Space explorers, that launched from Earth, just encountered a new planet several light years away. This planet is almost an exact copy of Earth, but it is currently uninhabited by intelligent life. Upon landing, the explorers name the planet Caprica and begin learning as much as they can. They discover that the species on this Caprica are nearly all the same as on Earth, and even most of the topography looks the same. However, the main difference is that humans never evolved here. For this reason, there are no cities or cars or factories to burn up fossil fuels. Does Earth have more or less greenhouse gases than Caprica?
