Earth Overshoot Day 2016 lands on August 8, marking the date when humanity has exhausted nature’s budget for the year, as measured by the Global Footprint Network. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere -- we will be operating in overshoot. If that's not bad enough, the exhaustion of our annual ecological budget has been moving progressively earlier every year. Stephen Watson, the Director of Corporate Engagement at WWF-International joins us to tell us more.
