Problem
Read the following paragraph. One cause of overfishing has been a cavalier attitude toward the earth's oceans. Fishers and fishing fleets saw oceans full of fish and concluded that the oceans were inexhaustible. They treated the oceans as if their actions would have no future consequences. Take as many fish as you want; throw out or kill what you do not want; do whatever harm you want: these attitudes have all too often ruled the seas. What does the word cavalier mean as it is used here?
