Eutrophication in aquatic system is the proliferation of undesirable algae excessively by the influence of enriched level of nutritional elements. It may occur naturally and anthropogenic influences. Literature survey reveals that large numbers of undesirable consequences are there in course of eutrophication which has been termed as pollution menace because of reduction of ecosystem services with increase in biomass, decrease in biodiversity, appearance of anoxic state and unhygienic situation and also fish killing. But in the present study it has been highlighted that this could be thought of as very essential phenomenon that acts as benediction of nature to the biotic life of this earth. All these adverse effects in eutrophication are favorable for the process of carbon sequestration that reduces the green house gas content in the atmosphere, keep oxygen-carbon-dioxide balance and control climate change. In anoxic state, the rate of microbial degradation of organic matter decreases sequentially, produces harmful gases to reduce the food chain such that most fraction of organic matter is not further used or decomposed by respiration but could be sequestered in sediments and may buried to produce fossil fuel in the long run. Thus this phenomenon could be ascribed as the one of the most important methods for long-term storage of carbon-dioxide or other forms of carbon to either mitigate or differ global warming for avoiding the adverse effects of climate change. |
