How can humans stop coastal erosion?

Humans can implement various strategies to stop coastal erosion, such as building seawalls, installing breakwaters, planting mangroves or other vegetation, and replenishing beaches with sand. Proper land use planning and sustainable coastal development practices can also help minimize erosion. Additionally, reducing greenhouse gas emissions to mitigate climate change and its impacts on sea level rise can play a significant role in protecting coastal areas from erosion.
