Harvard’s modern-day Darwin warns against humanity’s downward slope

The Harvard University scientist who has called for setting aside half the planet as a nature preserve says the slope of human history will always be downward unless there is global cooperation to save existing species. Edward O. Wilson, a 92-year old naturalist hailed as the Darwin of the 21st century, said humankind is not too polarized to save the planet, even as some of the world’s biggest polluters drag their feet on cutting carbon emissions and arresting global warming. He sees preventing catastrophic climate change — the aim of U.N. climate talks starting in Scotland on Sunday — and saving biodiversity, or the variety of plant and animal species in the world, as two initiatives that must happen together.
