Exploring the Effects of Ocean Acidification on Earth

The video explores the challenges facing global water resources, focusing on ocean acidification. It highlights the impact on marine life, particularly oysters in Puget Sound, and the efforts to restore oyster populations. The video also discusses the broader ecosystem effects and ongoing research to understand these changes. Viewers are encouraged to learn more and take action through Earth Echo International.

What is one of the main threats to global water resources mentioned in the introduction?

• Overfishing

• Ocean acidification

• Air pollution

• Deforestation

Why did the oyster population in Puget Sound become a focal point for ocean acidification studies?

• They are a major food source for humans.

• They experienced a significant die-off due to acidification.

• They are immune to acidification effects.

• They are the largest shellfish species.

What makes the Olympia Oyster less vulnerable to ocean acidification?

• They feed on a special type of plankton.

• They live in deeper waters.

• They brood their larvae internally.

• They have a thicker shell.

How do oysters contribute to marine ecosystems beyond being a food source?

• They clean the water by filtering it.

• They prevent coastal erosion.

• They provide habitat for other marine life.

• They produce oxygen for fish.

What is the primary focus of the research at NOAA's Northwest Fisheries Science Center?

• Monitoring water pollution levels.

• Developing new fishing techniques.

• Analyzing the effects of ocean acidification on marine food chains.

• Studying the migration patterns of whales.

Which marine species is directly linked to the food chain affected by ocean acidification in Puget Sound?

• Dolphins

• Sea turtles

• Orca whales

• Sharks

What is the role of crab larvae in the marine ecosystem as discussed in the research section?

• They are a primary food source for salmon.

• They clean the ocean floor.

• They are used in medical research.

• They help in coral reef formation.
