Humans Need To Change the Way They Think About Coral Reefs

What can be done by humans to take better of the world’s coral reefs? Many people don’t realize that coral reefs are a necessity to support marine life. Currently it is estimated that 10% of the world’s coral reefs have been wiped out and in the Philippines 70% of the coral reefs have been destroyed because of human intervention (Coral Reef Destruction and Conservation). This will be one of humanity’s biggest problems in the near future. By not purchasing certain fish accessories (jewelry) and certain reef fish, reducing the amount of pollution humans cause that increases global warming, stopping deep sea mining and only using organic and ecological fertilizers coral reefs, ecosystems

The fish food trade is currently valued at more than $1 billion dollars (Threat to Coral Reefs: Trade in Coral Organisms). That staggering number seems to still be on the incline, due to it being a very productive and beneficial business. The fact of the matter is, all of this illegal fishing and taking of various species of fish is having a very bad effect on the coral reefs. Methods for capturing these fish such as using cyanide to stun fish for capture, coral mining, and blast fishing, are hurting these coral reefs. Using cyanide as a particular example, is especially bad due to how poisonous it is. Fishermen commonly use this poison to stun the fish they want, but also kill the surrounding fish and corals (Threat to Coral Reefs: Trade in Coral Organisms). When the corals die, it takes a very long time for them to come back, usually around 10,000 years to fully grow back. Corals only grow about 0.5 to 2.0 cm per year ( Coral Reefs). There needs to be a set of laws that are enforced by all the world’s countries to effectively protect coral reef …show more content…
This can result in Eutrophication is where the nutrient load gets to an extent that the community becomes dominated by algal/seaweed, exceeding the capacity to control by grazing organisms (Threats to Coral Reefs-Human Impacts). This disrupts these coral reef ecosystems. With a lack of nutrients there is a side effect of coral reefs not being able to get the nutrients that they need because there is an influx of algae present that take all of the nutrients away. What can be done to reduce this? With the use of organic fertilizers instead of these toxic ones humans use, the coral reef ecosystems can have one less issue that damages these

    Maggie McMahon APES Period 1 October 24, 2014 Coral Reef Ecology Activity (#3) Tourists scenario: Tourists bring business to many of the countries that are surrounded by coral reefs, but the damage they do is putting the future of both tourism and the coral reef in jeopardy. Most people do not realize how fragile the reef is and carelessly destroy it without thinking, as ecologists have discovered patches of dead coral in the shape of diver's footprints. Boat anchors can break off a quarter century of growth in an instant, and if allowed to drag, can leave a trench of dead coral in their wakes. The coral reef and our food web will demolished without any hope of reconstruction if tourists are allowed to continue to destroy it. Tourism's potential…

    Our impacts, starting with pollution, which leads to the emission of greenhouse gases, which leads to irregular climate change and increased temperatures. This has already been the cause of mass coral bleaching and it is only predicted to worsen. Coastal building increases the occurrence of nutrient run-off from construction and chemicals and other toxins. The increased interest in the exotic pet trade damages the coral reefs when trappers usually are careless and will trample or bang on the coral with sticks to get the fish to come out. Over fishing disrupts the balance of this ecosystem and the food chain can be impaired as well.…

    We as humans have over 58% to do with the destruction of the coral reef, and we don’t fully understand the importance of the coral reefs and what they do for the marine life and the ecosystem as a whole. The Great Barrier Reef that was pronounced dead was a complete eye-opener to the whole coral bleaching situation that is occurring all over the world. We as a nation need to come together to educate each other on this issue because although the coral reefs are only 1% of earth’s ecosystems it will have a huge effect on our everyday life. Little by little if we take steps to protecting our reef’s they’ll no longer be in danger and continue to thrive in our…

So if it loses its color that means the worst has happened and the tiny algae are dying off inside of the color making it hard to provide the coral life. The problem has to start somewhere, and we are only ones to be blamed. It is our fault the temperatures of the ocean are rising which cause coral bleaching. Twenty five percent of all marine life lives within the coral reefs.…

    Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…

    They were the first shark species to be put on the U.S. Endangered Species List (Shiffman, July 2014). Because they are highly migratory, it is hard to protect them with U.S. laws alone. Capture of Species These startling statistics may seem like reason alone to ban the capturing of hammerhead sharks, but not every country is equally concerned with the conservation of sharks and endangered species. Some species, such as the smooth dogfish sharks are even exempt from finning laws, as they have a tendency to drive away commercially caught fish, such as herring and mackerel.…

    10% doesn't sound like a great quantity, however it adds up to an immense amount pushing up to 8 million tonnes of rubbish each year dumped in the ocean. These ridiculous statistics are not acceptable and something needs to be done about it, not only for the sea creatures and coral reefs, but for humanity and other land based animals. We cannot live on a planet that has lost 70% of its oxygen because of careless generations of human life not thinking of future era’s health. This is a prime example of people being the biggest threat to this planet. We are selfish and need to stop the nonsense and start taking the ecosystems more seriously.…
