Bottom trawling is a method of deep sea fishing in which a large net is used to ravel across the sea floor bed. This causes the destruction of sea floor bed along with habitat destruction residing in close proximity to sea bed. It adversely affects the sea plant, and coral reefs which get uprooted and destroyed.
Hence, the statement "Bottom trawling is a destructive fishing practice that destroys ocean habitats" is true.
Infectious diseases are caused by the passing of one person to another. Corona is an example. Noninfectious diseases, they are just spread by pathogens. Good luck!
