Overview of Ocean Pollution
Ocean pollution refers to the introduction of harmful substances into marine environments. These pollutants come in various forms, with plastics being a considerable concern. Plastics, because of their durability and versatility, have proliferated in daily life. However, this same durability makes them resistant to degradation once discarded. Consequently, plastics persist in oceans for hundreds of years, leading to severe ecological consequences.
As plastics break down into smaller pieces, known as microplastics, they become less visible yet more insidious. These particles infiltrate various marine organisms, from plankton to larger species, including fish and mammals. As a result, plastic pollution is now recognized as a critical threat to biodiversity and ecosystem integrity.
