Loss of estimated 80-90% of coral species on Great Barrier Reef
Report 2. Line reef,hardy reef and hook reef 149 degrees east 20 degrees South. Northern End of Southern Barrier Reef.
No Words! Devastating loss of an estimated 80-90% of coral species! I saw a clown fish nibbling on a bleached coral bed and had to stop diving through sheer sadness
