The Red Snapper is also known as Lutjanus campechanus, they are pink to a red color (Louisiana Fisheries). They are commonly known as the North American Red Snapper, Snapper, Genuine Red Snapper. Their color starts to fade off under their bellies (Louisiana Fisheries). Some key characteristics are their red eyes, and their anal fin pointed than rounded. (Louisiana Fisheries). They can be found in the Gulf of Mexico and the Western Gulf (Louisiana). They can weight about anywhere ranging from 10-50

To quote Christopher Reeves, the actor who plays the role of Superman in the 1978 film Superman, “A hero is an ordinary individual who finds the strength to persevere and endure in spite of overwhelming obstacles.” But what does it truly take to deserve the title of a hero? To be a hero you need to be selfless, have integrity, and be loving. This is why I believe Jesus Christ was such an important hero for not just me, but many people throughout the world. He went through many hardships to save numerous

The movie The Perks of Being a Wallflower, written and directed by Stephen Chbosky, is based in Western Pennsylvania and directed towards teenage boys and girls.

He is trying to cope with the death of a close friend and close relative, his own life, his lack of friends, and starting a new life at a new school. Chbosky does a miraculous job at narrating all of these issues through the eyes

The crown of thorn starfish, Acanthaster planci, are currently responsible for a majority of the coral reef destruction occurring throughout the world. This creature consists of 13-16 arms that allow it to easily latch itself onto its prey. Crown of thorns starfish also contain a venomous spikey exterior that help protect them from predators that may be searching for an easy prey during their four to six-hour feed. These starfish consume coral by extruding its stomach and secretes emulsifying enzymes

responsible to manage Great Barrier Reef Marine Park for the best available scientific information for researchers to conserve the coral reef. GBRMPA responsible to increasing compliance focus to ensure zoning rule are follow, controlling crown-of-thorns starfish outbreaks, monitoring the health of the ecosystem on a Reef-wide scale and implementing Reef Recovery

One of the earth’s most diverse and unique ecosystems, the coral reef, is dwindling due to anthropogenic stressors. Coral reefs across the globe provide habitat to approximately 550,000 to 1.3 million different species of organisms (Wear and Thurber 15). Although reefs can take thousands of years to form, over just the past 27 years, the world’s largest coral reef, The Great Barrier Reef, has seen its coral cover decline by over 50% (Kroon 1987). What is causing such an immense deterioration and

Coral reefs are complex ecosystems which each species having an impact on the ecosystem as a whole. For an example an increase of phytoplankton can lead to an increase of Crown of Thorns starfish because their larvae prey on the plankton. Full grown Crown of Thorns starfish eat soft coral and can have a negative impact on coral populations, and the coral cover of that reef.  There are anthropogenic factors that can lead to an increase in the phytoplankton population, such as nutrient runoff. This

factors, which brings us to the threats with which the Great Barrier Reef has to deal. 5.1 Natural destruction: Crown-of-thorns starfish It seems that every animal in the world acts as a source of food for other animals; this is also true for corals. The crown-of-thorns starfish, which has 21 thorny arms and a length of 80 cm, feeds on corals, coral polyps, and coral algae. These starfish are not commonly found in the waters of the Great Barrier Reef, but some of them reach the area due to ocean currents

Coral Reefs are important to our society because they support bustling diverse ecosystems that provide shelter to a fourth of all identified marine species and act as natural barriers, which protect the coastline from the ocean’s pounding waves. Coral reef ecosystems help to benefit economies by providing protection against erosion, cultivating fisheries, creating and sustaining tourism activities, offering substances for medical uses, and providing a diversity of culture and aesthetics to communities

The coral bleaching phenomenon is occurring all over the world’s coral reefs and it is still happening right knows without we even noticing it. Various approaches have been applied to save this extraordinary God-given structure before it vanishes completely from the earth. However, the world probably should be more concern on the main issues that leads to this problem in the first place. Three major factors that contribute to coral bleaching include the rise in ocean temperature, changes in salinity

runoff over time, is still being investigated (Amelia S. Wenger, 2015). Research has identified that chemical runoff is increasing nutrient levels in the water. 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

Climate change is the biggest long-term threat to the Great Barrier Reef and coral reefs worldwide, according to the Reef 2050 Long-Term Sustainability Plan. It has caused sea temperature increases, ocean acidification, altered weather patterns, and rising sea levels. The sea temperature increases affect many species. It causes coral bleaching to occur, which is when the microscopic algae separates from coral, taking the color, as well as the energy away. It affects the photosynthesis and reproduction

and factories, is then flowed into the sea, harming the coral reefs as well as sea life. Nutrient, increasing, encourage algal blooms that cause a population explosion of devastating crown-of-thorns starfish. Since 1985 coral cover has declined by half, along the Australia Great Barrier Reef, the population of starfish being responsible for 40% of this loss. Tourism also affects the coral reefs, because of people taking away the coral and killing a whole population of polyps. Tourism boats as well

all over the world come to see this amazing site and now they can not because of the terrible catastrophe that laid before. Over the course of these years the reef has been getting much more worse as temperature levels rise as well as the number of starfish. “The health and future of the Great Barrier Reef is a priority for us. Bleaching reinforces the need for us to continue working with our partners to improve the reef’s resilience to give it the best possible chance of dealing with climate change

Why does environmental ethics matter? ‘The essence of an environmental crisis is a cultural and value crisis’ (Zheng, 2012, p. 89). Environmental ethics concern the study of ethical questions that arise in the relationships between humans and the non-human environment (Palmer, McShane, & Sandler, 2014). Whilst many different environmental philosophies exist anthropocentrism is the one most dominant in western culture and has important implications in terms of sustainability (Hens & Susanne, 1998;

cause of coral reef destruction are the invasive sea creatures which destroy or harm the symbiotic relationship between the fishes and other sea creatures that rely on the shelter of a coral reef could provide. One example is the Crown of Thorns Starfish. This starfish is very abrasive in clearing out a bunch of coral reefs. Being spiny and toxic it truly is a superior over small creatures and even if there are some of its predators, these predators are somehow over-harvested for consumption hence
