If every one in the world would live like me...

This entrance is about my ecological footprint in the world, and it consists in a calculation (that takes in account my life style, how much I travel, what do I eat, what do I buy, etc) that gives at the end how many worlds would the human population need (in means of natural resources) if everyone lived like I do.  
I did the excercise in the site:
http://footprint.wwf.org.uk/ 




And my result was:

My carbon footprint is 20.15 tonnes per annum

and if everyone would live like me, 3.88 planets would be needed.
