Thousands of hydroelectric dams are under construction around the world, mainly in developing countries. These enormous structures are one of the world's largest sources of renewable energy, but they also cause environmental problems.
Only a little more than one-third of the world's 246 longest rivers remain free-flowing, drastically reducing the diverse benefits that healthy rivers provide to people and nature everywhere, according to a new study by World Wildlife Fund (WWF) and partners.

Violence in the Brazilian countryside is on the rise. In the last two weeks, Amazonia has seen an alarming increase in targeted killings, with three massacres and at least nine deaths. The Catholic Church's Pastoral Land Commission (CPT) defines a massacre as a killing involving three or more people.

More than 16 feet long and weighing up to 1,100 pounds, Chinese sturgeons are among the world's largest freshwater fish. They're big and they're ancient. According to fossil records, they've been swimming China's Yangtze, Qiantang, Minjiang and Pearl Rivers since the time of the dinosaurs.
And now they're on the brink of oblivion, having disappeared from all of their former range except for small portions of the Yangtze.
This year's Living Planet Report shows that populations of animals—including mammals, birds, fish, reptiles and amphibians—plummeted by 60 percent between 1970 and 2014. But those living in freshwater are experiencing a far more drastic decline: 83% since 1970. It's a sobering statistic and one tied directly to the ever-increasing pressures that people are putting on natural habitats.
The ailing orca whale J50 was declared "missing and now presumed dead" by the Center for Whale Research Thursday, after a three-day search by the organization in the waters between Washington state and Canada failed to locate her.
She would be the third Southern Resident killer whale to die since June, bringing their numbers down to 74.

Flooding in India's southern state of Kerala has killed 39 and left more than 60,000 homeless as of Monday, The Times of India reported, in what India Today called the region's "worst flood crisis" since 1924.
Kerala, a popular tourist destination, has already seen heavy flooding this monsoon season, but the most recent inundation began last Wednesday, relief commissioner P.H. Kurian told CNN Sunday. The rains were so heavy that they forced authorities to open the shutters of a large number of reservoirs Friday to relieve pressure and prevent collapses.
