Ocean Acidification and Its Impacts

Ocean acidification is caused by the ocean absorbing CO2, leading to chemical changes that make the ocean more acidic. This affects marine life, especially organisms with calcium carbonate shells, and has economic impacts, particularly on industries like oyster farming. The video suggests reducing fossil fuel use and advocating for renewable energy as solutions.

What is the primary cause of ocean acidification?

• Pollution from plastic waste

• Overfishing

• Absorption of carbon dioxide by the ocean

• Increased ocean temperatures

How does increased CO2 concentration affect marine organisms?

• It enhances their growth

• It makes them more resistant to predators

• It has no effect

• It affects their metabolism and shell integrity

Which material do many ocean organisms use to build their skeletons?

• Silica

• Calcium carbonate

• Magnesium

• Iron

Why are oysters considered ecologically important?

• They produce oxygen

• They are a primary food source for humans

• They filter water and provide habitat for other organisms

• They are the largest marine organisms

What is the impact of ocean acidification on the food chain?

• It has no impact

• It strengthens the food chain

• It only affects top predators

• It disrupts the base of the food chain

What economic sector is directly affected by ocean acidification on the West Coast?

• Oyster farming

• Tourism

• Oil drilling

• Shipping

How has the government responded to the economic impact of ocean acidification?

• By banning all fishing activities

• By increasing fossil fuel usage

• By ignoring the issue

• By recognizing it as a significant problem

What is the most effective way to combat ocean acidification?

• Increase fishing quotas

• Stop burning fossil fuels

• Build more dams

• Reduce plastic usage

What role can individuals play in addressing ocean acidification?

• By traveling more

• By avoiding seafood

• By using their voices to raise awareness

• By staying silent

What energy sources should we turn to in order to help the oceans?

• Coal

• Fossil fuels

• Nuclear energy

• Clean and renewable energy sources
