Coral Reef Informative Speech

Good Essays
Good day ladies and gentlemen. My name is Crystal. I would like to inform you about some of the threats to our beautiful coral reefs.

Imagine that you were doing some deep sea diving and you happen to swim along this beautiful, interesting and colorful wave of wonder made of stony corals and consist of plants, fish, clear waters, and many other creatures. Coral reefs have often been referred to as the rainforests of the ocean and they are one of the greatest wonders of the ocean.

Coral reefs are underwater ecosystems that are components of a larger ecosystem. Reefs represent one of the most diverse ecosystems in the world. The animals that live on or around the reefs depend on it for food and shelter. There are countless of dangers that threaten coral reefs. Coral reefs have survived thousands of decades of natural change, but many of them may not

Pollution from humans are killing coral reefs around the world. Sewage and oil pollution are a few of the pollutions that are poisoning and killing coral reefs. “The net effect of pollution is as bad or maybe worse than the effects of global warming,” said Iglesias, a co-author of the study in the journal Science on how climate change affects reefs (Pollution Killing World's Coral Reefs). Sewage pollution of coral reefs have been recognized as a major environmental problem for many years. Levels of sewage pollution are very high and has caused a variety of sponges, and other species to decline. Releasing sewage into the ecosystems is one of the primary causes of coral reef degradation. Coral reefs ecosystems are extremely sensitive to environmental disturbances. Longer exposure and higher concentrations of oil is killing corals. “Death may not be immediate, but rather take place long after the exposure has ended”(How does an oil spill affect coral reefs, n.d.). Damage to coral reefs are making them collapse. Concern for damaging effects of oil pollution is currently a growing

    The symbiotic relationship between algae and coral is at risk, if the temperature is even off by a few degrees, whole ecosystems would collapse. The algae live on the coral, feeding it with the byproducts it uses, the specific temperature requirement for the chemical process and enzymes is very delicate. The Great Barrier Reef demonstrates the effect of the acidification and ocean heating. The ocean ph is dropping rapidly, reducing its ability to regenerate and house organism, which already endemic only to the reefs. The temperature is hotter than ever with evidence with the Authorities of the Great Barrier Reef stating, "Analysis of coral cores in centuries-old corals suggests that current temperatures are warmer now than over the last three centuries.…

    Not only does direct contact with oil destroy the coral, but also even with clean up attempts, large traces of oil can still be found. As a result, any habitats damaged by oil do not fully recover, if at all. ("Coral Reefs and Oil Spills"). All of these factors combine to eradicate entire ecosystems (Oceana). Therefore, the immense quantity of oil released from offshore oil drilling poses a large risk to the wildlife and their valuable habitats.…

    Octopuses, squid, clams and marine snails are often spotted near coral reefs. These reefs face danger in three different ways. One, they are affected by chemical waste in the ocean, which is disposed from industries, and agriculture. What happened is that industries produce a runoff, and it is disposed in the ocean, which is environmentally unhealthy and it damages a lot of life in the oceans. Not only does industries have a negative effect on coral reefs, but so can boats and ships.…

    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.…

    Ocean acidification is described by many scientists as a consequence of rapid increase of carbon dioxide absorbed into the ocean. As ocean acidity increases, its capacity to absorb CO2 from the atmosphere decreases. This decreases the ocean 's role in moderating climate change, "they write (Cullinane.1). As serious as this may seem several damaging effects are happening to the oceans as we speak. The most important creatures in the ocean’s ecosystem like coral are being depleted and overpopulation of photosynthetic algae is going overrun the oceans if nothings done.…

    They are also being battered by waves and storms, like the one that created One Tree. Thus, just to hold their own, reefs must always be growing” (“The Sixth Extinction”, Kolbert). Ocean acidification kills coral reefs, as Elizabeth tells us on this chapter: “One Tree’s reef flat was brittle and brownish… it crackled ominously underfoot” (“The Sixth Extinction”, Kolbert). With the death of Coral reefs comes the death of all life on it. This CO2 that is causing the ocean to acidify has been caused by us since hundreds of year.…

    Much of the plastic accumulates on the ocean 's floor, as well as chemicals like lead and mercury killing the organisms that come into contact with them. Secondly, many fisheries exploit deep sea resources due to the lack of them on land and in shallow waters. Although the climate change may play the biggest factor in years to come. Increased water temperature could devastate this ecosystem so badly due to the adaptations they have acquired to become so accustomed to what it is now, which inevitable will kill them. All these negative impacts could cause the loss of so many organisms and resources, many of which that have yet to be discovered, leaving them to be an opportunity missed or a mystery unsolved forever.…

    Bleaching is caused by the loss of the zooxanthellae, the tissue that lives in the corals. Without it the coral grows weak and it is harder to fight the diseases. These diseases can be caused naturally or be stemmed from the factories that pollute the ocean (Science 20). The cases of bleaching were relatively small, but the recent years have shown a high rise with the related matter. The rises of bleaching is the death of an ecosystem.…

    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…
