This short video gives some important data (numerical, or number, information) about the garbage patch that we learned about in class.
QUESTIONS: You may need to stop the video and take a few notes.
What percent of the garbage patch’s rubbish (trash) comes from land sources? What percent comes from water sources?
Zooplankton are floating animals that range in size from microscopic to jellyfish-size. They usually float or drift near water surfaces since that his where they find their food. Zooplankton are biotic – a life form. Plastic is abiotic – not a life form. It is also synthetic – not a natural substance. Consider how the amount of plastic in the ocean has increased in weight compared to zooplankton. This is where the anthrosphere crashes into the hydrosphere and has major effects on the biosphere.
- How many pounds of plastic were there in the ocean in the year 1900 (112 years ago) for every one pound of zooplankton?
- How many pounds of plastic were in the ocean in 2000 (12 years ago) for every pound of zooplankton?
- How many pounds of plastic for every pound of zooplankton now (or 2 years ago, when the video was made)?
How many known garbage patches are there in the world? Where are they?
