Water covers nearly three-fourths of Earth’s surface, but most of it is salty or permanently frozen. Around 70 percent of the world’s fresh water is locked in the ice of Antarctica. Around 53,000 cubic miles of water passes through the planet's lakes and rivers, which are under constant assault from human encroachment. By the year 2025, 52 countries — two-thirds of the world's population — will likely experience water shortages, according to U.S. government data.
Fortunately, there are several organizations around the planet dedicated to conserving our rivers and preserving our future. Here are 10 images of some of the world’s most majestic rivers, and some ways we can help them thrive. Pictured here is the Lama River, located near Moscow. (Text: Katherine Butler)
