People on this planet are producing ten times more nitrogen now than they did a century ago, and some of it ends up in far-flung lakes where it alters aquatic ecology.
Half the culverts placed in creeks of Alberta's boreal forest hang in mid-air, preventing fish from travelling upstream.
Most of the sediment from forest harvesting that ends up in creeks used for domestic water in British Columbia's Kootenay region originates from logging roads.
The first quantitative analysis of published studies on ultraviolet-B (UVB) radiation and water-borne life reveals that UVB causes widespread and devastating damage throughout aquatic ecosystems.
Clearing forests to grow crops has added to the amount of water that runs off of land into rivers by 2.5% in North America and 6% in Asia over the last three centuries.
The world has 307 million lakes, according to calculations made by an international team of scientists.
By building large, engineered dams, humans have added over half-a-million artificial lakes to the world's surface.
