India falls in the confluence of the three major biogeographic realms India- Myanmar, Eurasian Afro-tropical and is one of the 12 mega biodiversity countries of the world. It also represents two biodiversity hotspots of the world namely western Ghats and North Eastern Himalayas.

Causative factors blooms: upwelling, formation of mud banks, nutrient discharges from estuaries and run off from the land during south west and northeast monsoon cause some algae blooms in coastal waters. The changing patterns of nutrient ratio of the costal and the open ocean water due to anthropogenic activities increased aquaculture operations leading to enrichment of coastal waters, dispersal of toxic species through currents, storms, ship ballast waters and shell fish seeding activities were some of the factors triggering the blooms.

Harmful algal blooms (HAB), lethal for human beings and marine ecosystems alike, are steadily increasing in intensity in the Indian waters. Researchers have found out of the toxic blooms had increased by around 15 percent over the last 12 years in Indian seas.

In photosynthesis the carbon dioxide is absorbs by the plants and the oxygen is released. It does not add carbon dioxide to the carbon cycle. In respiration oxygen is converted to tissues and cells and the oxidation products, carbon dioxide and water are given off. The most abundant gas typically released into the atmosphere from volcanic systems is water vapour, followed by carbon dioxide and sulfur dioxide. A composting process convert organic matters into stable compost that is odor and pathogen free, and a poor breeding substrate for flies and other insects and releases carbon dioxide.
