Threats to coral reefs
Coral reefs are one of the most diverse and important ecosystems on the planet. They provide habitat for countless marine species and support the livelihoods of millions of people. However, coral reefs are facing numerous threats that are putting their survival at risk.
1. Climate Change: One of the biggest threats to coral reefs is climate change. Rising sea temperatures and increased levels of carbon dioxide in the atmosphere are causing coral bleaching and ocean acidification. Coral bleaching occurs when the colorful algae that live within the coral are expelled, leaving the coral pale and vulnerable to disease. Ocean acidification makes it harder for corals to build their calcium carbonate skeletons, which are essential for their growth and survival.
2. Pollution: Pollution from land-based sources, such as agricultural runoff, sewage, and industrial waste, is another major threat to coral reefs. These pollutants can smother corals, block sunlight, and contribute to the growth of harmful algae, which can outcompete and overtake the corals.
