CORAL BLEACHING CAUSED BY GLOBAL WARMING

CORALS BEFORE BLEACHING
CORALS AFTER BLEACHING

CORAL BLEACHING means whitening of the corals, this is due to the symbiotic algae which live on it leave it.

The reason behind is GLOBAL WARMING.

The temperature under the water is found to be around 34 degree centigrade, which is around 3-4 degree greater than the normal water temperature.

This rise in temperature has lead to coral bleaching, which in turn has resulted in death of around 80% of the species.

If this continues then coral would be completely bleached within few months.

This is mainly found near Indonesia.

These losses in coral will affect the food chain of the aquatic life, also will increase the under water temperature.

This will result in various natural calamities, which will affect everyone.

So we have to bring back coral reefs so that the under water temperature remains steady and also the aquatic food chain is not affected.
