I do have a special weakness for deep future speculation inspired by a lifetime of reading SciFi. It brings a little perspective to present day here and now issues. The problem is that my consciousness won't see any of it.

So what might the Earth look like in a couple of hundred thousand years? From the perspective of whatever hominids are still around; assuming they are still around.

If 200,000 years (Homo Sapiens) is too near term, how about 2 million (Hominids), or 20 million (Primates)?
