Sea Lions Dying at Increasing Rates In five months alone‚ over 3‚000 sea lion pups‚ at a point teetering towards death‚ washed ashore on Southern Californian beaches‚ fifteen times more than in past years‚ due to toxic algal blooms. Merriam Webster calls algal blooms‚ “rapid and excessive growths of a plankton population.” Since 1998‚ scientists have been aware of sea lions and their pups being intoxicated by domoic acids from toxic algal blooms. Agricultural and suburban areas are the main culprits

The sludge is largely converted to ’biogas’‚ a mixture of CH4 and CO2‚ which is used to generate electricity for the plant. The liquid is treated by bacteria which break down the organic matter remaining in solution. It is then sent to oxidation ponds where heterotrophic bacteria continue the breakdown of the organics and solar UV light destroys the harmful bacteria.

People with lung conditions are especially vulnerable as it can cause future complications in their condition. Not only does the toxin affect the air but it also affects shellfish that are being consumed. Shellfish are not affected by the toxins but they absorb it. When humans ingest infected shellfish they can get neurotoxic shellfish poisoning. This can result in the need of hospitalization fro anyone who has ingested infected

The cyanobacteria which are blue-green produce harmful toxins which have harmful effects on humans‚ birds‚ shellfish‚ fishes and other marine organisms. A few forms in which HAB’s can occur are red tides and golden tides. Red tides belong to a group of dinoflagelates and are produced by microscopic alga called Karenia brevis‚ and golden tides belong to the group

Although evidence has shown that there is a recent change in the increase of the cownose ray that has caused a large boom‚ it’s Well known that the cownose ray is a predator of shellfish when the water becomes warm. The marine systems caused by the removal of sharks remain misleading‚ due to the significant declines in large coastal sharks in the northwest Atlantic Ocean‚ which caused dramatic increases in abundances of smaller elasmobranchs (referred to as “Macropredators”) over the predation release
