Ocean Acidification Impact and Solutions

The video explains ocean acidification, a process where carbon dioxide from fossil fuels is absorbed by oceans, making them more acidic. This affects marine life, particularly organisms like oysters and corals. The video highlights research using historical coral data to understand past and predict future acidification. It emphasizes the human role in exacerbating this issue and the potential for mitigation. The Salish Sea is used as a case study to illustrate these impacts.

What is the primary cause of ocean acidification?

• Carbon dioxide absorption

• Oil spills

• Increased salinity

• Overfishing

How has ocean acidification changed over the last 150 years?

• It has decreased due to natural processes.

• It has remained constant.

• It has accelerated due to fossil fuel emissions.

• It has only recently started.

Why are corals considered good indicators of ocean acidification?

• They are immune to acidification.

• They are sensitive to changes in ocean chemistry.

• They are found only in tropical regions.

• They do not change over time.

What role do historical corals play in ocean acidification research?

• They are only found in the tropics.

• They are irrelevant to current research.

• They are used to increase ocean acidity.

• They provide a baseline of past ocean chemistry.

How can understanding the pace of ocean acidification help us?

• It shows that acidification is not a problem.

• It helps in planning conservation efforts.

• It proves that acidification is irreversible.

• It allows us to ignore future changes.

What natural process exacerbates acidification in the Salish Sea?

• Increased fish population

• Decreased sunlight

• Upwelling of naturally acidic water

• Increased rainfall

What is a significant impact of ocean acidification on marine life?

• Improved coral growth

• Difficulty for salmon to navigate

• Easier shell formation for oysters

• Increased fish population

How does ocean acidification affect human activities?

• It has no impact on human activities.

• It enhances recreational fishing.

• It threatens commercial fisheries.

• It improves water quality.

What is a potential solution to mitigate ocean acidification?

• Ignoring the problem

• Reducing carbon emissions

• Increasing ocean salinity

• Increasing carbon emissions

Why is the Salish Sea significant in studying ocean acidification?

• It is unaffected by acidification.

• It is isolated from human impact.

• It provides a window into future changes.

• It has no marine life.
