We have called ourselves Homo Sapiens - humans with knowledge. Our analytical ability is astounding. We understand matter right down to the level of quarks and mesons. We understand life right down to the function of individual genes o our DNA. We are very smart and clever.
We understand mathematics (or at least, some mathematicians do, fully). A GCSE student can understand that a doubling series tends towards infinity, and that the world is finite.So we should be able to understand that the human population of this planet cannot continue to increase exponentially.
But if you dare to mention this fact in a discussion, especially on the web, you will be called a fascist, and eco-fascist even, because there is an assumption that there is a human right to have precisely as many children as any given human wishes to have.
Oddly, the conservative right whingers who are most critical of the lumpenproletariat who sit at home watching daytime TV and adding a new child to their family every 9 months are among those most likely to shout "eco-fascist" at anyone who dares to mention the incompatibility of exponential growth rates and a finite planet.
I simply do not care. For humans to avoid global catastrophe it is necessary for us to apply our reasoning function to our own behaviour. Human population growth will inevitably stop at some time in the future, through one of three causes:
- Disaster, as our numbers outstrip the ability of the planet to sustain us, and we begin fighting over food.
- Compulsion, with baby licences and forced sterilisations.
- Education, whereby every human on the planet is informed of the facts, and persuaded to limit their family to two (and even that is too much, but less is impractical).
I have developed these ideas here in a linked series of posts.
