

7. Are we not just doing exactly that?

8. Are we not just an infant species, raised to date on energy from the materials of Earth (Capital), now in transition to the energy of the sun?
