Planetary Ecosynthesis on Mars and Geo-Engineering on Earth: Can We? Should We? Will We?

  • Christopher P. McKay


Environmental change on the Earth is imminent from anthropogenic causes and will also occur on a longer timescale from natural climate cycles – such as ice ages. These changes makes geo-engineering of the Earth inevitable. The question is not if, but, when and how. Planetary ecosynthesis on Mars seems to be possible, but is not inevitable yet that there are many reasons for doing it. A habitable Mars is not a "lifeboat" for the Earth, but it may provide deep and useful insights in the workings of biology and biospheres.
