So what you're telling me is: we can still trash the fuck out of this planet, because we can just cannibalize resources from others. Fuck yeah no consequences *throws Styrofoam cup into the ocean as she speeds off in her Hummer*
But seriously, this is pretty sweet that we're finally able to really study the celestial bodies within our own solar system. I mean, how long have we been aware of them? And our technology has finally reached a point to where we can 'dig beyond the surface' so to speak. Re-evaluate facts that we THOUGHT we knew. And all within my (our) lifetime. Lucky us.
It's OK to have a sense of wonder, kids, people will still think you're smart.
