What are two factors that have contributed to increased fishing in deep ocean waters in recent years?
a. fish overbreeding and air pollution
b. human population growth and decreased fishing opportunities inshore
c. increased biodiversity in deep waters and increased growth of coral reefs
d. marine pollution and increased fish populations

The two factors that have contributed to increased fishing in deep ocean waters in recent years are the human population growth and decreased fishing opportunities inshore. Increase population growth increases the demand for food which also leads to increase in fish demand. Because the fish demand is high, inshore fishing opportunities decrease that is why deep ocean waters is the new venue for fishing.
