Coastal Erosion and Solutions

The video introduces the concept of coastal erosion and its impact on coastal areas, using Portsea as a case study. It discusses various solutions to combat erosion, such as sea walls and vegetation, and encourages viewers to design their own solutions. The presenter shares their solution, which includes offshore rocks and a concrete swimming pool, and invites viewers to compare and improve upon it.
