The Corals Reefs--rainforest of the sea. Coral Reefs are the largest marine ecosystem and are facing soon extinction. Coral Reefs are defined as a ridge of rock in the sea formed by the growth and deposit of coral. Being the largest marine ecosystem, it is home to twenty-five percent of marine life (aprox. two million species), including sponges, sea anemones, fishes, crabs, and more. With its importance in marine life, its extinction is causing great worry. Due to global warming, coral bleaching is occurring. Coral bleaching is when sea water temperatures rise to cause the exponential growth of algae inside the coral reefs. As the algae grows, it covers the coral reefs, fish do not want to eat the algae, the algae continues to grow into a seaweed, killing both the coral reefs and small fish that no longer have food. As an ecosystem is a closely knit web connecting all species, the small fish which have died can no longer be a food supply for larger fish, causing the ecosystem to fall as each specie dies. Coral bleaching has long term effects, as algae spreads along the Coral Reef, causing death from coral predators and disease (coral predators are able to hurt coral reef as it becomes weaker from algae and disease). Even with the growth of new Coral Reefs or the recovery of the current Coral Reefs, it is inevitable that another major disturbance will occur. Unless we stop the our production of global warming (by recycling, not using of fossil fuels), the Coral Reefs can be saved.
This article is important as currently, we are facing one the most harmful extinctions caused by humans. This is just one of numerous endangerments of animals due to humans. Global warming is seen to be the reason for all detrimental effects of our Earth, raising the importance of why we need to take action and help reduce/end global warming.
