New Delhi: Tim Kopra, NASA astronaut yet again mesmerized his followers with his latest tweet of a beautiful image of Caribbean coral reefs from space.

Coral reefs are the main victims of sudden climate change. They are vanishing at alarming rate due to ocean acidification and global warming.

Being guardian of marine ecosystem, they provide protective shelter for different species of fish and also check the balance of carbon dioxide in ocean water.

But the future is not looking bright for these diverse underwater ecosystem. Many environmentalists fear that these beautiful coral reefs could vanish in the next 20 years.

The pic shared by US astronaut not only gives great aesthetic pleasure but also delivers a strong message- save the coral cover before they are gone .
