The mining disaster

Critics to the practice of mine waste (tailing) to the rivers and other waters, the mining company to sea disposal technique (method of sub-marine tailings disposal ). In addition to its impact can be seen that happen, the method of disposal tails to the sea is much cheaper in terms of costs. They also promote that this method is a safe method with the assumption that the sea there is a layer tails and not to settle on the surface

As an archipelago country in the world, with more than 17,500 islands and shoreline along the 80,000 km, the Indonesia is a place of life and source of marine biological with the type of the richest coral reefs in the world (Wilkinson, 2000) .

Tailing waste already known plural contain many toxic substances that come from rock and oxidation reactions of the chemicals used in the process of separation of ore. Tailing disposal to the sea will cause sedimentation of sludge tails and tails of the distribution of sea area to the more knowledge. All these effects will be more likely to destroy the wealth and diversity of marine biodiversity, health and the poorer coastal communities and small islands are heavily dependent on the sea.

Moreover, 78% in the waters of the sea is shallow, the method of the sub-marine tailings disposal is also a high risk of contamination of the sea. The position of the Indonesian archipelago, which lies between the Indian Ocean and Pacific Ocean, the dynamics of Indonesia has a very high, which also affect the wealth of biodiversity sea, and the dynamics of the physical condition of the sea, such as the existence of the phenomenon and low vertical column mixing seawater (up-Welling).
