Ship and coral reef

Ships are important vehicles that transport cargoes and people. Today, modern ships have bigger size and capacity. In the marine tourism world, cruise ship carries thousands of passengers. It is more like a floating city. The higher the capacity of a ship in carrying passengers or cargoes the better will be its efficiency. However, larger ships with higher number of passengers tend to produce higher amount of wastes. Wastes have three basic forms such as, gas, liquid and solid.
Although there are wastes processing machines in most modern ships at the moment, wastes are still dumped into the sea. These wastes directly cause massive damage in coral reef. Ships also have to avoid mooring in coral reef areas. Their anchors can cause serious damages on coral reef. Please read my post about this matter on an article entitled: Damage in coral reefs caused by anchoring.
I should emphasize that ships are not the only producers of wastes. Coastal towns and cities are the biggest producers of wastes. If we can stop dumping wastes both from the ships and the coastal towns and cities, more coral reef areas can be saved. Our marine environment will be better if millions of tons of wastes that are now floating at the surface of the seas or oceans can be removed.
