Answer:
1.Eutrophication, dystrophication or hypertrophication, is the process by which a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body after the bacterial degradation of the algae.
2.Eutrophication most commonly arises from the oversupply of nutrients, most commonly as nitrogen or phosphorus, which leads to overgrowth of plants and algae in aquatic ecosystems. After such organisms die, bacterial degradation of their biomass results in oxygen consumption, thereby creating the state of hypoxia.
3.Globally, 100,000 marine mammals die every year as a result of plastic pollution. This includes whales, dolphins, porpoises, seals and sea lions. There are two principle ways that encountering marine debris can be fatal for these creatures: ingestion (eating) or entanglement in plastic-based fishing gear.
4.We're drowning marine ecosystems in trash, noise, oil, and carbon emissions. ... And from dangerous carbon emissions to choking plastic to leaking oil to constant noise, the types of ocean pollution humans generate are vast. As a result, collectively, our impact on the seas is degrading their health at an alarming rate.
