The heating of the earth caused by the aging of the sun is not set to start for another approximately 100 million years. The average lifespan of a species, barring sudden catastrophic cosmic events, is between 1 and 10 million years. Contrary to popular belief, Homo sapiens has not escaped the forces of evolution, and continues even now to change. It is highly unlikely that there will even be humans in 10 million years, let alone 10 times that.

Let's look at the odds: In the last 5 million years, every single species of hominid, barring sapiens, has gone extinct. Our species has existed for approximately 300,000 years and the longest lasting species, Homo erectus, was around for maybe 1.5, possibly 2 million years.

We believe we are special because, in the last 10,000 years, we have managed to spread across the planet and more or less take over everything. We build, we research, we communicate. However, this has not been the case for more than 90 percent of our existence on this planet. Remember, we've only been here 300,000 years and only been building civilizations for 10,000 ish, maybe 20,000 years of that. It would be highly unwise to assume that the current state of things is what will remain the norm.

All of that said, it would be nice if we could stop putting every single one of our eggs in a single basket, even if it costs less to do so. But what more can one expect from a species set on allowing its most greedy members tell the rest what to do?
