We're pretty special, at least in the context of this planet. Science tells us that we are by far the most intelligent creatures to live on Earth in its observable history, and the only ones to meaningfully modify it.

In the very least, we are the only creatures to inhabit Earth, that if we become extinct, it is somewhat likely that we are both the victim and the perpetrator.

We're hoping to start a colony on Mars. How could we possibly make Earth even remotely as inhospitable as Mars? Do you expect us to remove all the oceans' water? Remove most of the oxygen from the atmosphere? Kill all plants? I don't think we have much hope of making Earth inhospitable to us even if we tried.

Perhaps we somehow contaminate it all with nuclear waste. Even then, there'll be safety underground for long term living, relative safety even in contaminated areas for short term work, and radioactive water can be cleaned by distillation, mechanical or chemical means. We might have to set up a lot of infrastructure to do all that, but we've done a good job of setting up far more complex infrastructure already. It took only a couple of hundred years since the beginning of powered machines to get to where we are now. We could do it all again many times over in the next 10,000 years.

Perhaps they are extinct because we've been erasing them as we reformat the earth to be more congenial to ourselves? Their extinction is not a signal that we may go extinct ourselves; just the opposite.
