Impact of CO2 on Marine Life

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 like clams and corals. This disruption threatens the ocean food chain and could lead to severe ecological consequences. The video emphasizes 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?

• No change in global temperatures

• Stabilized 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 emitter

• Carbon sink

• Carbon reservoir

Which marine creatures are affected by the weakening of shells due to increased CO2?

• Sharks and whales

• Clams, oysters, and coral

• Dolphins and turtles

• Seaweed and algae

What happens when CO2 reacts with seawater?

• It releases oxygen ions

• It releases sulfur ions

• It releases hydrogen ions

• It releases nitrogen ions

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

• 40% more acidic

• 30% more acidic

• 20% more acidic

• 10% more acidic

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

• Ecosystems will become less diverse

• Ecosystems will struggle to adapt

• Ecosystems will remain unchanged

• Ecosystems will thrive

What is the potential impact on coral reefs if CO2 emissions are not reduced?

• Coral reefs will expand

• Coral reefs will remain stable

• Coral reefs will become extinct

• Coral reefs will become more colorful

What is the primary source of the carbon dioxide problem discussed in the video?

• Agricultural practices

• Natural volcanic activity

• Burning fossil fuels

• Deforestation

What is the potential time frame for oceans becoming more acidic than they have been in millions of years?

• In a few years

• In a few decades

• In a few centuries

• In a few millennia

What is the proposed solution to the problem of increased CO2 emissions?

• Increasing deforestation

• Ignoring the problem

• Reducing fossil fuel use
