Sylvia Earle's Sea Change: A Message Of The Oceans

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

“Our past,our present and whatever remains of our future,absolutely depends on what we do now”.Sylvia Earle did was one of the best oceanographer scientist not only did she explore it she also protected it also tried to raise awareness.Today i'm going to be writing a report on Sylvia Earle a famous scientist that study the oceanographer area of science.What i’m going to include in this report is her early life,what she’s known for,how she changed the world and why I might want to do this job.

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

For the past 5 years I have worked with NOAA at the marine protected areas center both on the MPA inventory and as ocean use mapping coordinator with Mimi D'Iorio and Charlie Wahle, whom I believe you know from your days on the federal advisory council. The ocean use work is dependent on building an effective network of partners that range from state and federal agencies to ocean stakeholders including non-consumptive users, commercial and recreational fishermen, and conservationists. Through my work with the Pacific Regional Ocean Uses Atlas I have demonstrated the ability to build such a network that leverages capacity of state and local partners, and engages the ocean community to participate in a process that assists in the development of federal ocean and coastal policy initiatives.

A few year ago, California began the process of establishing a system of MPAs along the north central coast as a part of a statewide marine protected area system as a result of The Marine Life Protection Act (MLPA), state legislation passed in 1999, that directs the state to redesign its system of MPAs to increase cohesion and effectiveness of the network, improve ecosystem protection in state waters, and improve recreational, educational and study opportunities provided by marine ecosystems subject to minimal human disturbance (Gleason et al. 2010)

In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.

In comparison of David Allan’s masterfully sculpted Overfishing of Inland Waters to Myers’ vastly informative Rapid Worldwide Depletion of Predatory Fish Communities, the two contrasting writing styles embodied in the journal entries are blazingly evident. While each article shares the same postulation of mankind milking our oceans dry, the similarities stop there. One presents itself in circuitous manner and the other undeviating, not slowed by the baggage of excess verbiage. Regardless of the authors’ approach, each article contains largely similar evidence. The importance lies within the information: not presentation.

Only 100 miles off the coast of the Gulf of Mexico, there is a marine ecosystem teeming with life. This ecosystem is called the Flower Garden Banks National Marine Sanctuary (FGBNMS). FGBNMS is a coral reef that monitored and preserved by NOAA, the National Oceanic and Atmospheric Administration. NOAA sees the FGBNMS as a valuable natural resource that we need to protect. The intent of this memo is to identify the resources that FGBNMS provides, what policies are in place to protect those resources, what effect these policies have had, and what actions to take from this point forward. Fortunately, the policies regarding this natural resource are accomplishing the goal of protecting this reef, so I do not recommend to many changes to the existing policies, except for a few slight changes.

95% of the ocean has not been explored. With all the species and environments within the ocean that we have discovered, it is mind blowing to think that we have only seen 5% of what the ocean has to offer. The World is Blue: How Our Fate and the Ocean’s are One explores our long standing relationship with the ocean. This book is penned by oceanographer, explorer, and lecturer, Sylvia Earle. She earned her B.S degree from Florida State University, M.S and PhD from Duke University, and has accumulated 22 honorary degrees. She has worked as a director for multiple corporate and nonprofit organizations and as chief scientist for the National Oceanic and Atmospheric Administration [1]. Earle’s research concerns marine ecosystems with an emphasis on conservation, which is the focal point of her novel. It is woven with stories compiled from decades of work and exploration, and with facts and arguments concerning our changing ocean. Sylvia’s novel is about the relationship between humans and the ocean, whether it be through the extinction of species, climate change, or even exploration and aquaculture, we ultimately affect the ocean and it affects us.

Our plan of the United States Department of Interior banning all commercial fishing in Marine Protected Areas,and establishing and enforcing regulations for the recreational use of these areas fits to the resolved. The program will be run directly from the government as said from the plan. Our plan will be saving our nation approximately $250 million of discarded fish. The amount of fish we have wasted is breaking down. This plan will help to restore our marine ecosystems so we are able to have another millennia of fish to eat. Our plan also will promote the development of the Earth’s oceans. According to Ocean Conservancy, “Underwater parks, called marine protected areas...allow fish to grow larger, stay healthier, and reach greater abundance and diversity. Fish thrive in these areas...move to other parts of the ocean and replenish weaker populations...We people depend on healthy fish for survival...Underwater parks hold up even in the face of disaster.” our plan of increasing these marine protected areas are crucial if we want to continue to live off of fish meat. Also, Callum Roberts says that Marine protected Areas can “allow recovery of species such as corals, sponges, sea squirts, and mollusks that create complex bottom structures that blind the seabed and perform countless other vital roles such as filtering the water.” the plan of expanding marine protected areas will greatly develop the ocean and its

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

However, many fisherman are unable to catch as many fish as they used to, so they are increasingly using cyanide and dynamite in fishing, which further degrades the coral reef ecosystem.[6] This perpetuation of bad habits simply leads to the further decline of coral reefs and therefore perpetuating the problem. One solution to stopping this cycle is to educate the local community about why conservation of marine spaces that include coral reefs is important.[7] Once the local communities understand the personal stakes at risk then they will actually fight to preserve the reefs. Conserving coral reefs has many economic, social, and ecological benefits, not only for the people who live on these islands, but for people throughout the world as well.

Seagrasses are essential primary producers that provide habitat and refuge to fauna. Anthropogenic influences have caused global loss of seagrasses and a major contributor is eutrophication, which increases phytoplankton and algal populations, reduces light availability, and causes daily hypoxic conditions. Eutrophication is commonly linked to declines in temperate conditions and is more difficult to link to tropical systems since decreases are typically related to physical damage and diminishing light conditions from runoff. Climate change, herbivore declines, disease and overfishing, along with anthropogenic impacts from coastal development, run-off, eutrophication, and aquaculture have caused declines in coral reefs and mangrove systems. These three systems are interconnected and when one system is impacted, secondary impacts are observed in the other systems; coastal ecosystems will be adversely effected and decline. Additional research, conservation, and ways to reduce anthropogenic impacts have been discussed. Restoration is used to reverse habitat loss, although success is varied. Coastal systems and the biological and ecosystem services they provide, may take decades to establish. Marine Protected Areas (MPAs) are instituted to protect systems from further degradation, restore communities and allow them to flourish naturally. However, local residents are affected by MPAs and may become displaced, have restriction placed on their livelihood, or elimination of their
