Today is Earth Day, a celebration that's supposed to focus on attention on ecological balance — keeping our planet green and healthy. But as futurist Jamais Cascio points out in an essay published today, the point of environmentalism isn't to protect the planet — Earth has survived much worse than a little carbon emissions, thank you very much. Remember that asteroid that wiped out the dinosaurs? Way worse than aerosols in the atmosphere, and yet the planet survived. Cascio argues that the unspoken point of environmentalism is to save human civilization.
The fact of the matter is that, no matter how much greenhouse gas we pump into the atmosphere or how many toxins we dump into the soil and oceans, given enough time the Earth will recover.
But human civilization is far more fragile.
Human civilization could not withstand and recover from the same kinds of assaults the planet itself has shrugged off in eons past. We remain entirely dependent upon myriad Earth services and systems, from topsoil and clean water to carbon cycles and biodiversity. Activities that undermine those critical services and systems quite literally threaten the survival of human civilization. The fundamental resilience of the Earth's geophysical systems simply means that, when we ignore our effects on the planet, we're simply making ourselves disposable, just another passing blip in the planet's long history.
In trying to minimize the harmful impacts of human activities upon the global ecosystem, environmentalism supports the continued healthy existence of humankind.
Earth will be just fine, thank you [Open the Future]
