Most of the planet’s freshwater stores are found in the northern hemisphere, a region that is changing rapidly in response to human activity and shifting climatic trends. An international team of scientists analyzed 147 northern lakes and found that many rely on nutrients from tree leaves, pine needles, and other land-grown plants to feed aquatic life.
Rick Ostfeld and Felicia Keesing have been studying Lyme disease and ways to stop it for more than 20 years. The couple has come up with a way to predict how bad a Lyme season will be a full year in advance.
President Trump will sign an executive order Tuesday directing federal agencies to channel the wisdom of late Supreme Court Justice Antonin Scalia in reconsidering an Obama administration rule that expanded Washington’s jurisdiction over state and local waterways under the Clean Water Act.
The White House has decreed that for every new regulation enacted, two existing regulations must be nullified. Regulatory overseers are now assigned to every Federal agency that might consider adding a new regulation. What a mindless way to ensure the health and safety of society.
New York's Eric Schneiderman and 10 other attorneys general have sent a letter to U.S. Senate leaders. The letter urges opposition to a bill that would eliminate states' authority to protect waterways from ships' polluted discharges, making it easier for non-native species to invade the Hudson River and Great Lakes.
They may be down but they're not out: Damaging insects can emerge from fallen trees and logs for several years after a major storm, according to a U.S. Forest Service study that reinforces longstanding warnings against moving firewood from place to place.
When Scott Pruitt takes the reins of the Environmental Protection Agency, we can expect him to dismantle federal environmental protections. Among the protections that he would like to roll back is the recent rule defining the "waters of the United States" under the Clean Water Act. Repealing this rule would cut the heart out of the Clean Water Act, effectively handing our waters back to big polluters. This should be resisted.
Working independently, Likens and Scheffer have, says the jury, contributed to understanding and finding solutions for “gradual, abrupt and potentially irreversible ecosystem change” in response to pollution and other ecological threats. Together, the two scientists “have transformed our understanding of how human activities are changing the structure and function of natural ecosystems, and provided tools to inform ecosystem management.”
Despite a steady rise in the manufacture and release of synthetic chemicals, research on the ecological effects of pharmaceuticals, pesticides, and industrial chemicals is severely lacking. This blind spot undermines efforts to address global change and achieve sustainability goals.
Protecting the environment is usually easier to the extent we can link it to human health concerns. The tough federal Clean Air Act, for example, has been driving the Chesapeake Bay cleanup, but the real impetus for the law is the Environmental Protection Agency’s estimate that it’s saving more than 160,000 human lives each year.
Tis the season when many Americans welcome trees into their homes. For millions of us, fresh-cut evergreens are at the heart of Christmas celebrations – a symbol of hope and joy. Sadly, the situation facing America’s trees is neither hopeful nor joyous.
The scourge of forest pests is expected to put almost two thirds of America’s forests at risk by 2027, costing several billion dollars every year for dead tree removal and jeopardizing longstanding U.S. industries that rely on timber.
In a towering forest of centuries-old eastern hemlocks, it's easy to miss one of the tree's nemeses. No larger than a speck of pepper, the Hemlock woolly adelgid spends its life on the underside of needles sucking sap, eventually killing the tree.
