    None. They are called trees. We should stop wrecking things.

      To be fair trees still use energy for doing this, but that energy is conveniently provided by the sun.

        If humans could make a profit off of killing the sun, they would.

          We should try with solar farms

            How does that destroy the sun? Unless I have the wrong idea of what a solar farm is. I’m imagining a big ol’ flat farmland in the middle of kansas with thousands of solar panels.

            Dyson swarm goes brrrt.

            I know it’s not killing the sun, but we’d be hogging up all that sunlight from other planets in the solar system.

              Eh, the only other places in the solar system that could have life get the heat from tidal forces. I don’t think they will miss a bit of solar energy.
