Researchers have developed a method to estimate the value of oyster and clam aquaculture to nitrogen reduction in a coastal community. Nitrogen is a nutrient that comes from many different sources, including agriculture, fertilizers, septic systems, and treated wastewater. In excess it fuels algal growth, which can affect water quality and human health.
As a result, a growing number of communities are required to follow regulations to reduce the amount of nitrogen they release. Shellfish are an option that can be a valuable part of a community s nutrient management plan.
In a study in
Environmental Science & Technology, shellfish biologists, economists, and modelers from NOAA Fisheries, NOAA National Centers for Coastal Ocean Science, and Stony Brook University used a transferable replacement cost methodology to estimate the value of oyster and clam aquaculture to nitrogen reduction in Greenwich, Connecticut.

When we think of the devastating toll that plastic pollution can have, it is usually images of turtles caught in single-use bags or piles of plastic bottles in landfill that we conjure up for most of us, it is an environmental problem.
But there is emerging evidence that plastic waste could become a health issue, too.
The problem lies with plastic as it breaks down into tiny particles so-called microplastics, which are 5 mm in length (the size of a lentil), or less.
These tiny particles are everywhere: they are produced from the breakdown of bags and bottles, the wear and tear of the soles on our shoes as we walk, and the tyres on our cars as we drive.
