Another major environmental threat to coral reefs is pollution. Pollution can come from a wide array of sources and have a variety of adverse effects on coral reefs. Some common pollutants of coral reefs include sewage, silt, urban and industrial waste, oil, fertilizer runoff, pesticides and other chemicals. Common effects of these pollutants include overgrowth of algae and poisoning of the plants and animals within the reef (DuTemple, 45).
This is because many other species depends on its survival and their large influence in the ecosystem. Coral reef fisheries make up a large source of livelihood on Earth. In conclusion, to preserve the rich biodiversity of coral reef ecosystems and avoid robbing future generations of the ecosystem services coral reefs provide, the development of new, sustainable fishing methods and discontinuation of overfishing is necessary in order for coral reefs to survive.
This cause exists because of the warming and rising seas, the ocean acidification, overfishing, water ... ... middle of paper ... ... lived in the ocean. You can also be a responsible snorkeler, diver, swimmer or whale watcher. Coral reefs are very important! There are many books, educational movies and people who are trying to make the world be aware of the problems in our oceans. Anyone can start to help save the reefs by trying to stop all the harms that affect them and try to start using more energy efficient materials.
(“Coral Reef Protection: What Problems Exist?”) Coral reefs have a large significance in the world. The sensitivity of the coral polyps and the many creatures living inside the coral can show ocean water quality and if there are any significant changes in temperature, pH, salinity, and chemical makeup of the water. Reefs also protect the coasts and prevent erosion. In addition, coral reefs have also been shown to improve the economy from their status as a very popular tourist attraction. In conclusion, coral reefs have a large impact on the world in several ways.
Without proper conditions coral can bleach and die. People, water temperature, and other pollution in the water can severely hurt coral. Bleaching is now a big problem in coral reefs. Bleaching occurs when coral polyps lose their algae. When this happens they become transparent and you can see right through them to the skeleton, a bright white, hence the word “bleaching”.
Typically these giant cuttlefish will live in rocky reefs, sea grass beds, or areas of mud and sand (Elterman). Every year around May, they will migrate to the northern point of Spencer Gulf along about an 8km stretch of coast to mate during the Austral winter (Fowler). As they swim around preparing for the great aggregation, they show a preference to the fins that line their mantles and allow them to swim in any direction at their leisure rather than their siphons which would jet them in one direction (Elterman). They are diurnally active and will communicate with each other with their skin as they individually hunt (Elterman). They will often feed on different kinds of small fishes and many crustaceans, they especially love crustaceans (Elterman).
The Great Barrier Reef is a site of remarkable beauty and sea life. This reef holds the world’s largest collection of coral reefs with over 400 different types of coral, about 1,500 species of fish and 4,000 types of mollusk. The reef holds great scientific interest as the habitat of species such as the dugong or the sea cow and the large green turtle. This reef complex is one of the biological wonders of the world. Unfortunately, these biologically rich and sensitive communities take so long to recover from damage that it is estimated that, within 50 years, there will be no viable coral reefs anywhere, if we continue to destroy them.
Like other turtles, sea turtles lack teeth. Jaw shape varies among species. Each species has a jaw shape adapted for its diet. Sea turtles, depending on the species, may eat seagrasses, algae, sponges, sea squirts, squid, shrimp, crabs, jellyfish, cuttlefish or sea cucumbers. Leatherbacks can dive to a depth of more than 1,000 meters (3,000 feet) in search of their prey, jellyfish.
