Marine pollution definition causes effects and prevention
Answers
Answer:
Marine pollution refers to the contamination or presence of pollutants in oceans and seas. The word ‘marine’ comes from the Latin word for ‘sea’ and it is related to similar words, such as ‘mariner’. Ocean pollution is become ever more of a problem in the present day.
causes/Sources of Marine Pollution
1. Toxic chemicals in water.
2. Oil spillages.
3. Small particles.
4. Plastic, Litter, and human waste.
5. Sewage.
6. The shipping industry.
7. Dissolved greenhouse gases.
effects of Marine Pollution
1. Oxygen depletion.
2. Higher acidity.
3. Choking marine life.
4. Spoiling birds’ feathers.
5. Blocking out the sunlight.
6. Dangers to human health.
Control Measures/ Solutions for Marine Pollution
1. Be careful with our chemicals.
Climate change and marine pollution are both results of excess human interference in the natural world. If we choose eco-friendly household cleaners and take measures to reduce the fumes we release into the air (for instance, by choosing public transport over cars) we can reduce the impact of our lives on the oceans.
Further, careful site monitoring to prevent or stop any chemical or oil spills at all times will reduce the instances of oil spills.
2. Don’t flush or rinse away harmful particles.
If we do not flush plastics down the toilet, and if we do not pour oils and exfoliating beads down the faucet, we prevent these particles from reaching our oceans. Switch to exfoliants that use natural materials like seeds, sugar or sand instead – and recycle all plastics!
3. Campaign.
Influence the decisions of policymakers and factory bosses to make them more eco-friendly by lobbying, writing letters, spreading the word on social media and campaigning. Motivating the shipping companies to use safe and environmentally friendly vessels are among the key measures that can be taken here.
4. Volunteer at an oil spill site.
Volunteers are always needed at oil spill sites to save the lives of marine birds by washing the oil from their feathers and caring for them until they are ready to fly, swim and dive under water again. Intervention is always needed as soon as possible to ensure that these birds do not suffer any ill effects to their health.
5. Volunteer at a beach cleanup – or organize one yourself.
Rid your local beach of litter by getting together with the rest of the community to pick up the trash left behind by careless picnickers, boat crews and more. Joining together as a community to care for the natural world is a wonderful way to remind everyone how intimately we are connected to nature, and how much we depend on it. Working together with other people also helps to keep us motivated and reminds us that we are not alone in our quest to care for the environment.
6. Ensuring no debris is released into the ocean.
Recycling our plastics and other recyclable, and disposing of our waste responsibly is key here.
