Belonging to the Sirenia establishment of mammalians, manatees are the common name for a immense, gray or ebon air aware water mammal. Sometimes called a sea cow, the manatee looks tolerably like a hippopotamus. Cuddly manatees have mammoth populace averaging ten feet in twist and weighing between 440 and 1300 pounds. Manatees have a unpretentious head with a straight snout having a bristly moustache on the extreme remark. Paddle - like forelimbs are used to procedure through the water.

Manatees live in fresh, spicy, or flavour water and roam with cramped herds rather like a family. Six to eight hours a future is spent grazing upon seaweed and other maritime plants. Their slow metabolism reduces the energy requirements, forasmuch as they move slowly through the water. Thanks to of their size, manatees have few natural enemies. Humans are the primary threat to the health and safety of the manatees. Neighboring a 12 - while maturation title, the female manatee may give birth to a single, carmine kid about once every three years. A immeasurable may nurse her nipper from her teats located under her pectoral flippers.

Why Protect the Manatees?

The extinction of one or more sort may affect the ecosystem and originate irreversibly damage. For quotation, when sea otters near the northern Propitiatory Rim were easy make nearly to extinction in the 19th and early 20th centuries, sea juvenile no longer had a exceeding predator. This caused the sea teenybopper community to upturn inordinately. Once the sea urchins ate the kelp and other seaweeds, the easy underwater ecosystem became barren. When the U. S Seagoing Mammal Act of 1972 set diffuse questioning laws, sea otters were reintroduced to the area. The kelp and seaweed forests were restored.

Humans depend upon the ecosystems to give food, water, and clean air, as fit as many medicines and wares that are provided by biodiversity. It is imperative that we protect and save the lives of endangered plants and animals.

Typically manatees are endow in the burning and subtropical waters of North and South America and Africa, and are not native to the coasts of Florida. The Florida manatees are sub - genus of the West Indian manatee brought to the coasts of Florida in the 1700s. Forasmuch as called sea stock, they were kept in netted close water corrals and raised as a food source. When these mammals were released, many died from water temperatures that were too cool, and from boating collisions. Manatees ared herbivores, and eat a diversification of sixty or more sea grasses and plants. Conservation efforts are supported by the detail that manatees sunshiny plant - clogged river channels used for irrigation and transportation. Hence, manatees are unharmed by local and national legislation in every coastal county in Florida. The State strictly enforces speed restrictions in manatee habitats to protect the singular sea mammals from boating collisions. Still 26 % of manatee deaths are caused by collisions with watercrafts.

According to Save the Manatee Club, Manatees are currently independent total extinction. In 1996 midpoint 20 % of the world ' s entire manatee nationality died. Without storming, the animal faces a high risk of extinction in the untouched in ten or more years ( The World Conservation Union, IUCN ).

The main causes of manatee death are human - related twin as harrassment, poaching for hides, meat, and blubber oil, entanglement in Flood Gate or Canal Lock; habitat destruction; and deaths caused from fishing line, litter, vandalism, culverts and other man - made structures. Other causes of manatee death are natural causes same as sharp water temperatures, stress, salmon tide, sickness, and calving difficulties.

Harassment refers to pursuing, chasing, poking, prodding, grabbing, riding, and feeding manatees or giving them water from a douse. This conditions them to take food or water from people. Some people may use this shot to feed them speculative non - food items or harm the manatee in some way. Harassment by boaters, divers, swimmers, and people fishing can stimulus manatees to consent larger habitat consistent as sunny water refuges. Harassment can also lead to separation of oversize and teenager. Save the Manatee® Club supports passive observation ( observing from a distance ) as the onliest way to interact with manatees and all wildlife.

Jim Waymer reports that according to Florida charge endangered manatees are dissolution at the rate of one per tide. Sailing vigil dean, Dennis Harrah, estimated in June 2000 that only 2, 200 remained alive in Florida waters. Harrah has watched for 24 years as the manatees drift toward extinction.

Law enforcement has issued 67 citations and 37 warnings for boaters who ignored the manatee zones in Brevard County during the challenge period. Of those numbers, 42 of the citations and 27 of the warnings were issued to county residents who were aware of where the speed zones are located.

In spite of fines and penalties harrassment by humans continues to be an issue. Hundreds of boaters protested a judge’s ruling and the new manatee slow speed ruling by sounding their horns ( a form of manatee harassment ) while cruising through the Barge Canal which provides access from Merritt Island to the Banana River and the Indian River Lagoon. These boaters felt that the new laws were jeopardizing their safety and violating their rights without actually protecting the manatees. Protection of endangered species is vital to the continued existence of harmony in our environment. There is something every human can do to insure that our planet continues to thrive. The process begins with the help of citizens, but must be enforced by federal, state, and local laws.

On May 12, 2007, Protherics, a pharmaceutical company with aid in Brentwood, Tennessee and London, England, announced that their new vaccine for the treatment of high blood pressure is flash cheering influence in clinical trouble. ( 1 )

Blood pressure regulation within the body is a mosaic system. The primary authority mechanism is through the “renin - angiotensin” system, a cataract of hormones produced in the kidneys. When the enzyme renin is released from the kidneys, it attaches to angiotensinin, a protein initiate in the blood. Once attached, angiotensinin is converted to an intermediate compound called angiotensin I ( AT1 ). This atom is further converted to the active mold called angiotensin II ( AT2 ). When this deluge is overactive, hypertension ( high blood pressure ) is the settlement. AT2 can inimitably constrict blood vessels during times of stress, shifting the blood flow from the extremities to vital organs. Protherics vaccine, called Angiotensin Therapeutic Vaccine, is designed to induce antibodies that will murder AT1. Without AT1, there can be no AT2. The planned eventuality is common blood pressure.

On first blush, the image of a vaccine to subjection high blood pressure sounds like a good notion. Many patients fail to take their prescribed medicines, much being they do not like the side effects or thanks to they can’t dispense the drugs. As a end, it is estimated that midpoint 70 % patients with hypertension suffer from complications, including the preference of a heart volley or a stroke.

For Protherics, the positive outcropping from its clinical trial has potentially enormous economic ramifications. Recent data shows that the market for high blood pressure medication is worth approximately US$36 billion per annum. ( 2 ) The Company hopes that a vaccine inured every few months will improve charge of blood mild to moderate pressure by increasing empathetic compliance. Protherics is developing an more suitable management that will interject a “novel vaccine adjuvant” and will maintain its human blow throughout 2007. If all goes right, Protherics plans to start licensing the vaccine to manufacturing pair closest the new tragedy have been nailed down.

But before rushing to the doctor, the consequences of manipulating the AT1 - AT2 system by a vaccine need to be considered. Within the foregone two decades, a great deal has been learned about the renin - angiotensin system in other parts of the body. It has been discovered that the brain further produces angiotension peptides and depends on these molecules for high function. AT1 and AT2 in the brain are obligated for the regulation of blood flow to the brain tissue, cognition, learning, behavior, recapture and regulation of emotional responses. ( 3 ) ( 4 ) ( 5 ) It is not proclaimed if the vaccine will petulant the blood - brain barrier and generate dysfunction of the brain renin - angiotensin system.

The skin is further instanter affected by angiotensin peptides. It has been remarkably demonstrated that AT2 plays an relevant role in slash remedial. ( 6 ) A vaccine that blocks the formation of AT2 may seriously effect the endowment for the skin to repair and treat next an injury.
There are simple, natural ways to lower your blood pressure. Foundation by maintaining your nonpareil body weight, exercising usually, getting totally of sleep and keeping well - hydrated. Be very cautious before agreeing to be vaccinated for blood pressure control.
