Coral growth slows on Australia's Great Barrier Reef

Coral growth on Australia's Great Barrier Reef between 1990 and now has slowed. The coral is now growing at the lowest rate for over 400 years, according to researchers from the Australian Institute of Marine Biology.

This could pose numerous health threats to the species that live in the coral, which is the world's largest coral expanse. Coral reefs are home to many species of fish and other marine life, many of which aren't found any where else in the world. Coral reefs also protect coastlines, attract tourists, and are the potential source of many medicines.

The findings were reported in this article in Reuters.
