Converting all hydrogen on earth would be thermal death for us even if done over centuries. While I do think that humanity is a destructive force, and we don't know how to control ourselves, that doesn't mean to me we should not develop fusion reactors. Because we haven't only grown in energy-consumption, but also in responsibility. From my point of view, we should stay on that path. Which includes looking for clean sources of energy.
