The coastal and marine nitrogen cycle occupies a complex, central role within the biogeochemical cycles. Human interventions in the earth system have risen to unprecedented levels, strongly influencing the global nitrogen cycle. The nitrogen cycle in the open ocean compared to coastal ecosystems appears to have remained unharmed, although recent observations have shown increasing anthropogenic influence.

The coastal marine environment provides enormous value in fishery and other products and in ecosystem services including coastal protection, water purification, and appropriate locations for ports, harbors, urban centers, tourist destinations, and numerous recreational pursuits.

A public interest litigation was filed in the High Court recently against the state government, seeking directions to the Andhra Pradesh Pollution Control Board (APPCB) to rectify its faulty norms in according permission for setting up industries without studying the impact on bio-diversity and greenery. The PIL disputed the norms of the APPCB for setting up an industrial unit.

Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to ~3% of the annual new marine biological production, ~0.3 petagram of carbon per year. This input could account for the production of up to ~1.6 teragrams of nitrous oxide (N2O) per year.

The appearance of ugly, polluting tar balls on the pristine beaches of Pernem recently point to the fact that ships continue to discharge oil into Goa's coastal waters in blatant violation of environmental norms governing the shipping industry.

The Coastal Corridor and SEZ Act would deprive the common man of his basic right to life, said the convenor of the Coastal Corridor Nirmana Vyatireka Porata Committee, Mr K.S. Chalam, and the state secretary of the Human Rights Forum, Mr V.S. Krishna. Addressing a press conference here on Monday, they said the 8-day Jagruti Jatha organised by both the organisations seeking scrapping of GO No. 34 and the SEZ Act, 2005, ended on Sunday.
