I like your story but your second sentence is completely wrong.

" Our world, planet, biosphere, and human culture are complex and becoming steadily more so."

Our planet, biosphere and human culture are become less complex and steadily more bipolar.

Extinctions have simplified the biosphere, not in a good way but less species means less complexity. The magic is lost with the lose of this complexity.

Human culture is becoming more homogenized. Less black and white and more brown. Politic has become almost totally bipolar, us and them.

This is not to take anything away from your story, if you left out that flawed sentence your story would still stand complete.
