The Great Barrier Reef- resistant coral

[Dave_S]

Just watched a documentary about coral bleaching.

They believe the coral dies because the bacteria that live in the coral that provide 95% of the needed nutrition. They say the bacteria are not able to survive the change in temp and release a chemical when stressed that the coral expells with the bacteria and die.

They are working on bacteria resistant to the heat change and new strains of coral that can survive. They believe the temperature will max out around the year 2050, they are trying and succeeding in creating coral and bacteria that can survive in the expected maximum temps.

Question is should they introduce them to the reef ?

They concede cross breeding corals will result in less coral variety and GM bacteria, ........ who knows what the outcome might be.

History shows the reef will come back, not sure when, or if it will in fact go, I suspect not.

Should we interfere, should we try to keep things the same or let them change.

Will this be another cane toad or crown of thorns mistake?

Tricky questions with unconfirmed premises.

Interested to hear thoughts.
