Global Threats: Water Scarcity and Uncertainty in the Estimates of Groundwater Availability
By Roberta Attanasio Groundwater is any water that lies in aquifers beneath the land surface. While some of the water that falls as precipitation is channeled into streams or lakes, and some is used by plants or evaporates back into the atmosphere, most of it seeps underground in the cracks and spaces present in soil, sand and rock. Underground layers of rock that are saturated with groundwater are called aquifers. The groundwater contained in aquifers is one of the most important sources of water on our planet, and can be brought to the surface through natural springs or by pumping. Groundwater is constantly replenished (recharged), as part of the natural water cycle,…

Global Threats: Climate Change is a Medical Emergency
By Roberta Attanasio For many years, we’ve been aware of the impacts of global climate change on human health and well-being. For example, safe drinking water, sufficient food, and secure shelter are threatened by rising sea levels and severe weather events. Heat waves dramatically increase death rates not only from heat strokes, but also from complications arising from cardiovascular, respiratory, and cerebrovascular diseases. However, the impacts of global climate change on human health are even greater than previously thought — according to a report published today (June 23, 2015) in The Lancet, the threat from climate change is so great that it could undermine the last fifty years of gains…

Neil Young, Monsanto, Starbucks, and “The Monsanto Years”
By Roberta Attanasio About two months ago, legendary music icon Neil Young announced the release of “The Monsanto Years“, which will come out on June 29th.

The North American summer tour dates for “The Monsanto Years” have also been released — the tour starts July 5th at the Marcus Amphitheater in Milwaukee, Wisconsin. Monsanto is a leader producer of genetically modified organisms, or GMOs. For years, Young has railed against…

Quality Water, Quality Life: Aquatic Health and Contaminants in the Midcoast Oregon Salmon Watersheds
A guest post by Ray Kinney From ridge tops to reefs, environmental degradation has caused many salmon populations to decline to one to ten percent of former numbers. Young salmon survival in freshwater is only 2 to 5% from egg to smolt phase just before entering the ocean phase of their life cycle. Many causative effects for this decline are known, but many remain to be clarified. Politics often prevents adequate investigation of contaminant effects for water quality. Chronic low dose accumulative effects of toxic contaminants take a toll that is generally unrecognized by fisheries managers. Our benevolent rainfall flows down out of the Coast Range to become, once again, part…
