Cargo ship and Marine Polution in Madura Strait of Surabaya port

The ship that we see in the following picture was in Port of Surabaya. The port is located in Madura strait. One of the busiest waters in Indonesia. Every day hundreds of cargo ships, passenger ships, tankers and bulk carrier arrive and leave port of Surabaya. As the second largest city in Indonesia with millions of city dwellers, Surabaya exports and imports various kinds of goods that are transported by the ships. Day by day, the number of ships that sail through the Madura strait is increasing. When I was on a boat in the middle of the strait several years ago, I saw that the color of the sea water was not clear blue anymore. The Madura strait has been heavily polluted by wastes from these ships and from the industrial and domestic wastes that flow to the strait both from Madura island and Surabaya. 

No wonder the quality of marine life in the strait is low. Efforts to clean the strait should be done to improve the water quality in the strait so that marine life can live in the area again. Also read:
