The Destruction Of Coral Reefs

Corals build colonies that secrete calcium carbonate to form ocean reefs. When they're healthy, coral reefs provide shelter and food for animals all along the food chain, including the top: us. Across the planet, half a billion people rely, directly and indirectly, on corals for their living. That's why what happens to the 9,000-year-old Great Barrier Reef, as well as to other reefs worldwide, is critical. The floods in Queensland have hurt the Great Barrier Reef by funnelling into the ocean vast plumes of freshwater and agricultural runoff that could severely damage the coral. Besides the extreme rain that sparked the floods, rising ocean temperatures, changes to the ocean's chemistry and the global trade in natural resources — all symptoms of our fossil-fuel economy — are waging a multiform war on the marine

They protect against coastal flooding, wave damage, storm surges, wave damage, and also they provide homes for lots of fish.. Coral reefs are dying because of the increase in ocean acidification that is caused by the increase of CO2 in the atmosphere. Coral reefs may stop growing if the CO2 concentration levels are high which is expected over the coming decades according to the article. Coral reefs are also vital for people and business. In the article it was reported that more than 30 million small-scale fisherman and women depend on coral reefs for their livelihoods, specifically in Indonesia where fish supported by the reefs provide the primary source of protein.

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 fragile structures living within a narrow range of temperature, clarity, salinity and chemistry. Even a slight increase in ocean temperature, or increased CO2… can cause stresses such as bleaching… These stresses slow the rate of growth of the corrals… With some 60 percent of the world’s coral reefs now losing productivity, it’s becoming a global crisis and a scientific mystery."

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.

First, I am going to talk about the importance of coral reefs. Coral reefs are some of the most diverse and valuable ecosystems on Earth. They are home to 4,000 species of fish, 800 species of hard coral, and hundreds of other species. Scientists believe that there are another 1 to 8 million unidentified species (NOAA). According to the National Oceanic and Atmospheric Administration, new drugs are being developed from

    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,

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.

Finally, there are millions of species who live in the coral reef. It is used both for shelter and for a food supply. There is a vast amount of trawlers that come through each year to dredge the ocean. But think about what would happen if the coral reefs disappear. All the species that depend on the reef for shelter would die. And all the species who hunt for food there would also die. Dredging the ocean rips apart the coral reefs wether that was meant to happen or not. If the natural beauty of the reefs and the security it brings to animals dissapeared, it would be a major

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

The key environmental points are that coral reefs provide important ecosystem goods and services for the maritime tropical and subtropical nations. Within the past two centuries, the main drivers of massive acceleration in the decrease of coral reef species that have caused widespread changes in reef ecosystems has been due to the direct and indirect effects of overfishing and pollution during agriculture and land development. Since markets for fish have gone global, along with other natural resources, reduced stocks of herbivorous fish and the nutrients from land-based activities have caused corals to be replaced with fleshy seaweed.

Overfishing, tourism, abnormal fishing methods, pollution are the main causes of human origin that is responsible for the reefs deterioration. For example, the dumping of industrial wastes and waste oil dumping is causing massive harm to the coral reefs, which need fresh water for its

Coral Reefs are distinctive and unique to the areas around them, boasting a variety and biodiversity of species that can rival any terrestrial area. Although the reefs only cover 0.2 percent of the earth's oceanic floor, an estimated one million species found around coral reefs (NASA)—around 25% of our marine species (Coral Reef Alliance). Beyond science, reefs generate an estimated $375 billion each year (Bunting). Coral reefs benefit the aquarium, fishing, and ecotourism industries, creating at least 500 million jobs (Chasing Coral).

Coral reefs are indispensable to multiple life forms, particularly human beings. In response to concerns, many environmental

The deterioration of coral reefs is mainly linked to human activities – 88% of coral reefs are threatened through various reasons as
