IELTS Listening Sentence Completion | Example 3

One of the most fascinating aspects of marine biology is the behavior of coral reefs. Coral reefs are often referred to as the rainforests of the sea because of their incredible biodiversity. They support thousands of marine species, including fish, crustaceans, and algae.

Unfortunately, coral reefs are under threat due to climate change. Rising ocean temperatures cause coral bleaching, where corals lose the algae that give them color and nutrients. This can lead to the death of entire reef systems.

Conservation efforts are underway to protect these ecosystems. Marine protected areas have been established to limit fishing and other activities that harm coral reefs. Additionally, scientists are working on ways to make corals more resilient to warming oceans.
