The video discusses the critical issue of ocean acidification and its impact on marine ecosystems. Philippe Cousteau introduces Earth Echo's mission to find solutions. At NOAA's Pacific Marine Environmental Laboratory, Chris Sabine explains the research on ocean acidification and the need for affordable pH measurement tools. The video also highlights the Ocean Health XPRIZE, which incentivizes the development of new technologies to measure ocean pH, featuring insights from Paul Bunje and Will Barrow. The video emphasizes the importance of addressing multiple stressors affecting the oceans and encourages local actions to protect marine environments.

What is one of the main causes of ocean acidification?

• Decreased nitrogen levels

• Rising carbon dioxide levels

• Increased oxygen levels

• Increased salinity

How much carbon dioxide is absorbed by the oceans daily?

• 5 million tons

• 10 million tons

• 22 million tons

• 50 million tons

What is the primary goal of the Ocean Health XPRIZE?

• To reduce ocean temperatures

• To clean up ocean plastic

• To develop affordable pH measurement tools

• To increase fish populations

What is a significant challenge faced by teams in the XPRIZE competition?

• Increasing ocean currents

• Finding new marine species

• Reducing ocean salinity

• Developing low power consumption electronics

Why is ocean acidification considered a major threat?

• It reduces ocean currents

• It increases ocean salinity

• It affects marine life chemistry

• It increases ocean temperatures

What is one way to help oceans be more resilient?

• Increase fishing activities

• Reduce local pollution

• Build more coastal cities

• Increase ocean salinity

What is the role of phytoplankton in the ocean?

• They increase ocean temperatures

• They increase ocean salinity

• They produce oxygen

• They decrease ocean currents
