Thor: God of Thunder #4

Plot

Thor battles on two fronts to save the Earth! Thor has always fought to save his adopted home of Earth. But who can he fight when the planet itself is dying? Thor's ally, environmental secret agent Roz Solomon, has a few ideas...namely the world's most nefarious energy company, Roxxon, and its ruthless new CEO known as "the Minotaur!" Has Thor finally met his match in the form of a multinational super-corporation? Meanwhile, many millennia from now, a future Thor faces a very different battle to save what remains of the earth - a battle against Galactus, the Devourer of Worlds! King Thor is all that stands between Old Galactus and the planet he's been dying to eat for a very long time. But even if Thor wins, is the Earth still doomed?
