The helpful practice of coral breeding is such that corals that thrive in warmer climates may be bred with cooler varieties in order to allow the cooler ones to survive the warm weather that lies ahead.
Corals surviving in hot waters are to be bred with those corals that are used to cooler temperatures. This is so that the cooler ones can get used to warmer climates. As global warming gets hot and hotter with the changing times, this has become a necessity.

Corals are found in Australia’s Great Barrier Reef where the water temperatures are pretty warm. These special corals are more amenable to warmth and rising fluctuations in temperature than other varieties. Similar types found in the sea about 300 miles southwards are a cooler kind indeed.
This study has set off a movement to consciously breed corals so that they become heatproof in the future. It will all take place on a genetic level as the genes that are susceptible to heat strain get weeded out while those genes that are heat-resistant will burgeon and flourish thanks to the timely intervention by mankind.
Baby coral from the north where the sea was about two degrees centigrade higher in temperature thrived whereas the southern variety simply could not withstand the heat.
Corals, as everybody knows, are solid patterned living creatures that are like stones. They serve as food for fish and also are a very picturesque proposal for deep sea divers. The cross-breeding of corals is a whole new project that it is hoped will show success on a massive scale.
Corals are disappearing fast and something has to be done to preserve them. For one thing, the ocean waters are becoming hotter and hotter. Thus their very survival has been put into jeopardy.
The fact that they can be bred to be heat-tolerant should not be thought of as a single nostrum that is the panacea to all problems. Rather other methods of preservation ought to be taken into consideration too. Time is of the essence since nothing is ours except time.
Before it is too late, the conservation efforts ought to get underway. Another thing which has to be kept in mind is that sometimes good actions have unintended consequences.
The shifting of corals and their re-breeding human-style may cause an imbalance in the flora and fauna of various regions thereby upsetting the delicate ecological web. Therefore, this is something that needs looking into too.
