Marine conservation
From Wikipedia, the free encyclopedia
Coral reefs have a great amount of biodiversity.
Marine conservation, also known as marine resources conservation, is the protection and preservation of ecosystems in oceans and seas. Marine conservation focuses on limiting human-caused damage to marine ecosystems, and on restoring damaged marine ecosystems. Marine conservation also focuses on preserving vulnerable marine species.

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.
Human impact
The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as
When ever you go to the beach, do you ever think about what can happen to an animal and the water when you leave a wrapper in the sand or a plastic bottle in the water? If you think about it, even a small piece of plastic can harm a fish. The fish could mistake it for food. This could potentially kill the fish. There are other things that people d that pollutes the ocean. An oil spill from a boat can get fish sick (Doc.2). Also, solid waste, plastics, glass, and foam (OI). Marine life can get trapped in any of these items (OI). There are many things we can do to prevent this, like, reducing plastic waste in stream, improve solid waste management, and increase, capture, and reuse (Doc.1). These are just a few of the many things we could do to
Coral reefs not only protect coastlines and beaches from wave damage and erosion, but also are the basis for the fishing and tourism industries. Dying reefs is a worldwide problem, and evidence shows that 10% of the entire world’s coral has died, and 60% will die by 2020 if existing conditions continue (NOAA 2000). The reason that the Australian Great Barrier Reef is so important is because not only is it the largest barrier reef in the world, but it is also one of the most evolved models of how to best manage and protect the world’s largest reef system (Ornitz 1996). It extends for 2,340 kilometers (km), covers 345,000 square km and contains 2,900 reefs, 300 coral cays and 600 continental islands (White 1999). Historically, it has been ahead of the rest of the world in terms of recognizing and addressing problems associated with reef degradation.
Coral reefs are generally called the rainforests of the sea, both due to the extensive amount of species they shelter, and to the significant productivity they generate (ICRI 2012). In addition to contributing to a valued habitat, coral reefs provide spawning, nursery, refuge and feeding areas, and provide nearly $30 billion (US) in net benefits in goods and services to world economies, including, tourism, fisheries, and coastal protection (ICRI 2012). Coral reefs are deteriorating all over the world due to untreated sewage and chemical agriculture run-off and unregulated coastal construction, both of which increases sedimentation, but they are also affected by over fishing and destructive fishing practices, scuba diving, and increased tourism (Spalding et al. 2001).
Part 1: The film Chasing Coral was created to serve as a point of awareness to the crisis surrounding coral. Coral bleaching has only recently been an issue, especially since 2014. Coral death, bleaching, and boiling have swept through the tropical oceans, causing the destruction of a keystone habitat that supports 25% of marine life. This film aims to highlight these issues, show their severity, and how they impact these ecosystems. The documentary succeeded in exposing these issues to the world and showing how much destruction is being done in such little time.
Located in tropical ocean waters, coral reefs provide priceless resources to both human and marine life. The leading natural cause of destruction among the coral reefs is global warming. Other natural causes are earthquakes, hurricanes, cyclones, and typhoons. The destruction to the coral reefs from these natural disasters is minimal compared to the dangers caused by man. Man-made destruction has a much wider impact on the health of the coral reefs. This destruction includes over-fishing, damage from anchors, aquarium industry, overgrowth of seaweed, and being smothered by sediments.
Gloria Steinem once said, “Without leaps of imagination, or dreaming, we lose the excitement of possibilities.” Imagination and dreams can make anything possible, including me becoming a marine biologist. Ever since I was five years old, i have dreamed of becoming a marine biologist. My dad, stepmom, and me took a trip to Orlando, Florida and I was terrified of what was to come. I didn't know it had the time, but now I realize that this one experience has shaped me into who I am and what I love.
David Attenborough, a well-known naturalist, introduce us to our modern day “Darwin,” J.E.N. Veron, a former chief scientist whom is the world’s greatest scientific authorities on corals and coral reefs. Veron who has lived and worked on the Great Barrier Reef for most his life has discovered over 20 percent of the known coral species today. And today, he gives us an insight on why the earth’s reefs face a likely mass extinction within the lifespan of the younger generation. During his time as a scientist, he researched particularly on the diversity and evolution of the world’s corals and became aware of their troubles. He then began his studies on the analyses of previous reef extinctions and accrued more evidence of the effects of changing sea levels, temperature stresses, predation by crown of thorns starfish, and human influenced changes in nutrient levels. Veron had witnessed his first patch of coral bleaching off the Great Barrier Reef’s Palm Island in the early 1980s, a tiny clump of white skeleton. Everything started turning white and dies, it was the fast-growing branching corals, but some of the others were horrible to see. After witnessing the mass bleaching, the global damage confirmed a close connection with El Nino weather cycles. By being susceptible to increases in heat and light, corals were alerting scientists to climatic changes. When corals are exposed to temperatures two or three degrees hotter than their evolved maximum, along
The ocean is two-thirds of our planet a vast blue landscape home to many biomes which according to Boyce Thorne-Miller “(ecosystem types) corresponding to sets of environmental conditions that vary with depth, latitude, and longitude” (16). However, the ocean and its biomes is under attack from the changing environment. We can see this through coral reef biomes as they make their home near the shores. Through coral reefs we can view the effects that these changes have on the ocean through how the coral reef biome is affected. Humans are a danger to the coral reefs and the wildlife that resides in the biome. The pollution being released into the environment is poisoning the coral and causes death and malformation to the wildlife. The ocean is changing due to global warming which is causing a change in the temperature and rising water levels leading to a change in the stabile areas coral can survive. The increasing acidification of the ocean is causing the coral reefs to die. I will be looking at the effects these issues cause to coral reefs biomes and the ocean to see the similarities in how they affect both.
“Coral reefs are extremely important for biodiversity, providing a home to over 25% of all marine life. They are also vital for people and business. They provide nurseries for many species of commercially important fish, protection of coastal areas from storm waves, and are a significant attraction for the tourism industry”
Coral reef destruction is a big deal. There are many environmental threats on coral reefs which means they are slowly dying. Coral reefs play a very important part in marine ecosystems. Sea creatures depend on them for protection, camouflage, as a home, and also for food. Scientists believe this could be from natural causes like erosion, and global warming as reasons that coral reefs die off but one of the main reasons is pollution. There are many different ways pollution can affect coral reefs. There is a chemical in sunscreen called oxybenzone that may be contributing to the destruction of coral reefs as swimmers are trying to protect their skin. This chemical has toxic effects on young coral that can damage their DNA,
These three factors, being human impact (pollution/ overfishing), climate change (water temperatures), and natural disasters (hurricanes) play their leading role over the loss of coral reef ecosystems— where reflections such as disease and bio erosion act as the result. The importance over marine biologists, and their conveying message to save the coral reef ecosystem, is a demanding change of our standardized way of life. The science and understanding over this ecosystem can, in good faith, stem a positive human response instead of a negative impact; where through these studies, the public may become aware of the issue and be attentive towards a possible
Responsible for more than one quarter of the ocean’s biodiversity, coral reefs or “rainforest of the sea” not only harbor millions of species but also provide daily nutrients to sustain marine life. Coral reefs prove to be an asset humans by offering food, economic services, and protection. However, coral reefs are experiencing rapid decline in locations which they once thrived due to harmful human activities; these activities is identified by pollution, overfishing or aggressive fishing, and tourism. Bordering coastlines of tropical countries these rocks shield humans by weakening powerful waves during storms. Sturdy but not indestructible they can easily crumple apart in rough weather, but not enough to potentially be fatal. Although laws
Coral reef ecosystems around the globe are threatened by human interferences and climate change. This has led to many scientists conducting studies on global coral reef ecosystems to gain a better understanding of the cause and effects of coral reef damage. In both Hodgson’s (1999) and Carpenter et al.’s (2008) studies, they are aware of the continuous degradation of global coral reef ecosystems. Hodgson's study involved conducting a survey on global coral reef ecosystems to see whether human actions were affecting the health of supposed pristine Coral reefs. Carpenter et al. incorporated Hodgson’s study into a compiled study about the possible extinction of reef building corals due to climate change and anthropogenic effects. Carpenter’s
Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.
In regard to a far less pressing matter, “Tourism is often cited as a motivation for countries to protect their reefs from these various forms of destruction, yet the boom in this industry is also contributing to the degradation of reefs in some areas” (Weber, 1993). The conservation of coral reefs will also lead to the preservation of some of the allure tropical destinations like the Bahamas and Cayman Islands hold, only in part, due to their coral reefs. While the islands, as well as destinations like Australia’s Great Barrier Reef, have a lot to lose from the industry, tourism is also playing a part in the death of the reefs’ coral. From standing on the coral which kills it, to attempting to take some back to one’s house in a suitcase, tourists are playing an active role in the problem for coral reefs. There is also a lot of business in exotic reef fishes and corals to add to fish tanks around the world according to Weber (1993). On top of all this, the desire to maintain the sheer beauty of coral reefs is enough reasoning to protect coral reefs even for those who do not buy into the science behind it. “The first thing that strikes a diver swimming through clear, tropical waters toward the life-laden surface of a coral reef, with its kaleidoscope of sponges, starfish, sea slugs, and myriad schools of colorful, darting fish, is the sheer abundance of living things. Nothing in the sea, and quite possibly on land, rivals coral reefs in biodiversity” says Hinrichsen (1997).
