Eutrophication can have serious, long-term effects the most notable effect of eutrophication is algal blooms when a bloom occurs, the stream, river, lake or ocean becomes covered with algae. General effects of eutrophication algae differ from microscopic animal life in our water bodies in their mode of respiration: they release more oxygen during the day than they use, and absorb more carbon dioxide than they release, while animal and other non-photosynthetic organisms release carbon dioxide and absorb oxygen from their environment. Algae are emerging to be one of the most promising long-term, sustainable sources of biomass and oils for fuel, food, feed, and other co-products what makes them so attractive are the large number and wide variety of benefits associated with how and where they grow. Now algae does not live very long, and so the top layer dies and sinks to the bottom and the next layer forms on the top of the lake first of all the algae layer on the top of the lake is cutting. 5 environmental effects as with production and use of any fuels, aspects of biofuel production and use have benefits and adverse effectsthis chapter discusses potential environmental effects from the production and use of algal biofuels, the potential influence of perceived or actual impacts on societal acceptance, and some of the health impacts potentially emanating from the specific.
