Ecological restoration makes city dwellers happier and healthier. by Liza Lester, ESA communications officer IN the first summer after my move from the cool green climes of western Washington State to Washington, DC, I gained a primal, physical understanding the urban heat island effect. Summer in the District of Columbia is a hot, humid shock for a native northwesterner, and last summer was record-breaking hot. Cycling away on humid...

Water pollution turns microbes virulent

An idyllic lake turns threatening when heavy rainfall causes a sewage treatment plant to overflow. Within 24 hours, once-benign microbes turn into virulent pathogens, breeding incessantly and attacking the embryos of lake fish. As much as that may sound like the synopsis of a movie on Mystery Science Theater, this is an impact on lake ecosystems that is actually occurring. It is widely accepted that nutrient enrichment and pollution...

To fertilize or acidify? Nitrogen plays both sides in soils

The human industrial and agricultural sectors contribute to air pollution by releasing nitrogen oxides (sometimes denoted NOx) into the atmosphere. And just like ocean acidification occurs when carbon dioxide dissolves into the ocean, soil acidification can occur when nitrogen oxides dissolve into soils. But we also know that nitrogen is a major component of fertilizers, which add nutrients to soils.  So how do these two...
