Singapore is moving its shoreline. Fujairah is expanding its terminals. Palm Jumeirah reshaped the Gulf. The Netherlands keeps reinforcing land that sits below sea level. The coast is no longer just where land meets water. It is where trade grows, where artificial islands appear, where shipping concentrates, where cities discharge, and where sea level keeps rising. This episode is about what happens when we build outward, enclose water, multiply infrastructure and then act surprised when currents shift, fish disappear and erosion accelerates. If you live near the Gulf, in Southeast Asia, in Europe or anywhere within 100 kilometres of the sea, this is not abstract. This is your coastline.
