According to a 2008 study (Jelks et al), nearly 40% of freshwater species in North America are either at risk of disappearing or have already vanished. Representing some 761 distinct species, 230 are deemed “vulnerable”, 190 are threatened, 280 are endangered, and 61 are extinct (or extinct in the wild). These numbers represent a 90+% increase over a 1989 assessment of freshwater species. And these trends are consistent with assessments in Europe.

Croatia and Hungary signed an agreement yesterday to protect a major biodiversity area that crosses borders along three rivers. The agreement is being called a “Trans-Boundary UNESCO Biosphere Reserve” and has resulted in the World Wildlife Fund (WWF) awarding the two countries with a “Leaders for a Living Planet” award.

The reserve will preserve several endangered species, among other environmental jewels. There is also the possibility of the reserve expanding several times over into neighboring countries in the future.

A professor and student team have designed a network of modular floating docks to harness clean energy for New York City.

The eco-docks would generate the energy by harnessing tidal power from the city’s rivers; they should also help to add much needed green space above the dirty waters.

A new drilling study has definitively dated the Amazon River at over 11 million years old, and it has held its current form for at least the last 2.4 million years.

The Amazon is one of the two longest rivers in the world, and its flood basin is home to one third of all the species on Earth. Discovering the river’s age is a stark reminder of just how ancient and intertwined the Amazonian ecosystem is, including the immensely rich biodiversity which calls it home.

In a memorandum issued last Thursday, Lisa P. Jackson, Administrator of the U.S. Environmental Protection Agency (EPA), stated that “water in the United States is not meeting public health and environmental goals. Too many of our streams, lakes and rivers do not meet our water quality standards.”

Do you have a rain barrel for your home?

More and more homeowners are using rain barrels to conserve water while collecting soft, non-chlorinated rainwater to nourish grass and plants.

This weekend, in Calgary, Canada, Clean Calgary Association, in partnership with the City of Calgary, will hold its 8th Annual Rain Barrel Sale.

With spring coming, local residents there are thinking about their lawns and gardens. Water usage in Calgary doubles in the spring and summer due largely to lawn irrigation.

A well-respected Indian scientist nearly died after a 38-day hunger strike in protest of construction on a hydropower dam on a tributary of the Ganges river.

AD Agarwal, a 77-year-old former professor at the Indian Institute of Technology Delhi at Kanpur, began his strike last month when the Indian government refused to study the impacts of the dam before beginning work. The Ganges river’s free-flowing abundance is sacred in Hindu culture.

Are you looking for a community, environmental project for your family?  Keep America Beautiful is launching its 2009 Great American Cleanup today with its campaign “Green Starts Here”.

The Great American Cleanup begins today with a national launch event in Waveland, Miss., which will help  restore a hurricane-ravaged town along the Gulf Coast. It will continue through May 31 with additional national events being held in New York City on Earth Day and Nashville on May 14.

Millions of volunteers will work to rid streets, waterways and public spaces of litter and illegal dumpsites.  Communities will green up parks, schoolyards and other public spaces and hold recycling drives and educational events.

In the Napo region of northeast Ecuador, the nation’s second largest oil pipeline leaked tens of thousands of gallons of crude oil.

The pipepline company’s website described the leak as being due to ‘natural causes’.

American environmental scientist Douglas Beltman witnessed the amount of oil in the Santa Rosa river in the area and was quoted in a Reuters update, “The river was completely covered with oil from bank to bank.” (Mr. Beltman was generous enough to provide some photos taken of the spill for this story.) About 100 workers are cleaning up the area and a spokesperson for the pipeline company, Oleoducto de Crudos Pesados Ecuador, said the leak had been contained.

Gooey melted cheese on pizza, a glass of cold milk with freshly baked cookies, ice cream on a hot summer day… who hasn’t at one time or another enjoyed something made from milk?

Dairy products are part of most American diets on a daily basis, but what is the health and environmental impact of this high demand for milk?

The production of much of the milk in this country is done in large scale-operations, some having thousands of cows.

That’s a lot of manure to be dealt with, this reduces the air quality (especially for people living near the dairy operation), and consistently finds its way into our rivers, streams, and groundwater.

Tibetan glaciers are melting faster than predicted. Nearly a sixth of the world’s population, one billion people, directly depend on the glaciers for survival.

The Tibetan plateau has an average height of 14,000 feet above sea level. It is also home to over ten thousand glaciers. This gargantuan network of ice feeds some of the longest rivers in the world: Salween (2820 km) Mekong (4880 km) Yellow (3180 km) Yangtze (6380 km) Indus (3180 km) and Brahmaputra (2900 km).

Seasonal glacial melting provides vast quantities of water to these rivers and their watersheds. It is critical to all life there. An Ohio State University researcher named Lonnie Thompson, who has studied the region, is very concerned global warming could cause the glaciers to shrink below levels that currently support the local ecosystems, and human communities.
