Here’s how we do it. We need to convince the oil companies that there is oil on Mars. Stay with me here. The oil companies will then fund manned space flight to Mars so they can drill for the oil. If they eventually find it, it will prove there was once life there, which will cause the religious fundamentalists’ heads to all explode in unison (side benefit there). Then, because using the oil on Mars would be way cheaper than shipping it to Earth (not to mention supply and demand), we could then send all of the SUVs and sports cars (and their drivers, another side benefit) to Mars. This would also have the side benefit of decreasing congestion here. Then, all the green house gases from the SUVs and sports cars will cause global warming on Mars (Marsal warming?), which will then teraform Mars to be habitable. We can then grow food on Mars and solve world hunger, on two planets no less. The end.
Granted, the religious fundies would just deny that we had ever been to Mars, or claim the oil was put there by god 5,000 years ago to test their faith. And there would have to be oil on Mars in the first place. And we’d have to figure out how to make SUVs run at several hundred degrees below zero with double the gravity. And I have no clue how fertile Martian soil is. But I can dream, right?
Or maybe we could just reproduce less.
