- Marine Pollution
Oceans are the largest water bodies on the planet Earth.
Pollution entering our oceans from both man-made and natural activities is affecting marine ecosystems throughout the world. Animals often eat these pollutants which, means humans will as well. Runoff from the land comes from both urban and agricultural areas. Chemicals that end up on roads and highways flow over and under the ground with rainwater, as do pesticides; fertilizers; and carbon-, nitrogen-, and phosphorous-rich particulates, eventually reaching the ocean. Inland mining can cause an influx of mineral and soil deposits.
Causes & effects of ocean pollution
The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world. The waters of the River Ganges flow clear and clean through the Indian city of Rishikesh at the gateway to the Himalayas.
Water pollution is the contamination of water bodies , usually as a result of human activities. Water bodies include for example lakes , rivers , oceans , aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation.
Marine pollution is defined as the introduction of substances to the marine environment directly or indirectly by man resulting in adverse effects such as hazardous to human health, obstruction of marine activities and lowering the quality of sea water. Municipal waste and sewage from residences and hotels in coastal towns are directly discharged into sea. Pesticides and fertilizers from agriculture which are washed off by rain enter water courses and finally to sea. India is estimated to use 55, tons of pesticides annually and about 25 percent of it is carried to-ocean. Ship accidents and accidental spillage at sea can therefore be very damaging to the marine environment. Dry docking: All ships periodic dry docking servicing; cleaning the hulls etc.
Ocean Pollution: Causes, Effects and Prevention
Oceans, which account for 70 percent of the surface of our planet, play a pivotal role in the health of our planet and those who inhabit it. Unfortunately, our oceans are polluted. According to the National Oceanic and Atmospheric Administration , billions of pounds of trash and other pollutants enter our oceans every year. The monumental impacts of this are far-reaching. There are many causes of ocean pollution. Of all the facts, there is one constant: most pollution in our oceans begins on land and is caused by humans. Here are some of the major causes of marine pollution:.
