Impact of Ocean Acidification

The video discusses how human activities are increasing carbon dioxide levels, leading to global warming and climate change. Oceans, as major carbon sinks, absorb much of this CO2, but this causes ocean acidification, affecting marine life and food chains. The video highlights the weakening of marine organisms' shells due to increased acidity and the broader implications for ecosystems. It stresses the urgency of addressing CO2 emissions from fossil fuels to prevent further damage.

What is one of the main consequences of increased carbon dioxide in the atmosphere?

• Stabilized global temperatures

• No change in global temperatures

• Increased global temperatures

• Decreased global temperatures

What is the term used for the ocean's ability to absorb carbon dioxide?

• Carbon source

• Carbon sink

• Carbon reservoir

• Carbon emitter

Why are the shells of marine creatures like clams and oysters becoming weaker?

• Due to increased salinity

• Due to lack of sunlight

• Due to overfishing

• Due to competition for carbonate ions

What happens when CO2 reacts with seawater?

• It releases oxygen ions

• It releases hydrogen ions

• It releases nitrogen ions

• It releases sulfur ions

How much more acidic has the ocean become since the start of industrial CO2 emissions?

• 30% more acidic

• 20% more acidic

• 10% more acidic

• 40% more acidic

What could happen to marine ecosystems if ocean acidity continues to increase?

• Ecosystems will become more diverse

• Ecosystems will thrive

• Ecosystems will struggle to adapt

• Ecosystems will remain unchanged

What is the potential impact on coral reefs if ocean acidity is not addressed?

• Coral reefs will dissolve

• Coral reefs will remain stable

• Coral reefs will expand

• Coral reefs will become more colorful

What percentage of ocean species live in coral reef ecosystems?

• 1 in 3

• 1 in 5

• 1 in 4

• 1 in 2

What is the primary source of the carbon dioxide causing ocean acidification?

• Agricultural activities

• Natural volcanic activity

• Burning fossil fuels

• Deforestation

What is the proposed solution to address the problem of ocean acidification?

• Increase ocean salinity

• Ignore the problem

• Reduce carbon dioxide emissions

• Increase fossil fuel usage
