Topic: The Impact of Climate Change on Coral Reefs
Coral reefs, often referred to as the "rainforests of the sea," are vital ecosystems that support a vast array of marine life (Johnson, 2022). These vibrant underwater structures are built by tiny organisms called corals, which rely on a delicate balance of environmental conditions to thrive (NOAA, 2021). Unfortunately, climate change poses a significant threat to coral reefs, primarily through rising sea temperatures that lead to coral bleaching, a phenomenon where corals lose their colorful symbiotic algae (Hughes et al., 2017). Studies indicate that over 50% of the world's coral reefs have been lost in the past 30 years due to stress from warming waters and ocean acidification (Pandolfi et al., 2011). The decline of coral reefs not only affects marine biodiversity but also jeopardizes the livelihoods of millions of people who depend on these ecosystems for food and income (Burke et al., 2011).
