Earth at 8 billion: Consumption not crowd is key to climate

SHARM EL-SHEIKH, Egypt (AP) — The 8 billionth baby on Earth is about to be born on a planet that is getting hotter. But experts in climate science and population both say the two issues aren’t quite as connected as they seem. Sure, more people consume more energy and put more carbon dioxide in the air. But experts say it’s not a simple numbers game. The poorest half of the world’s population only produces 7% of the carbon emissions. Experts say it’s not the size of the population, it’s consumption or over-consumption. They say it’s not too many people, but rich people polluting too much.
