Based on the data table below, what is the maximum level of net fishing can the lake model SUSTAIN?
15%
35%
55%
75%
Which of the following is a disadvantage of overfishing?
Over 3 billion people worldwide depend on seafood as a protein source, so overfishing could cause these people to starve
The largest fish tend to be female, so overfishing will cause a decline in future fish stocks because there will be no females around to reproduce
Overfishing leads to bycatch, catching unintended fish in the nets
Dragging nets along the bottom of the ocean results in habitat destruction
All of the above
