| You see earthly stuff as a risk because all the positives are grandfathered in and you only see the negatives. Bats and pagolins, now are public enemy #1. In general animal reservoirs for viruses and species jumps can't possibly happen on Mars because there are no animals and no other specie. So we have eliminated that risk right? But....that also means no food, no ecosystem, no biosphere, basically absence of everything. So the benefits provided by bats , poultry, bovines etc. outweigh the negatives of a pandemic every 100 years or so Even an Earth ruined by supervolcanoes, mega asteroid, nuclear war and climate change all at the same time..is better than Mars. The only cases in which Mars comes out on top are a huge comet impact and a Gamma Ray burst which strikes the Earth but somehow misses Mars. Bezos is right saying that we have to go to space to save the Earth, then we can talk sci-fi type things such as mind uploading ourselves in silica, and once that process is complete than Mars and the Earth will be equally valid to host us. But that ship won't set sail for a long while. |
Right. But you have to start to be able to reach that point. And sooner you start - the sooner you will arrive to it.
