According to a BBC article, the world's human population is expected to hit 7 billion in the next few weeks. Link: http://www.google.co.uk/url?sa=t&rct...42080656,d.d2k
There's stuff here, too: http://populationmatters.org/
Apparently, (according to the UN) the world's population has risen from 2 to 7 billion in the last 85 years, and it seems fair to assume - the higher the population - the faster the population growth.. At the time, there was some talk that a population of 6 billion was unsustainable. So, as we pass through 7bn on the way to 8bn, and beyond - what do people make of it all?
I watched a David Attenborough program a few months ago that looked at population growth. He's a big advocate of population control.
Basically a population of around 20bn is sustainable on earth - if we all live like the average Rwandan. However, if the whole population lived like the average american (who i think live around 5-times out of their means) then you're looking at a population of around 2-3bn.
I think the average British person consumes around double their fair share of the planets resources.
...makes you think what would happen if we cured all diseases and stopped people dying of hunger, etc. We'd soon be fucked.
