Only two kinds of plants really thrive in today’s world: genetically altered crops, and really fast-moving weeds. So our world is all bamboo and kudzu now, it has nothing to do with the endangered foxglove lady’s slipper and its precious niche on some forgotten mountain.

That’s the truth you asked me for. That is reality. Paying tons of money to preserve bits of Humpty Dumpty’s shell is strictly a pious gesture."
