Two identical planets, Norlon and Bothar, have been discovered in a neighboring galaxy of ours. These two planets have the same type of atmosphere as Earth and are extremely similar to Earth in terms of topography and even species of animals that live on them. The main difference is that Norlon is inhabited by a species very similar to humans that emit a lot of carbon dioxide into the atmosphere. Bothar, however, has no such species on its planet. Which of the newly discovered planets will sustain life for a longer amount of time?
