Mine came out so bad it's too embarrassing to post. But in my defense there are a lot of eco-friendly things I do that aren't reflected in the quiz (recycling that borderlines on being OCD, for example, and water conservation).
I'm still trying to figure out what caused my footprint. I use public transportation to get to work -- I only drive about 500 miles per month because of this. I recycle as much as possible. I donate clothing, furniture, and other items that I no longer use, etc.
Yet, I have a footprint higher than everyone who posted one so far. If I had to guess, it may have to do with the amount of business travel, via plane, that I do every year.
I came in at 2.6 earths on this site. I like earthlab better. They are more precise and granular. For example, they differentiate between short and long airline trips, have more types of residences and ask about the eco friendly things you are already doing. They also itemize where you footprint comes from. Like Henry, I got most of my footprint from flying. But they tell you, rather than having you guess.
didn't try earthlab yet. With ecofoot I had: Food1.5 Mobility0.0 Housing1.2 Goods / Services1.4 Total Footprint4.1 mean in country 8.4
Planets needed: 2.3 Ok, 2.3 planets, I think that's manageable. One in the trunk, and terraforming mars should do the job.
The test doesn't have a "high resolution" but can of course be a first hint. I didn't read the faqs of the site but surely agriculture has the biggest impact on the worlds terrestrial ecosystems, so my biking doesn't help here much...
In comparison, the average ecological footprint in your country is 5.3 global hectares per person.
If everyone lived like you, we would need 2.8 planets.
Like Henry, I use public transport, and drives less than 100 miles a week, which explains the MOBILITY 0.8. A lot of the food is processed, but its the packaging that annoys me the most! Milk cans for instance, in many parts of the world, including India, they are fine cans that can last many years to hold all sorts of liquids, where as I just have to toss them in to the bin! A times I wonder why governments wouldn't introduce a tax on milk cans and promote the older style milk bottles (but I am sure there is a good argument against this, like hygiene..)
