Coral reefs offer more than just fascination for snorkelers and scubadivers, they also play into the economy. With seafood, tourism, and protection from storms, the reefs have a value of $375 billion. The reefs are currently in danger because of human practices. One factor that affects the sustainability of the coral reefs is pollution. We do not always realize it but we may be contributing to the pollution of oceans. Even if we do not live close to the ocean, things like streams and lakes carry pollutants toward the sea. Another way in which we affect coral reefs is through warming. The overuse of energy in businesses and in our homes has helped to change natural temperatures of the earth, forcing all other life to adapt. The last major cause of deteriorating coral reefs is a result of fishing practices. Because of advances in technology, fishermen are able to capture more sea life efficiently. Although this is good for their businesses, it disrupts the ecosystem. With all of these forces combined, coral reefs are at great risk. If we do not act soon to preserve the reefs their beauty and economic advantages will be lost.
