GR:  Why don’t conservationists give up their pleas for river ecosystems.  After a century of effort, they should have learned that investors will do nothing that might jeopardize profits.

From Science Policy Forum:  “The world’s most biodiverse river basins—the Amazon, Congo, and Mekong—are experiencing an unprecedented boom in hydropower dam construction. These projects address important energy needs, but advocates often overestimate economic benefits and underestimate far-reaching effects on biodiversity and critically important fisheries.

“We call for more sophisticated and holistic hydropower planning, including validation of technologies intended to mitigate environmental impacts.” –Authored by 38 scientists.
