This is the most shocking, infuriating, and meaningful conclusion I have maybe ever seen:
The new Living Planet Index report from the World Wildlife Fund opens with a jaw-dropping statistic: we’ve killed roughly half of the world’s non-human vertebrate animal population since 1970.
The WWF data show that the species declines vary by habitat and geographic area. Tropical areas saw greater declines, while temperate regions – like North America – saw lesser drops. Habitat-wise, land and saltwater species saw declines of roughly 39 percent. But freshwater animals – frogs, fish, salamanders and the like – saw a considerably sharper 76 percent drop. Habitat fragmentation and pollution (think algae blooms) were the main killers of freshwater species.
The declines are almost exclusively caused by humans’ ever-increasing footprint on planet earth. “Humanity currently needs the regenerative capacity of 1.5 Earths to provide the ecological goods and services we use each year,” according to the report. The only reason we’re able to run above max capacity – for now – is that we’re stripping away resources faster than we can replenish them.
This is a model, so I don’t know how much faith to have in the specific percentage. But it is the clear and obvious trend, and its implications for life on the planet, that should slap us in the face, wake us up, and get us thinking about how to entirely re-invent human culture, human lifestyles, and the global economy.
The way in which the ever-expanding human presence on the planet is devastating the natural world and the biodiversity that we should be nurturing (instead of destroying) should be the number one preoccupation of humanity. It should be treated with greater alarm than Ebola, Al Qaeda, ISIL, and the Kardashians.
Put the arcane and petty religious disputes aside. Put the shortsighted and endless warring aside. Put intolerance, self-interest, and callous disregard aside. Put rampant self-gratification aside. And focus on the fact that we can’t think the way we think, and live the way we live. Everything must be questioned. Everything must be changed.
