Using the image provided, which answer choice correctly summarizes how the pollution from the factory and the commercial fishing industry are connected?

• The factories provide nutrients for the fish, increasing their populations, which in turn helps the fishing industry by increasing their profits. 

• The factories produce pollution, which ends up in the water, reducing the number of animals in the oceans. The fishing industry then cannot catch enough fish to meet the demand. 

• The fishing boats produce pollution, which impacts the factory’s ability to produce its product.

• The fishing boats catch the majority of fish in the oceans, which prevents the factories from having the required materials to function.
