California's water supply depends on a clean snow pack and healthy mountain lakes. The lakes receive a large amount of runoff in the spring from the melting snowpack. If the snowpack is polluted, the lakes will be polluted.
Debris from forests that washes into freshwater lakes supplements the diets of microscopic zooplankton and the fish that feed off them – creating larger and stronger fish, new research shows.
For more than 40 years, policy makers have been working to reduce acid rain, a serious environmental problem that can devastate lakes, streams, and forests and the plants and animals that live in these ecosystems. Now new ...
The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record.
The space rock that smashed into Earth 65 million years ago, famously wiping out the dinosaurs, unleashed acid rain that turned the ocean surface into a witches' brew, researchers said Sunday.
Calcium can do much more than strengthen bones. The mineral is a critical nutrient for healthy tree growth, and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the ...
A team of University of Texas at Arlington biologists working with the U.S. Geological Survey has found that watershed wetlands can serve as a natural source for the improvement of streams polluted by acid rain.
A collaborative project involving a Kansas State University ecologist has shown that the Clean Air Act has helped forest systems recover from decades of sulfur pollution and acid rain.
Potential asteroid impact on Earth can have disastrous consequences. In order to prevent such collisions, earthbound space objects must be deflected. This can be accomplished using a space probe to impact the asteroid.
In the 1970s, red spruce was the forest equivalent of a canary in the coal mine, signaling that acid rain was damaging forests and that some species, especially red spruce, were particularly sensitive to this human induced ...
