According to the U.S. Environmental Protection Agency (EPA), incidences of skin cancer in the United States have reached epidemic proportions, with one in five Americans now developing the disease in their lifetime. The National Cancer Institute reports that cases of melanoma, the most serious form of skin cancer, increased faster than any other cancer among Caucasians in the U.S. over a recent 20-year study period.
While tour operators and travel agents around the world may tout their trips as “eco-tours,” environmentally conscious travelers take a variety of considerations into account when determining whether or not any given excursion qualifies as such.
For 20 years now, the organization American Rivers, in its annual “Most Endangered Rivers” report, has highlighted rivers around the U.S. that have the worst chronic problems in need of attention. This year the organization took a new approach and focused on those “facing the most uncertain futures.”
Spray insulation is commonly used to fill spaces in unfinished walls, attics and floors. Most of it is made from polyurethane and “closed foam cells,” which means it forms a nearly impenetrable barrier. The material is widely recognized as a highly efficient insulator, effectively reducing heat transfer.
How are coral reefs faring around the world?
Aluminum can be toxic if ingested in large amounts, but there is no evidence that it causes health problems through the kinds of minor skin or airborne exposure one might receive from a window frame. As such, aluminum window frames are certainly healthy alternatives to fiberglass or vinyl,
Indeed, the glaciers for which Glacier National Park is named are melting away due to increasing global temperatures in recent decades, attributable most likely to global warming. A century ago, Grinnell Glacier, once the park’s largest, covered almost 440 acres. Today it has shrunk to just a quarter of that size.
cut flowers are one of the world’s most pesticide-intensive crops. Flower workers, of which there are roughly 200,000 worldwide, pay the heaviest price.
Why are so many environmentalists against nuclear power when it’s a reliable way to get emissions–free power 24×7 (unlike solar and wind)?
When forest fires occur, they can release significant amounts of gases and soot particles (known as “particulate matter”) into the atmosphere, where wind currents can then carry them great distances across major water bodies and national boundaries.
