Coral Reefs are remarkable natural occurrences which host nearly one quarter of marine life in the oceans. Coral is low nutrient areas of the tropics and provides a home for fish, invertebrates, mollusks and other sea life. Entire ecosystems spring up from the ocean floor. Unfortunately coral reefs are in danger as a number of factors make it harder for coral to grow and survive. Coral reefs are strained by rising ocean temperatures, increasing ocean acidity levels, pollution from human communities and overfishing.
This affirmative case outlines to advantages to preserving coral reefs. First, is maintaining the biodiversity of the oceans. Healthy coral reefs provide the basis of large and varied ecosystems that sustain life throughout the oceans. Additionally, humans who live near coral reefs depend on the sea life living on the reef for food and their local economy. Secondly, coral reefs are a source for medical discoveries. Coral reefs are homes to many rare species that could offer cures to diseases. Diseases kill millions yearly. HIV is one of the largest killers worldwide and new discoveries from coral have offered a possible way to prevent infection.
The affirmative plan is to build artificial reefs and the regrow reefs where possible. A new technology called Biorock allows for coral to be regrown on living coral reefs by using electrical currents to stimulate growth. Artificial reefs can also be used to mimic the benefits of coral reefs and restore biodiversity to areas that fish have left.
