Which of the following is an example of climate change adaptation in coastal areas?

• A. Building sea walls.
• B. Increasing fossil fuel usage.
• C. Clearing mangroves.
• D. Ignoring sea-level rise.

Answer: (A)

Climate change adaptation means taking practical steps to reduce the harm from rising seas, stronger storms, and flooding. In coastal areas, building sea walls directly reduces flood risk by acting as a physical barrier that slows or blocks ocean water from overtopping into land and protecting infrastructure from erosion. This proactive measure helps communities cope with higher sea levels and more extreme events. The other options don’t fit adaptation: increasing fossil fuel use worsens climate change, clearing mangroves removes natural protection against waves and storm surge, and ignoring sea-level rise means no action to prepare for changing conditions.
