What I've heard is that global warming is thought to be a major contributor to algal bloom in some Canadian lakes. Since loons hunt fish by sight, if they can't see to catch fish, they won't populate those lakes with algal bloom, thus squeezing them out of longtime habitats. cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
