1. It is a scientific fact that biodiversity is greatest near coral reefs and estuaries. But because of human influence coral reefs around the world are dying. Human coastal development, pollution, ocean warming, and ocean acidification are all things that threaten them. The World Research Institute estimated that about ¾ of the worlds shallow reefs are threatened by climate change, pollution, and overfishing.
Hence, overfishing threatens coastal nations down to the local level, devastating communities whose dominant sources of labor and revenue hinges on healthy, plentiful stocks of fish. Also, marine life imbalance may affect the targeted fishing of top predators such as billfish, sharks and tuna that eventually disturbs marine communities. In fact, it is causing increased abundance of smaller marine animals at the bottom of the food chain. This in turn has impacts on the rest of the marine ecosystem, such as the increased growth of algae and threats to coral reef health. Overfishing is also closely tied to by catch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and
Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely. Thus it is much better to prevent coral bleaching than to accomplish its recovery which may take many
This year, scientists are making extra efforts to teach people about coral reefs and what threatens them. Why are experts concerned? Coral reefs are delicate. Overfishing and pollution can harm them. They can also be affected by changes in water temperature caused by occurrences like global warming.
Not only do they protect us humans from flooding, erosion, and everything else that is bad from the ocean. These coral reefs that you see in pictures and on television, contain the most diverse ecosystem in the planet for the thousands of species that live in them and use them. But just like every vital thing on this planet, they are disappearing and dying off. These damaging activities that we humans do are killing this beautiful, and helpful ecosystem. Coral mining, pollution, overfishing, the digging of canals, etc.
This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold. This allows overfishing to be a problem. Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14).
Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction. The animals hear sonar devices, sound waves from boats, and oil rigs that are really loud. This can cause the animals to have mass strandings, reckless diving, being unable to find food, and have chronic stress. Abigail goes on to inform us that cruise ships have also done a great deal of damage to the ocean life. Since there are poor laws in place regarding the way they dispose of the waste from the ships, it all goes into the ocean untreated with many harmful bacteria, pathogens, and other stuff we dispose of.
Be aware of what you are putting into the ocean and what effect it is going to have on marine life. In conclusion, the amount of oxybenzone going into the ocean is devastating. It bleaches the corals, which then harms marine life, upsets the ecosystem, and effects the economy. Even though we may not realize or appreciate them, coral reefs provide so much to our world. Without them, people would have a difficult time going about their day to day lives and would struggle to get
Travels for colonization was done by boats to travel the sea. The sea can be calm but it is mostly ruthless and dangerous. This is reflected in line 9 and 10 "Listen! You hear the grating roar of pebbles which the weaves draw back and fling". The sea is loud and fights against the pebbles, the fight against humans will be much more treacherous.
Apart from animals getting tangled in debris, it is extremely harmful when there is run down fishing gear, as it results in ‘ghost fishing’. ‘Ghost fishing is hen lost fishing gear continues to catch fish. Larger debris may interfere with the habitat as well. Debris entanglement causes damages the habitat as well like coral reefs and sea grass destruction. Rubbish not only damages the environment but also interferes with it.
It is believed that this increase in nutrients is connected to the increase in crown of thorns starfish population, which poses another threat to the reef by impacting coral cover (Amelia S. Wenger, 2015). Coral diversity, calcification, coral cover and coral development are all being impacted by chemicals reaching the reef (Amelia S. Wenger, 2015). If the amount of chemicals reaching the reef continues to increase, the reef will continue to diminish, coral species will become extinct and reef fish will lose their habitat, forcing them to relocate or
