Do the maths.


Last year the Living Planet Report
(from WWF, the Zoological Society of London and the Global Footprint Network)
noted that human demands on natural resources has doubled in less than 50 years.


It projected that, if nothing changes,
we will need 2 Earths by the year 2030
to provide enough resources
to support the population.


There are over 6 billion human beings on planet Earth right now.
The United Nations expects the Earth's population to reach 9 billion by 2050
(population increases measured on current life expectancy)


We are now being told by scientists
that the life expectancy of human beings may double within our lifetime.


I can't make those figures work.

I thought they were predicting that our kids will be the first generation to have a shorter life expectancy than their parents (due to obesity, inactivity, etc, etc).

Either way, poor old Mother Earth has a tough gig.
