Impact of Ocean Acidification

The video discusses how human activities, particularly the burning of fossil fuels, are increasing carbon dioxide levels in the atmosphere, leading to global warming and climate change. The oceans, acting as a carbon sink, have absorbed much of this CO2, but this has led to ocean acidification, which threatens marine life such as clams, oysters, and coral. The video highlights the cascading effects on the marine food chain and emphasizes the urgency of addressing CO2 emissions to prevent further damage to ocean ecosystems.

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

• Decreased global temperatures

• Increased global temperatures

• Stabilized global temperatures

• No change in global temperatures

Why are oceans referred to as the planet's biggest carbon sink?

• They increase carbon dioxide levels

• They release carbon dioxide into the atmosphere

• They absorb a large amount of carbon dioxide

• They have no effect on carbon dioxide levels

What happens to the ocean's ability to absorb CO2 as it warms?

• It remains the same

• It increases

• It decreases

• It fluctuates unpredictably

How does increased CO2 in seawater affect marine creatures like clams and oysters?

• It has no effect on their shells

• It makes their shells grow faster

• It weakens their shells

• It strengthens their shells

What do hydrogen ions released by CO2 in seawater compete with?

• Nitrogen ions

• Oxygen ions

• Sodium ions

• Carbonate ions

What is a potential consequence of weaker shells in marine life?

• Increased marine biodiversity

• No impact on marine ecosystems

• Stronger marine food chains

• Disruption of marine food chains

By how much has ocean acidity increased since the industrial revolution?

• 10%

• 20%

• 30%

• 40%

What is the potential impact of ocean acidification on coral reefs?

• They may dissolve and disappear

• They will become more colorful

• They will thrive and expand

• They will remain unchanged

What is the main cause of the problems discussed in the video?

• Natural ocean currents

• Volcanic eruptions

• Burning fossil fuels

• Deforestation

What is the suggested solution to address the root cause of ocean acidification?

• Increase fossil fuel usage

• Reduce carbon dioxide emissions

• Ignore the problem

• Increase ocean temperatures
