Question

there are more than 300 species of sharks. approximately 70 species, such as the great white shark, are nearing extinction because of hunting.

question 8
which of the following human actions will have the most positive effect on the survival of these species of sharks?

• identifying and protecting areas of the ocean with a diversity of shark species
• investigating industrial fishing where sharks are a by-product that is caught and discarded
• completing research showing slow reproduction rates in sharks compared to other vertebrates
• creating shark-management programs to prevent sharks from approaching humans swimming in areas near populated coastlines

Analyze the problem context

The text states that approximately 70 species of sharks are nearing extinction due to hunting. We need to identify which human action will have the most positive effect on the survival of these threatened shark species.

Evaluate the first option

The first option suggests "Identifying and protecting areas of the ocean with a diversity of shark species." This directly addresses Species Conservation Status by establishing marine protected areas (MPAs) where hunting is restricted, allowing multiple threatened species to recover in their natural habitats.

Evaluate the second option

The second option suggests "Investigating industrial fishing where sharks are a by-product that is caught and discarded." While investigating is a useful scientific step, investigation alone does not actively protect the sharks or stop them from being killed unless followed by direct regulatory action.

Evaluate the third option

The third option suggests "Completing research showing slow reproduction rates in sharks compared to other vertebrates." Similar to the second option, conducting research provides valuable data but does not directly implement a protective measure to improve their immediate survival rates.

Evaluate the fourth option

The fourth option suggests "Creating shark-management programs to prevent sharks from approaching humans swimming in areas near populated coastlines." This action focuses on human safety and keeping sharks away from beaches, which does not protect sharks from hunting or help conserve threatened species in the open ocean.

Select the best action

Comparing all options, establishing protected areas (Option 1) is a direct, active conservation strategy that provides immediate habitat protection, making it the most effective action for the survival of these species.
