Which of the following best explains why the environmental problems associated with trawling

A. Trawling always destroys sea floor ecologies

B. Trawling gathers fish indiscriminately

C. Trawling is too selective at gathering fish

D. All of the above.

The answer is A: Trawling always destroys sea floor ecologies

I believe this because trawling does exactly that. Trawling can harm not only fish but the habitats the fish reside in.

Answer: A. Trawling always destroys sea floor ecologies.

Explanation:

Trawling is a method of capturing the fishes. This involves pulling a large fish net called as trawl between the two ships or boats. These two vehicles on moving over the surface of water body captures the fishes and other aquatic organisms inside the net.

The trawl is liberated over the surface layers of the water, mid layers and bottom layers of the water body. The main disadvantage associated with the trawling process is that the trawl disturbs the plants and animals that stays over a bottom substratum. This results in the disturbance of the sea floor ecology.
