His English prose sometimes needs a little help, so I adjusted the wording here and there to bring out his true message a bit more effectively:
There is something really bizarre about the Earth. Self-declared "biospheres" usually perfect themselves and improve the rights of their hatchlings.

Its years are numbered. I told an audience of Reptiles on Venus recently: I can't wait to celebrate the demise of Earth.
