By updating the Toxic Substances Control Act (TSCA), Congress can create the foundation for a sound and comprehensive chemicals policy that protects public health and the environment, while restoring the luster of safety to U.S. goods in the world market.
Today, both business and government are constantly thinking about how to feed more people, power more homes and cars, and provide clean drinking water. But it is increasingly apparent that the use of our precious resources to meet one need is inherently linked to the the others in the food, water and energy “nexus.”
California, supplier of nearly half of all US fruits, veggies, and nuts, is on track to experience the driest year in the past half millennium. Farms use about 80 percent of the state’s “developed water,” or water that’s moved from its natural source to other areas via pipes and aqueducts.
Large river networks — such as those that funnel into the Colorado and Mississippi rivers — may seem to be permanent features of a landscape. In fact, many rivers define political boundaries that have been in place for centuries. Now researchers have developed a mapping technique that measures how much a river network is changing, and in what direction it may be moving.
Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to an oceanographer. In a study of the ocean’s role in the global carbon cycle, oceanographers used those nuggets to their advantage. They incorporated the lifecycle of phytoplankton and zooplankton — small, often microscopic animals at the bottom of the food chain — into a novel mechanistic model for assessing the global ocean carbon export.
Manure from livestock farms can be environmentally damaging. A new treatment system could clean up its impact, but will that just hide deeper problems in an unsustainable industry?
A survey conducted by Indiana University researcher Shahzeen Attari has found that many Americans are confused about the best ways to conserve water around the home. Her results have been published in the journal Proceedings of the National Academy of Sciences.
According to a Canada-U.S. environmental study released Thursday, an increasing amount of algae is sucking the oxygen out of Lake Erie, leaving a pungent smell and icky green water.
One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly?
Small fragments of plastic waste are damaging the health of lugworms, putting a key cog in marine ecosystems at risk. Published in Current Biology, a new study by scientists at the University of Exeter and the University of Plymouth shows the impact of microplastics on the marine worms’ health and behavior. By exposing specimens to contaminated sediment in a laboratory, the researchers were able to observe a 50 percent reduction in energy reserves and other signs of physical harm.
