Why is it that when humans do our thing, we destroy nature instead of making it "better?"
The mind and free will were my initial thoughts as well, but upon further reflection I think not.
I personally believe that the differences between humans and the other beasts is quantitative not qualitative. That is, I believe animals also possess minds and have the capacity for free will and love. However, I would argue that their minds are not as complex as ours and thus their ability to express free will and experience love is not as rich as ours.
I think the human ability to destroy nature has to do with technology and
scale. Many other animals on Earth use tools (technology) including fish, but, again, the capacity of humans to use technology is currently unrivaled on Earth. However, that in and of itself is not what leads to destruction, it's the scale at which humans use technology. Because of our use of technology, humans have been able to conquer the globe and populate the Earth unlike any other large-bodied creature.
It is our large scale use of technology which is destroying the planet.
Why is this opposed to mind, free will, and love? Because if
wolves had the same capacity to use
technology on the same
scale as humans to do what wolves do - kill and eat other animals - I believe it would have the same resulting destructive impact on the Earth.
Obviously, this is an absurd analogy and difficult to wrap one's mind around. And humans use technology destructively for more than just killing animals, as wolves might do.
My ultimate point is I don't think human nature is quantitatively different from other animals; it's the ability (via technology) and scale at which we enact our will that is so destructive. If any other Earth creature had the same ability to enact their will at the same scale we do, it would likely be just as destructive.
(Also, our ability to use technology is a
result of our intelligence. So you could argue that ultimately it's our relatively advanced intelligence that leads to our destruction of the Earth.)
On the other hand, maybe not. Maybe there is something inherently
evil about the simian mind...
You have a very romantic view of humanity's role/position in reality. I'm not so romantic nor anthropocentric (or at least like to pretend I'm not).
I'm not sure humans are
destined for anything. (Life on the other hand is a different story...)
It's possible that humans can be most accurately compared to a virus or even a forest fire. Perhaps our
global role is to purge the Earth. Mayhaps ever million years or so a species arises on the Earth (and other similar planets) and manages to reduce the place to a pile of plastic baggies and empty soda cans. And then the process (whatever that is) starts all over again.

[W]hat I remember of The Spread of Excellence is that life doesn't necessarily get more complicated it just adapts...
@boomrang:
The theory that previous hominids may have had larger and more complex brains than ours is a new one for me and sounds interesting.
The Scientific Consensus is that life/organisms adapt to the environment. Sometimes this means life becomes more complex, sometimes less.
However, I agree that viewed pragmatically, life certainly appears to have gone from "less" complex to more complex. (Although to call even a single-celled organism
less complex given our current, limited understanding would be an act of hubris).
Anyhow, it's possible that the advent of technology externalizing intelligence (language and writing) meant it might be less adaptive for humans to have larger brains and thus more intelligence. So humans today are not as "smart" as past humans because we rely more on external technology.
