Here is the article mentioned in the comment to Nicholas Kristof’s good news.
“The size of Earth is enormous from the perspective of a single individual. Standing at the edge of an ocean or the top of a mountain, looking across the vast expanse of Earth’s water, forests, grasslands, lakes or deserts, it is hard to conceive of limits to the planet’s natural resources. But we are not a single person; we are now sevenbillion people and we are adding one million more people roughly every 4.8 days (2). Before 1950 no one on Earth had lived through a doubling of the human population but now some people have experienced a tripling in their lifetime (3). So many people now inhabit the planet with so much impact that scientists have coined a new word to describe our time, the Anthropocene Epoch (4).”
