Galileo was not the only guy that thought the earth was round. That tidbit had been settled since the ancient greeks. http://scienceblogs.com/startswithabang/2011/09/21/who-discovered-the-earth-is-ro/ https://en.wikipedia.org/wiki/Myth_of_the_flat_Earth I agree - and the point I tried to make (albeit clumsily based on the response) is that it doesn't matter to me because in the end, I'd like clean air and water regardless. The thread was about earth day and it turned into an anti climate change fiasco. Earth day isn't about global warming - it is about taking care of the environment - and that includes clean water, clean air, clean oceans, etc. not just climate change.
