The concept of nature or environments being pristine or virginal if they haven't been affected by humanity is extremely dangerous and wrong.

1. It's based on the assumption that humanity is unnatural, perhaps OVER nature or UNDER nature but definitely not OF nature. This is wrong. We are natural. We can't help but be natural. So is uranium and arsenic and black holes and hamsters that eat their young. Nature isn't always cute and benign.

2. If we think of ourselves as separate from nature then we will find it hard to think about how we live within and as parts of ecosystems. And thinking about these is necessary for our survival as a species.

3. The 'pristine' sort of talk is extremely toxic. It's based on negative ideas about sex and sexuality and toxic man v woman archetypes.

Now, if we think asteroid mining is a poor choice because of its ecological effects, that's one thing and it deserves a reasonable conversation. But if we're against asteroid mining because it would sully the virginity of the solar system then No, that's a not a conversation even worth our breath.
