Answer to Question 1

The very same properties that make plastics so advantageous make them unusually persistent and damaging when released into the marine environment: They are lightweight, so they float and concentrate at the surface; They are strong, so they entangle marine organisms; They are durable, so they don't biodegrade easily, causing them to last almost indefinitely; They are inexpensive, so they are mass-produced and used in almost everything.

Answer to Question 2

B
