it always come from people.
Marine pollution occurs when harmful effects, or potentially harmful effects, can result from the entry into the ocean of chemicals, particles, industrial, agricultural and residential waste, noise, or the spread of invasive organisms. Most sources of marine pollution are land based. The pollution often comes fromnonpoint sources such as agricultural runoff and wind blown debris.
It comes from Old English (North of England) for Woodcutter or Woodsman. It has no relation to any Arabic word, which is a common misconception.
Pollution that comes from only one source is called point source pollution. This type of pollution is often easier to identify and regulate compared to non-point source pollution, which comes from multiple sources.
point soarce pollution
Land-based sources, such as plastic waste, oil spills, and agricultural runoff, are the primary contributors to ocean pollution. Other sources include shipping and fishing activities, as well as industrial and sewage discharges. These pollutants can harm marine life, disrupt ecosystems, and affect human health.
the difference is that a point source pollution comes from a specific site & the non-point source pollution comes from many sources rather than a single specific site. or point source pollution is pollution that comes from a known and specific location. Nonpoint source pollution is pollution that does not have a specific point of orign....................:-)Hisme John
A marine environmentalist is a person who specialise in the pollution of the sea and the well being of the investigate the causes of that particular pollution,comes up with solutions of combating the problem,find the most places that are vulnerable in being polluted the most and ensures that the future generations are going to be left with a good and secure environment.
The kind of pollution comes from track able sources is usually trash pollution in the water. Air pollution and fossil fuel pollution are also track able sources.
Point source pollution comes from a single identifiable source, such as a factory or a sewage treatment plant. This type of pollution is easier to monitor and regulate compared to non-point source pollution, which comes from multiple dispersed sources.
Domestic pollution is caused by landfill waste seeping into the groundwater flow. Agricultural pollution comes from farms. It occurs when the farmers spray their land with pesticides and fertilisers which then run off the land when its raining , into nearby water sources . This pollutes the water and the marine life living in it. :)
pollution is the steam that comes out of a train
