PAWLEYS ISLAND, S.C. — A new United Nations report projecting the extinction of one-eighth of all animal and plant species should rattle the cages of any remaining skeptics regarding climate change and the central role humans have played in Earth’s accelerating destruction.

The report is by far the most-depressing and frightening bit of news among an exhausting list of dire predictions and seemingly incessant fire alarms, from threatened increases to U.S. tariffs on Chinese imports and market plunges to North Korea’s missile tests and President Trump’s affronts to the Constitution. Just when you thought you couldn’t take any more.

Finding out that 1 million species face extinction without radical, corrective changes in human behavior is akin to finding out you have a fatal disease. One day you have a thousand problems; the next, you have just one.

The four horsemen of the Apocalypse — generally considered to be Conquest, War, Famine and Death — weren’t far off the mark. Today, we might revise the New Testament version to include Plastics, Emissions, Deforestation and Homo Sapiens.

It’s time to change our habits and, pending a better cliché, save the planet. It’s dying and we’ll die with it, eventually.

The report, a summary of which was released Monday by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), was the result of a three-year study by 145 authors from 50 countries.

Robert Watson, a British chemist who served as chair of the panel, wrote in a statement that “the health of ecosystems on which we and all species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide.”

But, Watson also said, it’s not too late to repair and sustain nature — if we act now in transformative ways. It won’t be enough for individuals to recycle their Dasani bottles or tote their own shopping bags, though these are helpful and keep us mindful. But big companies have to sign on and governments have to create incentives and policies to advance sweeping change. Needless to say, this won’t be easy.

In certain quarters, resistance to policy and procedures will be seized upon as a noble counter to regulatory zeal. Already, some so-called “conservatives” are gearing up to treat the report as a globalist attempt to hinder America’s return to greatness via more burning of fossil fuels, drilling for oil offshore and declassifying conservation areas. But conservatives by definition should lead the imperative. To conserve what is good — isn’t that the point?

Who knows? The end of the everything may be the great unifier we’ve been looking for.
