According to a new study, 42 percent of American adults will be obese by the year 2030. And all this week, The Takeaway looks at that prediction with people we might not normally think of as obesity specialists. Today, the conversation continues with Michael Moyer, senior editor at Scientific American. Moyer believes that in order to combat America’s obesity epidemic, the answer isn’t mere math equations.

Fifty years ago, five countries created an economic consortium to control the price and flow of crude oil: the Organization of Petroleum Exporting Countries. OPEC's birthday comes around the same time that a new paper by a German military think-tank sheds light on how close the world is coming to the potential moment of "Peak Oil."

All week long, in partnership with our friends at Scientific American, we’ve been talking about "the end" on The Takeaway. The end of the world, the end of our own lives, or, today, the end of things that we could do without.

From Daylight-Saving time to the Space Shuttle, landfills to human drivers, we talk to Scientific American editor Michael Moyer about an eclectic mix of things that the world — and humans — might be better off without.

What do you think? What are some of the things we'd be better off without?

Is it the end of the world as we know it? This year, we’ve seen terrible flooding, glaciers melting, and deep oil wells breaking. In light of these catastrophic events, we're launching a series this week about whether our modern age is coming to an end along with our friends at Scientific American.

For the first installment of the series, we talk with Michael Moyer, staff editor for Scientific American, about the world's dwindling resources. He recently wrote about this in his article, "How Much is Left?"
