An imaginary scenario, if I may.

Before we became one world, one island has a relaxed and happy style of life and without them noticing it, at first, their population grows beyond what the island can feed.

Some say, slow down the birth rate

Some, kill all the babies for they are not people yet, until we are down to what we can feed - others counter, if we do so, the numbers we can feed will grow to a tenth of what it is, since soon almost nobody will be available for growing the food.

Others, look at the horizon and say, we must learn to build boats, for there must be other islands out there.

But, they are countered by those who angrily demand they only concentrate on healing and feeding everyone and forget this wasteful idea of travelling.

What a pity, said one person to himself, we do not need new medicines, we need more honest people in the medicine business (witchdoctors) and killing the babies is a bad solution, for it will kill what makes us humans, while exploring the seas, extending the frontier of our people will strengthen our spirits and maybe some good island will be found... but reason and ethics will be transformed to suit the wishes of each party, until we die out, or stop existing as people, and become feeble, unintelligent animals that know nothing about dreaming and growing.

The proponents of the theories of us devolving will win, for it means we do not have to struggle, make an exertion and risk failing.

Sigh. Maybe it is what we deserve?
