Environmental Footprint

After taking the survey online, I found out that it would take 4.7 Earth's to support an entire world full of Sydneys. A footprint is the mark you leave on the world and is based on the way you live and treat our planet. To most people the measure doesn't impact them at all. To some however, it changes their day by day use of resources and alters their lifestyle. People change to more ecofriendly light bulbs, reusable drinking cups, or even  alter the way their houses use electricity. The thing I think I can change is by using a reusable cup. I don't own one, and even though I always recycle I think it would be way better to rewash one cup instead of having someone else break down a bottle and create something else out of it.
