The fish weighed 615 pounds, and it surprised everyone since the elusive species has never been common in this stretch of river.

Humans, it’s no secret, are versatile and unpredictable in how they use their land. We build mega-cities in deserts, raise crops on flood plains, live along vulnerable coast lines enjoying seas dangerously rising, and burn rain forests to create new pastures.

Super Typhoon Haiyan left the central Philippines in ruins, with a staggering death toll that could climb well above 10,000. The U.S. military is leading the international response to the devastation, along with international aid agencies.

The people of northern Kenya currently face many daily hardships. Primarily pastoralists by livelihood, their cycle of life focuses on the basics – securing food and water for family and livestock, constructing shelter from the unforgiving sun, and finding sustenance when periodic droughts ravage the region. A 2011 drought affected millions of people, and tens of thousands of livestock died. Approximately 90 percent of the area’s population lives below the poverty line.
