Ocean Acidification and Its Effects

Ocean acidification, known as the 'other carbon problem,' is caused by carbon dioxide emissions from burning fossil fuels. This process increases ocean acidity, threatening marine life and ecosystems, particularly coral reefs. The only way to halt acidification is to reduce carbon emissions. Additionally, maintaining healthy marine systems through conservation efforts can help mitigate the effects. The video emphasizes the urgency of addressing both local and global environmental challenges to preserve ocean health.

What is referred to as the 'other carbon problem' alongside global warming?

• Air pollution

• Ocean acidification

• Deforestation

• Soil erosion

How does carbon dioxide affect ocean water chemically?

• It solidifies

• It evaporates

• It becomes an acid

• It turns into a base

Since the Industrial Revolution, by what percentage has ocean acidity increased?

• 10%

• 40%

• 20%

• 30%

What happens to marine species that rely on calcium carbonate when ocean acidity rises?

• Their shells dissolve

• They grow faster

• They migrate to deeper waters

• They become more colorful

Why are coral reefs particularly sensitive to ocean acidification?

• They are located in shallow waters

• They cannot form skeletons quickly

• They are isolated ecosystems

• They are exposed to sunlight

What is the estimated number of species living in coral reef structures?

• 2 million

• 5 million

• 1 million

• 500,000

What is a major consequence of higher ocean acidity on the food chain?

• Increase in fish population

• Extinction of basic food source creatures

• Improved water clarity

• More algae growth

What is one of the key strategies to stop ocean acidification?

• Build more dams

• Emit less carbon dioxide

• Increase fishing activities

• Use more fertilizers

How can the ocean better defend itself against rising acidity?

• By increasing its temperature

• By having healthy systems

• By expanding its size

• By reducing its salinity

What is a local solution to improve marine ecosystem health?

• Establishing more oil rigs

• Restoring depleted fish populations

• Introducing invasive species

• Increasing coastal development
