Human activity can destroy coral reefs. Because so many organisms depend on the coral, this can have a negative effect on the ecosystem in shallow ocean waters. Which of the following solutions could most likely offer the best way for humans to repair the damage and improve the health of this ecosystem?

Pick One:

Design nets to catch the kinds of fish that use coral reefs as a food source
Introduce non-native species into the shallow ocean that don’t depend on coral
Use submarines to gather data on the amount of coral reefs lost each year
Submerge large structures on which new coral reefs can form and grow
