Environmental Impact of Coral Reefs - Coral reefs support up to 25% of all marine life, despite covering less than 1% of the ocean floor [3] - Coral reefs protect coasts from hurricanes, support economies through tourism and fishing, and regulate the global climate by storing carbon [3] - Rising ocean temperatures, even by one or two degrees, cause coral bleaching, leading to coral starvation and death [4] - Corals in contact with plastic have an 89% higher chance of contracting a disease [5] Potential Solutions - Coral gardening, involving growing coral fragments in underwater nurseries and transplanting them onto damaged reefs, shows great improvement in various locations [7] - Cloud brightening, spraying fine droplets of seawater into the sky to reflect sunlight, is being experimented with to cool oceans and help coral survive heat waves [8] - Reducing greenhouse gas emissions and plastic consumption globally is crucial for coral reef preservation [9] Call to Action - Support reef restoration through donations and volunteer work [11] - Raise awareness and promote action regarding coral reef conservation [11] - Choose reef-safe products, including sunscreen and seafood, to protect the oceans [11]

Environmental Impact & Risks - Coral reefs, vital ecosystems, are disappearing rapidly due to rising ocean temperatures [1][2] - A temperature increase of just 1 degree Celsius is devastating coral reefs that have existed for 500 million years [3] - Coral reefs, despite covering only 02% of the ocean floor, are home to 25% of all marine fish [4] - The world has witnessed a 50% decline in coral population over the past century [6] - Scientists predict that by 2050, coral populations could be gone if ocean conditions remain unchanged [6] Economic & Social Relevance - Coral reefs provide nurseries for fish, benefiting coastal communities [5] - They hold potential cures for diseases like cancer, acting as pharmacies [5] - Coral reefs act as storm shields, protecting against hurricanes, storms, and typhoons [5] Call to Action & Mitigation - Coral bleaching is occurring more frequently, every six years instead of every 25 years [9] - Individual actions, even small ones, can create significant change [11] - Spreading awareness about coral reefs is crucial for their conservation [12]
