Ecological Footprint

My ecological footprint said it would take 8.4 Earths the first time I took it, but then I forgot about the rest of the information, redid it, and somehow ended up with 6.6 Earths. So, my data on the 6.6 Earths try was, 29.2 global acres to support my lifestyle, 33.9 tons of carbon dioxide, and services was the highest % with 27.
