But what are the ethics of this (the terraforming, not the eyeball thing)? What if Mars already contains hidden life? Might the origins of life on Earth trail back to the red planet as well? Thoroughly contaminate everything and we might erase all trace of what was. And the past isn't the only thing potentially at stake.
"Here's a deeper question," Brother Consolmango said. "What if there is no life on Mars or Titan or some other place we're going to go to, but all the ingredients are there, such that at some future time life could exist. The potentiality of life is there and, by terraforming it, we're aborting that possibility. Under what circumstances is that an ethical thing to do?"
What do you think?
In addition to covering these topics, Brother Consolmango also touched base on the issues of light pollution, meteorite collecting and the coexistence of science and religion. On the meteorite issue, I was pleased to hear him hit all the points I made in my recent post on the matter.
And you can read my HowStuffWorks.com blog post Can science and religion coexist? for more on the religion/science issue.
