The lack of limits on "limited resources"

First, from Spiked Online: Think the Earth is finite? Think again

Malthusians are simply wrong to say that resources are fixed, that we can measure and predict when they will run out. It seems commonsensical to say that the Earth is finite, and a bit mad to say that it isn’t, but it’s important to recognise how fluid and changeable resources are. It’s important to recognise that the usefulness and longevity of a resource is determined as much by us – by the level of social development we have reached – as it is by the existence of that resource in the first place.

Resources are not fixed in any meaningful sense. Resources have a history and a future, just as human beings do. The question of what we consider to be a resource changes as society changes.

A very early resource panicker was the second-century Christian philosopher Tertullian. In 200AD, Tertullian said: ‘We are burdensome to the world, the resources are scarcely adequate for us… already nature does not sustain us.’

But back then, there were only 180million human beings on the entire planet – about the same number that currently lives in the eastern part of the United States. The problem for Tertullian was his understandably limited imagination. In his time, pretty much the only known resources were animals, plants and various metals and minerals. Tertullian had no way of conceiving of the enormous abundance of resources inside the Earth, which lay dormant because of social limitations not natural ones.
