The construction led to the destabilization of a unique ecosystem in the region.
Many species of flora and fauna face extinction because of landslides triggered by the erosion of the reservoir. Moreover, the dam generated a microclimate, with increased growth of algae.
Most types of steel melt between 1370°C (2500°F) and 1500°C (2732°F).
The melting temperature depends on its composition. In general, high-alloyed steels containing more alloying elements have higher melting points than low-alloyed steels.
China is the world's largest producer of steel. The country accounts for 57% of the world's production.
The European Union is the second largest producer and India is the third largest producer. Other major global steel producers are: Japan, USA, Russia, South Korea and Turkey.
