Consciousness has the power to understand anything in existence when presented with the facts in context...
Humans possess consciousness, so there is nothing we can't understand once we figure it out...
In a couple generations after our population increases expodentially, we'll have filled the earth and be required to move elsewhere if no one dies to keep population stable.

Even if the population was growing exponentially, the technology to solve overpopulation "problems" would easily be invented...
Not exactly the best plan there. Also don't want to give immortality to elite, due to the fact it allows corruption to live much to long.
Only if corruption is allowed...
