Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year. People who live in places with high levels of air pollutants have a 20% higher risk of death from lung cancer than people who live in less-polluted areas.
Considering this, why pollution in the ocean is bad?
Most ocean pollution begins on land. When large tracts of land are plowed, the exposed soil can erode during rainstorms. Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land.
How does pollution in the ocean affect the organisms?
Marine pollution occurs when harmful, or potentially harmful, effects result from the entry into the ocean of chemicals, particles, industrial, agricultural, and residential waste, noise, or the spread of invasive organisms. Air pollution is also a contributing factor by carrying off pesticides or dirt into the ocean.
How many dolphins are killed each year because of pollution?
Fact 3: Over one million seabirds are killed by ocean pollution each year. Three hundred thousand dolphins and porpoises die each year as a result of becoming entangled in discarded fishing nets, among other items. One hundred thousand sea mammals are killed in the ocean by pollution each year.
