What’s your footprint?
How much demand does each of us put on the earth's ecosystems and natural resources? How much land and sea—cropland, pasture, forest, and fisheries—are required to produce the things we consume? And to absorb the waste we discard?
If everyone on earth lived like us, how many planet earths would it take to support all of humanity?
To compare our individual lifestyles and cosumption against nature's ability to provide for it, we can test our ecological footprints at any number of websites. One particularly good footprint website is www.myfootprint.org.
