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

If Carbon emissions into the atmosphere do not decrease, how will this impact the ocean?

• The ocean will become more acidic

• The ocean will become colder

• Carbon Dioxide will be absorbed into the ocean, causing the ocean to have more gas bubbles

• Carbon emissions in the atmosphere will not impact the hydrosphere

Based on the graph above, what do you project will happen to sea life species populations after 200 years have passed?

• The Long-Spined Sea Urchin and Hawksbill Sea Turtles populations will decline, but will still survive

• All Sea Life will go extinct

• The Staghorn Coral will evolve and adapt to the changing acidity levels of the Ocean and will thrive in the new environment

• Some Sea Life populations will increase, and Sea Life populations with shells will decrease
