Question

What are the sources of marine pollution and What is the impact of marine life?

Answer 1

Hint: Marine pollution occurs when harmful effects are caused by the entry into the sea of ​​chemicals, particles, industries, agriculture and habitats, noise, or biodiversity. Eight percent of the world's pollution comes from land. Air pollution also contributes to the spread of pesticides or pollution into the sea.

Complete answer:
Pollution of land and air has proven to be detrimental to marine life and the environment in which they live. Oil spills are dangerous to marine life in many ways. Oil spilled from the sea can get into patients and seabirds, making it difficult for them to walk or swim properly or to feed their babies. Long-term effects on marine life can include cancer, reproductive failure, behavioral changes, and even deathMost of the debris in the sea does not rot and stays in the sea for years. It uses oxygen as it degrades. As a result, oxygen levels drop. As oxygen levels drop, the chances of survival of marine animals such as whales, tortoises, sharks, dolphins, penguins also decline.Industrial and agricultural waste includes a variety of toxic chemicals that are considered hazardous to marine life. Chemicals from pesticides can accumulate in the fatty tissue of animals, leading to the failure of their reproductive systemIndustrial and agricultural chemicals are washed into the river and then dumped into the sea. These chemicals do not melt and sink to the bottom of the ocean. Small animals swallow these chemicals and are later eaten by larger animals, affecting the rest of the food chain.

Note: Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen, silicon, sulfur, pesticides or dust particles into the ocean. Land and air pollution have proven to be harmful to marine life and its habitats.
