 to explain how climate change is damaging the delicate ecosystem in coral reefs

Explanation:

The author mentions the Coral reefs in the article to call attention to how climate change is damaging the delicate ecosystem of the Coral reefs. This is because the current trend of climate change is leading to warmer oceans and when that happens, Coral reefs die.

This creates problems because Coral reefs protect the shoreline and are a habitat for fish which means that if they die, shorelines are in danger, fish would die off or move away which would then have the effect of reducing the income stream of fishermen.
