The Great Pacific Garbage Patch is an extensive collection of garbage that occupies large areas in the Pacific Ocean. It is made up of mostly small pieces of broken-down plastics that increase the turbidity of the top few meters of the water.

Identify which of the following describes the marine pollution shown in the Figure.

I.
It results from waste being released into both fresh and marine water bodies.
II.
It is created by the movement of ocean currents.
III.
It is classified as “floating debris” as a pollution type.

The Great Pacific Garbage Patch is an extensive collection of garbage that occupies large areas in the Pacific Ocean. It is made up of mostly small pieces of broken-down plastics that increase the turbidity of the top few meters of the water.

A common model addressing strategies to reduce pollution and its effects is called the “Replace, Regulate, Restore” model.

Deduce which of the following strategies would be considered a “restore” (cleaning up and restoring) strategy for dealing with this type of water pollution.

They indirectly measure pollution by counting individuals of species that are indicators of the presence of certain types of pollution.
II.
They can be calculated using mathematical formulas.
III.
They are classification tools similar to a dichotomous key.
IV.
They measure the amounts of key water pollutants.
