Invasive Weeds And Wildfire
August 14, 2007 08:27 PM - PR Newswire
Invasive plants systematically infiltrate millions of acres every year, selfishly soak up precious water supplies, forever alter wildlife habitats and quietly invade our backyards. In fact, the economic impact of invasive plants and weeds in the U.S. has been estimated at $34.7 billion annually, according to a recent Cornell University report.
Great Lakes Losing 2.5 Billion Gallons Per Day Due to Manmade Drain Hole Near Detroit
August 14, 2007 08:13 PM - Paul Schaefer, ENN
Research released Tuesday finds that a river "drain hole" on the St. Clair River is sucking away triple the amount of water previously estimated--causing widespread ecological harm throughout the middle Great Lakes. The updated findings released by the Georgian Bay Association (GBA) show that the drain hole in the St. Clair River is causing the Michigan-Huron system to hemorrhage 2.5 billion gallons of water a day--more than triple the 845 million gallons documented two years ago by a consulting firm studying the impact of the U.S. Army Corps's dredging in the river.
U.S. Ocean Policy Report Card
August 14, 2007 08:04 PM - John Tibbetts, Environmental Health Perspectives
If the U.S. government were a student, it would be on the verge of flunking Ocean Policy 101, to judge by the U.S. Ocean Policy Report Card issued 3 February 2006 by the Joint Ocean Commission Initiative. The United States has accomplished far too little in response to a health crisis in the nation's oceans, coasts, and Great Lakes, according to the report card. More than a dozen federal agencies have a say in setting and implementing ocean policy, and they often fail to work together. Policy makers need to repair this fragmented system of ocean governance, and they need to do it fast.

"Porous Paving" Prevents Pollution, Erosion
August 6, 2007 06:34 PM - Ecological Home Ideas.com
Avoiding solid - non-permeable - surfaces in driveways, walks and patios is better for the environment. Solid surfaces, such as driveways, walks and patios force storm water to run off and create a host of environmental problems. First, storm runoff can erode surrounding soil, damag lawns, wash away soil and cause flooding. Even more damaging, storm water can carry pollutants into sewer systems, surrounding waterways and water tables, posing serious health hazards.
