Today marks the point when humanity as a whole has used up the resources needed to live sustainably for a year. The day is declared every year by Global Footprint Network, a nonprofit research group that focuses on sustainability. It’s been creeping up the calendar ever since, landing on Aug. 19 in 2014. And August 13 last year . So Cons and every one else, but Conservatives specially, will you stop driving gas guzzlers and limit your hunting, fishing and cutting trees for the rest of the year or no?
