4. Invasive / Non-native Species

5. Habitat Destruction

6. Heavy Metal Pollution

7. Synthetic Chemical Pollutants
Polychlorinated biphenyls (PCBs) -
Stored in the fatty tissue or organs of animals, where they can have toxic effects. For example, they can disrupt the endocrine system, cause cancer or genetic defects, and weaken the immune system

16. Threats to the Marine Environment Questions Cont. 1
Threats to the Marine Environment Questions Cont. 1. Of the threats to the ocean we just discussed in class, which do you think puts the ocean’s health most critically in danger? Why? 2. Select three of the threats and explain at least one consequence for each that could occur if nothing is done to stop the problem. 3. Whaling involves the poaching of only a few species of animal. How is this still a problem for the ocean as a whole? 4. Describe at least three things you can do in your daily life to help minimize threats to ocean.
