Here's some freaky news: According to United Nations, Earth's seventh-billionth person could be born by Halloween, even though "the fire marshal only certified Earth for 6,999,999," according to a recent tweet from "The Daily Show." It's a clever joke hiding a tragicomic dimension of the uncertain achievement: The planet's increasingly inhospitable climate and depleted resources mean we have little room for more humans, especially the 10 billion or more expected to stress the planet's already overweight system by 2100.
"Let's assume the average weight, or mass, of a human is 50 kilograms, or 120 pounds," University of Washington paleontologist and The Flooded Earth author Peter Ward told AlterNet. "That takes into account all the fat men, and all the kids, so it's a ballpark figure. That means 350 billion kilograms, or 770 billion pounds, of humanity on the planet. I wonder if this is the highest mass of any chordate on Earth. Only rats might weigh more of all natural populations."
But even rats have the good sense to abandon a sinking ship. Not so for humanity, whose resource wars have created a hyperreal dragnet that has caught up everything from mass-media distractions like Herman Cain and Mommar Gaddafi to worthy insurgencies like Occupy Wall Street. As those stories, for better or worse, dominated the news cycle, British Petroleum was quietly freed to resume drilling in the Gulf of Mexico after turning it into a marine nightmare since 2010. Exxon Mobil posted a $31 billion profit on the year thanks to billions in groundless government subsidies. American rivers and streams have become hypersaturated with carbon dioxide, and Arctic sea ice has become as thin as the United States is fat in the gut and head. Environmentalists and other concerned parties can be forgiven for not breaking out the bubbly because the planet has managed to spawn seven billion souls with increased life expectancy, thanks to miracles of science and industry. Because in the scariest scenario, that same science and industry could doom most, and perhaps even all, of us.
