The Negative Effects of Marine Pollution

Oceanic perpetrators did not recognize the adverse effects on the oceans and the marine organisms they inhabited. Marine pollution is the cause of substances entering the sea and causing damage to marine life and water. Marine pollution continues from the beginning. Over time, many organizations and federal government have tried to defend the ocean from many injuries by strengthening the law, but this problem has been solved. Most people are currently aware of how bad the situation is, and there is little effort to solve this problem. The history of marine pollution can be traced back to the early life of mankind,

Marine pollution caused various changes in the physical, chemical and biological characteristics of the oceans and coastal areas, while adversely affecting biodiversity and ecological health. The three main sources of marine pollution are the direct discharge of sewage and solid waste from land and sea, the outflow of rivers, and atmospheric sedimentation. Overall, the most important of these threats is not maritime campaign, but a land operation, causing approximately 80% of the pollutants to enter the sea. Worldwide, the burning of agriculture, sewage, urban runoff, industrial wastewater and fossil fuels is the most common cause of nutrition pollution and their relative importance has considerable regional disparity (Selman et al ., 2008).

Human development has various effects on the marine environment. Demographic pressure can adversely affect marine life by habitat destruction, increased pollution, and promotion of global climate change. Salmon and trout are upstream fish and live in freshwater and sea water at every stage of life. The head of salmon and steel hatches with a stream of small fresh water and then moves downstream to the estuary and mature. Then they spent 2-6 years in the open sea where they mature, then hatched to lay eggs back to the same stream, and eventually died.
