When it comes to the marine heritage of the Eastern coast of India, the vast stretch of Bay of Bengal is the shining embellishment that the country possesses. But in the course of years of technological development and advancement in industrial production, mankind has caused immeasurable damage to the kind and selfless environment. Coming to the coast of Bay of Bengal, in the past few years, the contamination of seashores by chemical pollutants has rendered 60,000 sq.km of coastal area ‘dead’ and hence the title- dead zones.
According to global scientists, there are more than 450 dead zones in the world. The dead zones are low-oxygen water bodies within marine ecosystem where life cannot exist. Excessive nutrient pollution and other factors deplete the oxygen content in the water. This leads to mass mortality of fish and marine animals.
The lack of strict enaction of rules by the government in controlling the amount of industrial waste,fertiliser runoff and sewage that enters the sea has led to this catastrophic consequence which us claiming the lives of thousands of marine organisms. If this continues, the marine biodiversity will have to face a painful extinction in the future. This eventually has a grave impact on the balance of the ecosystem which is essential for life to survive on Earth.
A handful of the 166 dead zones have since bounced back through improved management of sewage and agricultural runoff, but as fertilizer use and factory farming increase, we are creating dead zones faster than nature can recover. This shows that dead-zones are not irreversible. With sincere and dedicated steps, we-the children of Mother Nature-can help in reversing the condition of dead-zones and insure the future of marine life in turn guaranteeing the wonderful future of our planet. We must voice our opinions and ask for the formation and implementation of rules that protect the aquatic environment. We, together, with concerted efforts can bring back the lost glory of our divine oceans.
