And worried about carbon emissions -- not viral transmissions -- we were already wearing masks. The air was so choked by a plume of smoke that was so big that it reached as far away as New Zealand. Then in the midst o..

In the southern wetlands of Iraq, which are formed by the confluence of the Tigris and the Euphrates rivers, a unique, water-based civilization lives. For 6,000 years, the Maʿdān have floated villages on man-made isl..

01:00 A couple of years ago, I traveled to northern India to a place overlooking the plains of Bangladesh where the Khasi people live in a forest that receives more rainfall than anywhere else on earth.
