This is satire. We’re not like the Magrathean designer world – builders in Hitchhiker’s Guide to the Galaxy – Nowhere as advanced – But maybe it’s time to look to Mars, Europa, Titan, Enceladus to continue our journey in case something renders Earth completely uninhabitable. The only drawbacks are :
The lack of a magnetosphere on Mars to shield would – be colonists from radiation. They’d have to live beneath domed complexes or under the Martian surfaces or within crater walls. It would be a monstrous task terra – forming a planet sans magnetosphere.
Europa – Possible ocean beneath the ice, but otherwise non Earth – like.
Titan – Resembles Earth with a primordial ocean – of methane.
Enceladus – Icy, possible tenuous atmosphere
We could still live on these worlds, but not without transplanting oxygen – generating flora, possibly for use as a food source. Vegetarianism would likely be a lifestyle beyond Earth. Or production of a product like Soylent Green. 🙂
Terraforming these worlds would be dicey for the immediate future. & forget Venus. It would be hard to live on, much less terraform, a giant ball of lava covered by layers of carbon dioxide. Mercury, MAYBE.
Is it too late for the Earth as we’ve known it? Maybe it’s time to start thinking of building an Earth 2.0, suggests satirist Jon Methven.
