Pointless worry

A writer giving his book a plug in the Sunday Post noted that the track record of the dominant species on the planet is that they go extinct, and he shudders to think how long it will be before the current dominant species; humans; hits the buffers.
    If we can do as well as the dinosaurs, no need to worry. And it’s not too likely that a planet with another 5 billion years to go before its star goes nova and eats it up will be too bothered about losing another transient dominant species.
