How long do you think human race will survive?

How long (using knowledge of science and about our universe) do you think the human race will survive?

• What technology should we invent to keep us alive

• Answer:

  Civilizations rise and fall, so it's a hard question to answer. Even in the event of a nuclear war, some will survive, and humans breed like rabbits. The only thing that would wipe out ALL humans, not just a large percentage of the population, is a global catastrophe, such as a meteor impact or epic size. All other issues are generally regional in scope, so some region of the globe will still harbor some humans. When will we be supplanted by a more advanced species? That is something that cannot be determined. Generally, the more complex the species, the less time it survives as a species. The same species of insects and microbes have existed for many millions of years, humans might make it another million, but by then they would not be recognizable as modern humans. They would likely be a different species. Life has a way of hanging on once it gets a foothold, in one way or another. When we damage the environment, what we are doing (besides wiping out much more fragile species) is endangering our own existence by changing the parameters under which we are used to living. Like I said, civilizations rise and fall, but life seems to be more tenacious.
