Arctic ocean acidification threatens fish lifecycle and livelihood of arctic environment.

The video discusses how carbon dioxide in the atmosphere is absorbed by the world's oceans, particularly the colder Arctic waters. This absorption leads to increased acidification, which negatively affects the ability of some sea creatures to grow and calcify shells, and impacts fish larvae survival. Currently, Arctic Ocean acidity is 30% higher than at the start of the industrial revolution.

What is the primary focus of the world's oceans in absorbing carbon dioxide?

• Colder Arctic waters

• Tropical waters

• Mountain ranges

• Desert regions

How does increased acidification affect marine life in the Arctic Ocean?

• It has no impact on marine life

• It hinders the ability of sea creatures to grow and calcify shells

• It improves the survival rate of fish larvae

• It enhances the growth of coral reefs

What is one of the challenges faced by fish larvae due to ocean acidification?

• Increased food supply

• Improved swimming abilities

• Enhanced growth rates

• Difficulty in surviving

By what percentage has Arctic Ocean acidity increased since the industrial revolution?

• 40%

• 10%

• 20%

• 30%

What historical event marks the baseline for measuring the increase in Arctic Ocean acidity?

• The Renaissance

• The Industrial Revolution

• World War I

• The Space Age
