CLEAN : Dutch inventor harnessing waves to clean up the seas

The video discusses the development and testing of an ocean cleanup system designed to withstand extreme conditions, particularly in the North Sea. The system uses long floating barriers to concentrate and collect plastic waste, leveraging ocean currents. The speaker shares a personal story of realizing the plastic pollution problem while diving in Greece. The video also explains how ocean currents transport plastic across oceans, leading to the formation of garbage patches in subtropical areas.

Why is the North Sea considered a good test site for ocean structures?

• It has calm waters.

• It has strong currents that simulate extreme conditions.

• It is close to the Pacific Ocean.

• It is free from plastic pollution.

What is the primary function of the long floating barriers developed by the Ocean Cleanup project?

• To create artificial coastlines.

• To prevent oil spills.

• To capture fish.

• To concentrate plastic waste using ocean currents.

How does the V-shape of the barriers help in the cleanup process?

• It reduces the size of the barriers needed.

• It increases the speed of ocean currents.

• It prevents marine life from entering.

• It directs plastic waste towards the center for easy collection.

What realization did the narrator have while diving in Greece?

• The ocean is self-cleaning.

• Plastic waste moves around due to ocean currents.

• Plastic waste stays in one spot.

• There were more fish than plastic bags.

What are ocean gyres and how do they affect plastic pollution?

• They are man-made structures to trap plastic.

• They are regions with high fish populations.

• They are circular currents that concentrate plastic waste.

• They are areas with no ocean currents.
