Recommended: Manatee preservation introduction
Everyone loves the Florida manatee because they look like big puppy dogs with a cute endless smile. In addition, they are beautiful creatures that bring a smile to every face that sees them floating along in their natural habitat or in the local aquarium. Undoubtedly, the Florida manatee is one of the friendliest species in the world even though they are huge animals weighing up to twelve hundred pounds and reaching ten-foot long. Despite what this gentle creature has been through at the hands of human beings, the Florida manatee looks as happy as ever when they are sighted feeding in their natural environment. However, the manatee population is being threatened and needs help to prevent further decline. The reduction in the Florida manatee …show more content…
population is a result of human disregard and red tide, but lawmakers, researchers, and by the participation of some boaters have helped preserve the gentle giants. Unfortunately, human interaction and red tide have played a significant role in the decline of the Florida manatee population.
In the nineteenth century, the Florida manatee population started to decline in numbers due to settlers hunting them for their meat (Pittman 15). In addition, during that time some of the scientists started to notice a decline in manatee sightings in areas they were known to migrate. Since permits were being granted to kill Florida manatees for science, and poachers were hunting them for their meat, government officials and researchers were concerned for the manatee's future (Pittman 17). Currently, there are many factors the Florida manatee is facing that poses a threat to their existence. Unfortunately, the greatest threat to the Florida manatee in the twenty-first century is boating and the loss of their natural habitat (McAullife 18). In fact, many boaters who have businesses have protested that their businesses are more important than the clumsy animals. Currently, another public concern for the Florida manatee is the increase of toxic blooms that cause red tide. In addition, since records have been kept researchers have discovered that red tide has been playing a role in the decline of the Florida manatee as well (Raloff 56). Red tide is a form of many toxins that are consumed by the manatee when they feed on seagrasses causing lung …show more content…
paralysis. Furthermore, as a result of human disregard, the Florida manatee has lost habitat and suffered in their numbers. During the nineteenth century, settlers did not only hunt Florida manatees for their sweet tasting meat, but they hunted them for their bones, which is hard like ivory and great for making weapons and tools (Pittman 15). Another problem that was taking place during that time was many of the manatee specimens were being taxidermized and put on display in local museums. Moreover, killing Florida manatees for the sake of science was causing additional losses in their numbers. Consequently, the permits granted for studies helped aide in the process of endangerment (Pittman 17). Although restrictions were put in place, manatees continue to be endangered in the twenty-first century. Currently, the Florida manatee is facing an uncertain future because of the loss of their natural habitat by land developers and collisions by boaters. Undoubtedly, what is left of the areas the Florida manatee migrates to is lacking in speeding wake zones. Kathleen McAullife points out in her article, "Saving Manatees" boating collisions killed one-quarter of the Florida manatee population alone in 1999 (18). However, much of the Florida manatee habitat has been overdeveloped by local construction companies, which have caused interruptions in their natural migration patterns. In addition, many of the Florida manatees today wear scars on their backs as a result of boater collisions. Furthermore, according to The Save the Manatee Club, "Boating collisions and habitat destructions are causing the Florida manatee to sink further towards extinction" (qtd Pittman 231). On the other hand, another threat the Florida manatee is facing currently as a result of human interaction is red tide. For example, according to Janet Raloff, an increase in the worlds ocean traffic may be playing a role in frequent red tide blooms (56). Red tide is a toxic cocktail of microorganisms that has caused many deaths in the Florida manatee population. Although the Florida manatee has had many misfortunes, some people are trying to make a difference for the friendly creatures. Assuredly, researchers and Florida lawmakers have been working on solutions to increase the Florida manatee population.
Clearly, when local politicians and researchers saw that the Florida manatee population was decreasing back in the nineteenth century, they decided to present a bill to The House of Representatives to protect the manatees from being killed. For example, on April 4, 1893, the state passed House Bill 295, "An act to protect the manatee" (Pittman 16). As a result, the Florida manatee is protected from being hunted or killed for the sake of science in the State of Florida. Currently, in the twenty-first century, researchers have been studying Florida manatee migration to help state lawmakers apply wake zones to prevent fewer boater collisions with the species (McAuliffe 18). Furthermore, the outcome of the manatee migration study has helped boating problems that exist today to be somewhat successful. Due to the wake zones implemented by the state, boater participation has resulted in fewer annual Florida manatee deaths since 2007 ( Pittman 364). In addition to the boating problem today, many researchers believe increased ocean traffic may be causing frequent red tide recurrences. Janet Raloff points out in "Toxic Surfs" that a decrease in the worlds ocean traffic may reduce red tide (56). Undoubtedly, this may be the hardest solution yet in helping the Florida manatee survive because it involves compliance with the world and not just Florida
citizens. On the other hand, the Florida manatee population can be increased and preserved if government agencies and Florida citizens work together to do what we can. Although humankind has been negligent in the past and present, we can make a difference in the outcome for the Florida manatee's future by abiding by boating laws set in place by the state. Furthermore, it is our duty to educate the rest of the world on current issues causing frequent red tide recurrences like the increased ocean traffic problems. Fortunately, the Florida manatee has no known underwater predators affecting their numbers other than humans, so if we can stop human interaction the Florida manatee population will grow. Finally, although the Florida manatee population has suffered in the past years due to human disregard and red tide blooms, thanks to lawmakers, researchers, and boater participation we are making an advancement.
Seaworld is a giant marine life theme park. The greatest attraction to these many theme park would be those killer whales. In fact, these killer whales are the face of the park. As gigant as these mammals are, seaworld is keeping them in some pretty tight quarters. Mr. Jett and Mr.Ventre says “Wild killer whales can swim a hundred miles daily as they socialize, forage, communicate, and breed. In stark contrast, with little horizontal or vertical space in their enclosures, captive orcas swim only limited distances, with most spending many hours surface resting.” The animals don't have the freedom they need. Also when taking the whales out of their natural habit the whales tend to be depressed and not as heath in that situation. They need their freedom in the big ocean blue. Bring them into the small living units, breeding whales in captivity all for the entertainment of humans. At young ages the calves are taken away from their mothers on to a new seaworld park. Mothers of the calves have even been seen denying their offspring.
The State of Florida’s marine ecosystems are in a constant pattern of change. Change is necessary in nature. Change is nature’s way of adaptation. While there are “occasional good” changes, the progressive major changes have a devastating negative impact to the Florida marine environment. There are several factors correlated directly to this negative change. Most of these factors are due to man. One cause is natural. It is the hurricane. Hurricane Season is from June to November (NOAA) each and every year. On average 11 named storms occur in the Atlantic Basin each year with 6 reaching hurricane strength and 50% of these becoming a major hurricane of category 3 to 5 on the Saffir-Simpson Hurricane Scale (NOAA). Whether small or large, hurricanes cause damage and modifica...

Within the state of Florida there are dozens of individualized, non-profit organizations making an effort to help the local wildlife. The local land and marine wildlife includes birds, geckos, frogs, snakes, panthers, manatees, sea turtles, fishes, sharks, corals, lizards and many, many more. Florida State is located on the Southeastern tip of the United States providing a unique opportunity for conservation of salt-water animals. While there are animal conservation efforts taking place all over the world, this essay will focus on two animal species that humans are specifically trying to save in Florida State. The two main animal species of focus are manatees and sea turtles.
The Chesapeake Bay is the nation’s largest estuary with six major tributaries, the James, the Potomac, the Susquehanna, the Patuxent, the York, and the Rappahannock Rivers, feeding into the bay from various locations in Maryland, Virginia, Pennsylvania, and the District of Columbia (Chemical Contaminants in the Chesapeake Bay – Workshop Discussion 1). These areas depend on the Bay as both an environmental and an economic resource. Throughout the last 15 years the Chesapeake Bay has suffered from elevated levels of pollution. Nitrogen and phosphorous from wastewater treatment plants, farmland, air pollution, and development all lead to reduced water clarity and lowered oxygen levels, which harm fish, crabs, oysters and underwater grasses (Key Commission Issues 1). There are other types of pollution in the bay such as toxic chemicals, but because nutrient pollution is the most significant and most widespread in the Bay its effects are the most harmful to fisheries. Nitrogen and phosphorous fuel algal blooms which cloud the water and block sunlight from reaching underwater grass beds that provide food and habitat for waterfowl, juvenile fish, blue crabs, and other species (Blankenship 11-12). Algae plays a vital role in the food chain by providing food for small fish and oysters. However, when there is an overabundance of algae it dies, sinks to the bottom of the Bay, and decomposes in such a manner that depletes the oxygen levels of the Bay (11). The reduced oxygen levels in the Bay reduce the carrying capacity of the environment and these “dead areas” sometimes kill off species that can not migrate to other areas of the Bay, such as oysters (11). Increased abundance of algal blooms also led to the overabundance of harmful and toxic algae species and microbes such as the microbe Pfiesteria, which was responsible in 1997 for eating fish alive and making dozens of people sick (12). The heightened awareness of diseases that can be contracted through consumption of contaminated fish also has an economic impact. Therefore, the excess levels of nitrogen and phosphorous have fueled an overabundance of algal blooms, which has reduced water clarity and lowered oxygen levels, affecting many species within the bay and ultimately the industries that rely on these species.
The manatee has been on the endangered species list since the year. 2001. The 'Secondary' of the 'Secondary' This is caused by pollution in the water, power boats, and slow reproductivity. The symbiosis of the symbiosis. As a result, humans are putting an effort into saving these seas.
Maintaining ecological diversity is necessary for the survival of a biological community. In the United States, American citizens are on the verge of irrevocably damaging one of the country's most unique and diverse treasures - the Florida Everglades. This national park is now the only remaining patch of a river that used to span 120 miles from Lake Okeechobee to the Florida Bay. Dikes and levees created by the Army Corps of Engineers in the late 1940's drained this river to reduce flooding and increase useable water for the development of the region. This major diversion of water lead to a trickle down effect causing the continual decline of the environmental state of the Everglades. Since then, debates over the Everglades' future have silently raged on for years about how, why, and when the restoration will begin. This ongoing, but virtually unproductive effort has cost taxpayers a great deal without any apparent benefits. Recently, this debate has been amplified by the voices of the sugar industry in Florida, which was attacked for its major contribution to pollution of the Everglades. Now debates rage on with a new effort called the Restudy. Backed by the Army Corps of Engineers, this effort would change the flow of the Everglades, potentially restoring it into the viable community of life that it used to be. The question now is, will this latest attempt to restore the Everglades ever be realized (thus ending the cyclic Everglades debate) or will it simply add up to one more notch on the bedpost of inadequate and failed attempts to save this national treasure. The world is watching to see how the United States will handle this unprecedented cleanup.
The Chesapeake Bay plays host to an astonishing amount of plant and animal life, providing much of our fish intake for species that aren’t being overfished. For the species that are being overdrawn, the Chesapeake Bay Foundation is working to restore the populations, and it’s going well thus far. Another theme that is endangering the marine life populations as well as the health of the human population is the massive amount of polluti...
SSSSS!! "There's a snake!" Welcome to the most fascinating place in the world, the Florida everglades.It's values are very important , it helps the plants ad animals have habitats, food, and places to live.It also helps lots of humans in Florida with water supplies.
Manatees are loved by many Floridians. Manatees are known as one of the state’s natural wonders. They were once marked as one of the endangered mammals in Florida. The federal government considers a species endangered when it is at risk of extinction. Therefore, the federal government is downlisting manatees from “endangered” to “threatened.”
The Florida Everglades is one of the most diverse wetland ecosystems in the United States. These tropical wetlands span an area of more than seven hundred square miles in southern Florida. The term Everglade means river of grass. The system starts in central Florida near Orlando and travels southwest to the tip of Florida. The Everglades has a wet season and a dry season which causes a great change in hydrology. During the wet season the system is a slow moving river that is sixty miles wide and over a hundred miles long. During the dry season water levels drop and some areas will completely dry up. The Everglades has many different aquatic environments all having interdependent ecosystems. The most important factor for all these environments is water. It helps shape the land, vegetation, and all the organism that live in each area. Each environment has particular needs for the organisms living in that area. Throughout the years humans have diverted the water to fit their varying needs. The state has built dikes and levees, dug canals, and have built locks to divert the water. This has all been done to keep areas completely dry for developing and agricultural needs. Today, The Everglades is half the size of its original size. Throughout the years many restoration acts have been created and updated. The Everglades restoration projects have been the most expensive environmental repairs in The United States. This is because The Everglades is one of the three most important wetland areas in the world. The Everglades National Park is the home of thirty six protected species including the West Indian Manatee, the American Crocodile, and the Florida Panther. The Everglades also homes hundreds of species of birds, fish, mammals, and repti...
The Florida Manatee’s popular marine species in the tropical environment of Florida are currently considered an “endangered species”. The ecology (the relationships between living organisms and their interactions with their natural or developed environment), for the manatee (trichechus manatus), requires and is generally restricted to the inland and coastal waters of peninsular Florida during the winter, when they shelter in and/or near warm-water springs, heated industrial effluents, and other warm water sites (as stated in Research Gate (1997) Hartman 1979, Lefebvre et al). The Florida (West Indian) Manatee, An Endangered Species, has no known predators other than humans; in the past, humans hunted
Introduction Caretta caretta, otherwise known as the Loggerhead Sea Turtle, is an oceanic turtle that exist throughout the globe. They are circumtropical species (LeBlanc et al. 2014) meaning they are distributed throughout temperate and tropical ocean regions, but most abundant species are found in the United States coastal range. Loggerheads largest nesting aggregations in the Atlantic are found along the southeastern United States coastal range where about 80% of all nesting occurs and 90% of all hatchlings are produced (Abecassis et al. 2013).
Red tides have made many people sick such as residents and tourists of Florida’s Gulf Coast. The tides also have affected many business owners because many tourists don’t want to come to beach resorts because of Red tides. Red tides are caused by two ways. One of the ways are the algae reproducing and giving an effect of toxic air. Many outbreaks have also occurred because of red tides. Such of these things include poising form fish and shellfish. To stop Red tides, many researchers have done numerous experiments to try to find a way a way to stop Red tides! There are three main solutions to stopping Red tides. If we try to do these solutions red tides will decrease in the amount of times they occur.
Today many people do not see the need to preserve corals reefs. Hence because of the lack of appreciation for the reefs, they are slowly disappearing. Many citizens do not realize the importance of these reefs, the species they hold, and the food webs that connect the ecosystems. Our American government has stated many times that they are doing all they can to preserve and to replenish our coral reefs. However, how accurate is that statement? To answer these questions, we first have to understand what a coral reef is and how it can be saved.
