Answer:
C. Rapid population growth
Step-by-step explanation:
With rapid population growth, more houses are being made and new resources. The ecosystem is being damaged by making highways and new houses and lands for people to live on. Controlled water use would help the ecosystem because humans aren't drawing too much water. Decreased resources use would save fossil fuels and nonrenewable resources. Regulation of fishing practices would prevent the ocean from being overfished from. That's why C is the correct answer.
