Take another look at the graph. In the late 1960s, yearly dolphin bycatch peaked around 700,000 before declining to nearly 0 by the early 1980s, after the Marine Mammal Protection Act of 1972. After the arrival of non-U.S. fishing fleets in the mid-1980s, there was another peak in dolphin bycatch, which reached 133,000 in 1986. When comparing these two peaks, what was the percent decrease between the peak of bycatch in the late 1960s (700,000) and the peak in 1986 (133,000)? 1% 19% 81% 95%
