My footprint results

My Global Footprint
FOOD 3.2
MOBILITY 1.5
SHELTER 5.2
GOODS/SERVICES 4.4
TOTAL FOOTPRINT 14

IN COMPARISON, THE AVERAGE ECOLOGICAL FOOTPRINT IN YOUR COUNTRY IS 24 GLOBAL ACRES PER PERSON. WORLDWIDE, THERE EXISTS 4.5 BIOLOGICALLY PRODUCTIVE GLOBAL ACRES PER PERSON.
IF EVERYONE LIVED LIKE YOU, WE WOULD NEED 3.2 PLANETS.

I look at my results and by way of explanation I must admit that my transportation(mobility) is much lower than I had anticipated. One of the results of this study does not show the efficiency of my shelter. In many ways my dwelling unit (shelter) is the most efficient operating part of my profile and is not reflected in my profile. I am concerned that efficiency of an item is not considered. Also, it is surprising the a healthy food profile(local foods and farm purchases here in Virginia) do not reflect a better profile. In comparison a friend has two SUV's lives in a larger house and buys no local fruits, vegetables and meat and has the same total profile 14.
