This seems to be the final answer to the question, population: how many is too many?
The only flaw one could find in this challenging talk is that there was not much room for debate, since both the excellent speakers agreed that we are already too many. According to the most realistic estimations the planet would be able to sustain at most 2.5 billion people (living our unsustainable lifestyle).
Therefore, even assuming a drastic cut in our consumptions (by all means necessary), remains the problem of how to accommodate the 7 billion that since last year populate this planet?
We simply can’t. This was the first point that Jonathon Porritt wanted to stress: any serious discussion about sustainable development and consumption must address the population issue. It is something we can no longer ingore and Porritt finds particularly frustrating the almost total lack of references to overpopulation within environmental organizations, in which he has been working for years.
