Explanation:

[STC001986] The warming of the ocean, which is one aspect of climate change, has had a significant impact on the way of life of the Great Barrier Reef in Australia as well as coral in other parts of the world. The bleaching effect is caused by warming in turn. According to CBS News, white coral develops after the damaged organism rids itself of its symbiotic algae, which serves as the coral’s primary source of nutrition. When this occurs, the coral is unable to replenish its supplies and begins to suffer as a result. There are thousands of different species that have been left without a home and without food since the dominant species of coral in the Barrier Reef has been drastically depleted. According to CBS News, there was a fall of 89 percent in the number of baby corals in 2019. Scientists are hopeful of rebirth only if warming and mass bleaching events slow down or stop within a large span of time.
