Transcript of The Mediterranean Sea

Mediterranean Sea The Ecosystem of the By Dawson Koerber The Mediterranean Sea is a body of water that is located between Southern Europe and North Africa. It's connected to 22 countries. It is composed of saltwater that comes in from the Atlantic Ocean. It spans over 2 500 000 km2 and it's greatest depth is 5 267m (average depth is 1 500m). The Nile River empties into the Mediterranean Sea. http://static3.depositphotos.com/1000746/134/i/450/dep_1348632-Italian-Mediterranean-sea-coast.jpg photos http://upload.wikimedia.org/wikipedia/commons/thumb/d/d8/Mediterranean_Sea_political_map-en.svg/240px-Mediterranean_Sea_political_map-en.svg.png sources Wikipedia http://www.bbc.co.uk/nature/places/Mediterranean_Basin http://www.bbc.co.uk/nature/life Wildlife Stoats Kingfishers Flying Fish Stingrays Neptune Grass http://2.bp.blogspot.com/_OWTdPm5dguk/TO-joO6AznI/AAAAAAAAAjM/poD0rpsLnjI/s320/Neptune%2BGrass.jpeg A Stoat is a member of the Weasel Family that lives in the the Northern Hemisphere. The Stoat is a skillful predator that hunts small animals such as rabbits, birds, rodents and berries. During the winter a Stoat's fur will change too a bright white except for it's tail which will stay black. This white fur is called Ermine. Ermine fur is a prized possession in the fur trade for in Europe it is a symbol of royalty and high status. http://imagecache6.allposters.com/LRG/37/3783/C48IF00Z.jpg Stoats are adapted to living in the Mediterranean Basin because they are able to climb trees to get at bird's nests and also because they have a slender body and they're very quick so they can easily chase rodents through tunnels. One last adaption is that rabbits are part of a Stoat's diet and rabbits multiply quickly so there is plenty of food for the Stoats to eat. Stingrays are a species of Rays that are related to sharks. Their bodies are flat and they have disc shaped fins. They have a barbed stinger on there tail (hence the name Stingray) that is only used in self-defence (like when they're stepped on). There diet consists of worms, squid, crustaceans (crab, lobster, crayfish, shrimp, etc.) and carrion (dead animal). Stingrays are adapted to the Mediterranean Sea because their flat bodies can be used to bury themselves in the sand. This is where the live and how they hide.

The mouth of a Stingray is located on it's underside which allows it dig crustaceans out of the sea bed. Their mouths house several rows of blunt, broad teeth which are used to crack open shells. Kingfishers are a species of birds that live in the Mediterranean Basin. They look very colourful but their feathers are actually a murky brown. The reason for this is that when the white beams of the sun hits the Kingfisher's feathers the only colour absorbed by the feathers is blue. In conclusion a Kingfisher in the sun is blue while a Kingfisher in the dark is brown. This bird's diet consists of small fish and aquatic insects. The Kingfisher is adapted to the Mediterranean Basin because it has a shorter wingspan which allows it to dive quicker and more effectively. This works in cooperation with its long, sharp beak for it allows the Kingfisher to pierce right through a fish. Neptune Grass is a aquatic plant that is only found in the Mediterranean. It creates meadows in the clear, shallow waters of the Mediterranean Sea. It may be one of the oldest lifeforms on Earth. http://eol.org/pages/1089001/details http://www.bbc.co.uk/nature/ Neptune Grass is adapted to the Mediterranean Sea because it is home to many marine organisms. Flying Fish are a species of fish that live in oceans and seas. Due to it's wing shaped fins Flying Fish are able to glide in the air. To get into the air a Flying Fish moves it's tail up to speeds of 70 flips/second. On average they will glide for 50 metres but they have been recorded to glide for up to 400 metres. Their diet consists of plankton and small crustaceans http://en.wikipedia.org/wiki/File:Pink-wing_flying_fish.jpg http://www.buzzle.com/articles/flying-fish.html Flying Fish are adapted to the Mediterranean Sea because of their ability to glide. The reason that they glide is to escape from their predators. When they are being pursued they will speed up right below the surface and then they will launch themselves out of the water before they 're caught . http://www.travelblog.org/Photos/6216882 http://www.dailymail.co.uk/sciencetech/article-1133589/Dinner-It-8217-s-fast-food-deep-freeze.html http://www.art.com/products/p14307605-sa-i2917678/paul-kay-neptune-grass-maltese-island.htm Human Interaction Pollution The Mediterranean Sea is very polluted. One reason for this is that it is a major oil transportation route. Over 1 000 000 tons of oil are spilled annually into the Sea. http://www.explorecrete.com/nature/mediterranean.html The area around the Mediterranean Sea used to be surrounded by forest but human settlement has greatly reduced the forest cover. Now only about 5% of the Mediterranean Basin is covered in forest. These are located primarily on the northern shore. Archeologist have discovered remains that prove the fact that at some point in time the Basin was home to many lush forests. Most of these locations are now home shrubs and desert. The forest were quite important as they protected the fragile soil from dry spells and water erosion (water removing soil creating things such as rills and gulleys witch are basically just trenches) caused by torrential (lots of rain falling rapid) rainfalls. But now because of us Humans those forests are gone. It has been estimated that every year these following
items are dumped in the Mediterranean Sea.

-650 million tons of sewage
-129,000 tons of mineral oil
-60,000 tons of mercury
-3,800 tons of lead
-36,000 tons of phosphates (inorganic chemical)

In addition to this, 70% of the waste water that is dumped into the Mediterranean is untreated. Every year there are more than 100 million tourists (that`s pretty much the whole country of Mexico) who travel to Mediterranean beaches. And how do we cater to all these peoples needs and wants? Why we tear down these beautiful natural habitats that surround the area and replaced them with resorts. Breeding and nesting sites that have been used by animals since who knows when, have been destroyed by us and replaced by tourist facilities. Thus, we have endangered many species of animals, the most notable is the loggerhead sea turtle. We would wipe out an entire species, just so you can buy a pair of tacky Stingray slippers. These resorts also generate more pollution, that often dumped untreated into the sea. http://ens-newswire.com/ens/oct2006/20061004_sewage.jpg http://electronicintifada.net/sites/electronicintifada.net/files/artman2/1/polluted-coast.jpg http://www.destination360.com/europe/spain/images/s/marbella-resorts.jpg http://www.soilerosion.net/image/hillslope_rills.jpg http://www.science-art.com/gallery/109/109_452005211430.jpg http://www.shoppingblog.com/pics/sea_world_baby_turtles_0909.jpg http://www.divephotoguide.com/images/photos/b/69_1223343554.jpg Since the Mediterranean Sea is where the Rivers Po, Ebro, Nile and Rhone complete there journey they bring with them not only their water but the agricultural and industrial wastes carried down with it. Then when the sun evaporates the water what gets left behind... that's right the waste. Since the Mediterranean Sea is almost landlocked it will hold that waste for a very long time. Even if does get out the only place it can go is the Atlantic Ocean. http://www.greenpeace.org/international/PageFiles/24687/sea-otter-at-rehabilitation-ce.jpg Otters get really pissed off when they have to a human scrub oil off of there fur. Grrrrr http://www.funnytimes.com/archives/files/art/19981104.jpg Bibliography Why you kill my species?! So to wrap this up the Mediterranean Sea is a saltwater body of water which receives it water mainly from the Atlantic Ocean. It is very polluted and humans have effected it greatly. It home to various types of wildlife such as Stoats, Kingfishers, Stingrays, Flying Fish and Neptune Grass. So Thank You for listening and I'll finish of with a video. http://i.chzbgr.com/completestore/2009/7/12/128919173409046353.jpg
