Ocean Acidification Impact and Solutions

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 emphasizes the need to reduce fossil fuel use and advocates for renewable energy and public awareness to combat this issue.

What is the primary cause of ocean acidification?

• Increased sunlight

• Absorption of carbon dioxide

• Overfishing

• Oil spills

How does increased carbon dioxide affect ocean organisms?

• It enhances their growth

• It improves their metabolism

• It affects their physiological functions

• It makes them immune to diseases

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

• Silica

• Magnesium

• Calcium carbonate

• Iron

Why are oysters considered ecologically important?

• They produce oxygen

• They filter water and provide habitat

• They are a primary food source for humans

• They control ocean currents

What is the impact of ocean acidification on microscopic organisms in the Southern Ocean?
