Harmful Algal Blooms ( HABS) Subteam

Harmful algal blooms (HABs) occur when simple photosynthetic organisms that live in the sea and freshwater grow out of control and produce toxic and/or harmful chemicals that harm land organisms, aquatic organisms, and ecosystems. The HABs in fresh and marine waters are usually very different, but they overlap in low salinity estuaries (places where rivers meet the sea). 

HABs have been reported across the world, and their occurrence is on the rise. HABs affect not only the health of people and marine ecosystems, but also the "health" of local and regional economies.

The HABs Team has members from around the country, and we welcome you to learn more by joining our Listserv:  To subscribe  click on this URL:  http://lists.sierraclub.org/SCRIPTS/WA.EXE?SUBED1=GN-HAB-SUBTEAM&A=1
