Coral reefs have been severely damaged by humans over the past century. If it were not for awareness and proactive solutions to conserving these reefs, there is a chance they could have been nearly lost altogether by now. This is just another example of why we need to follow the precautionary principle. That is, human actions must be proven to not be harmful to ecosystems. We cannot simply destroy natural areas because there is no obvious benefit to conserving the areas. Organisms such as coral reefs may prove to someday save human-kind, and we need to preserve biodiversity as much as possible so that we don't lose something that ends up being invaluable.
