There’s a growing idea out there that humanity is currently using up the resources of one and a half Earths each year, and that our ecological footprint is simply unsustainable. But according research reported in Real Clear Science, this guilt-inducing statistic is oversimplified, and ecological footprint measurements are so misleading as to preclude their use in any science or policy context. Perhaps most telling is that according to the studies, components like forests and farmland are doing just fine, but the one thing out of balance is carbon emissions. This means that once again, it’s the unproven threat of global warming that is rising to the surface, and allegedly throwing mankind out of ecological balance.
