Think of this! If all seven billion people on Earth lived according to the average American, five planets would be required. Go ahead! Check it out! Go to the Global Footprint Network website and use their calculator. Of the many footprint calculators on the web, the Global Footprint Network sets the standard.
The network tells us that in order for all of Earth’s people to achieve the standards of European societies, as many as four planets are required. Or if you lump our species all together globally, from richest to poorest, then we demand 1.4 times from nature what she annually regenerates. This means that by early fall of recent years we began using resources beyond what Earth’s ecosystems produced in that year. I was shocked to learn of a study published in 2011 in the Marine Ecology Progress Series that determined we will need 27 planets by 2050 if we cannot greatly improve on what our living practices were in 2011. My mind stumbles before these impacts on Earth’s ecosystems from human population, overconsumption, and inefficient resource use. Our species, so capable of enormous good, continues to play in a high stakes casino game headed for self-destruction.
