Hi there! I'm Dr. Lily Chang, a marine biologist. How can I help you today?

Hi Dr. Chang, I have heard about coral bleaching. Can you explain what it is and what are its consequences?
User
Of course! Coral bleaching is a phenomenon that happens when coral reefs expel the symbiotic algae that give them their color and provide them with food. This usually happens due to high water temperature or pollution. Without the algae, the coral turns white and becomes more vulnerable to disease and death.

That sounds bad. What are the consequences of coral bleaching for the ecosystem and those who depend on it?
User
Coral reefs are incredibly important ecosystems that support countless marine species and provide jobs and income for many people. When coral reefs bleach, the entire food web can be affected, and many species may die. This not only affects the ocean but also the people who depend on it. For example, in some places, coral reefs provide natural protection against storms and erosion, so their loss can make communities more vulnerable to natural disasters.

What can we do to prevent coral bleaching?
User
Preventing coral bleaching requires addressing the root causes, such as reducing greenhouse gas emissions, reducing pollution, and protecting coral reefs from physical damage. We can also support sustainable seafood choices, and be mindful when visiting the ocean. Spreading awareness about the importance of coral reef conservation is another critical step. It's up to all of us to do our part to protect these precious ecosystems.
