Said beaver dam is filtering a river bearing thousands of chemicals and substances foreign to it before man; is constructed of trees which flourish in the area because of man - where it isn't using outright man-made ingredients like plastics; and supports a pond with alien invaders or just smaller species (because of the excess heat caused by the lack of forest). And this isn't even trying very hard for examples of how even 'natural' features are unnatural and modified for our convenience. Radionuclides are a signature of man's presence that will never go away.

And what does dark energy and other fudge factors relating to the overall structure of the universe have to do with narrow models of stellar evolution and the inevitable supernovae of any stars over the Chandrasekhar limit? Either admit it's baseless speculation (and not even bad humor), or provide an example of a star blowing when our equations say it shouldn't.
