Earth is the greatest planet in the solar system! I don't care what anyone says. If you don't believe in Earth Exceptionalism, try breathing on Saturn. Mercury and Venus...now that's REAL global warming. Mars? Better dead than Red! Sure Jupiter's awesome...if you're really into hydrogen and helium. Don't even talk to me about Pluto...not a planet. If you don't love Earth, then go live on Uranus! Happy Earth Day!
