Then find out how many earth's we would need to sustainably support humanity if everybody was the same.

I roll in at 2.9 global hectares, of which most of that is down to food. It's very good compared to the UK average which is 5.3hectares/person but unfortunately we would still need 1.6 worlds for it to be sustainable.

Its certainly food for thought.

Edit:

The FAQ is interesting reading too:

lol, "IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 2.2 PLANETS"
Thats a great site ;)

Isn't it :D

IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 4.2 PLANETS.

*walks away in shame*

IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 2.7 PLANETS.

Well thats depressing, I was expecting a lot higher.

2.3 planets for me. Oh well, I'm an improvement on the rest of you. [img]tongue.gif[/img]

"IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 1.4 PLANETS."

Eh? "We"? I'll be dead before we need another .4 of a planet!

I needed 1.8. I did it at school as well. But IIRC it was flawed cause of some questions.

2.2 planets, and most of it was probably the living space.

I can't but to wonder what this test really shows. Does it take into account hat you can use the same hectar in a energy efficient and non energy efficient manner?

According to this test, in order to get just one planet, you'll almost need to be 7 vegetarian people living in a 30 m² Green-design house with no electricity, and uses only your legs, a bicycle or some form of animal for transportation.

IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 6.4 PLANETS.

Earth first! We'll stripmine the other planets later...
