The fact that a lot of current change is done by humans, may give it an air of artificiality, but to that idea I don't subscribe. Humans are still biological identies, and as such, need an ecology to survive in. 'Nature' or 'the world' does not care what particular ecology it sustains; as long as there is biological life, it exists, period.
Your premise that being self-aware is not a reason to colonise the solar system and then the galaxy is based on...what? I would claim it DOES (though it would not excuse us from being responsable - to alien life - while colonising).
If alien life is not omni-present on the planet, but only in small niches, I think it's worth considering to protect those niches, or create articial enclosures to preserve it - but still go on with the colonisation. Things would only be different if it's a planetwide alien ecology, or if there is alien sentient life involved.
