Lesson 1 and 2 - Water Moves in Patterns in Earth's Oceans - The Great Pacific Garbage Patch

As we have evolved, our needs have demanded the production of materials that are durable and weather-resistant - plastic! But what happens to all that plastic when we throw it away?

Respond in the chat.....

Explain which aspects of the video are true, which are exaggerated, and which merely are added for entertainment value.

Multiple Choice

What happens to the plastic over time?
