Great Barrier Reef Threats

Petrol released by boats 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 damage the coastal reef by crushing and destroying it when

Pernambuco is the most deadliest

THE IMPACT OF HURRICAN IRMA ON THE UNITED STATES ECONOMY INCLUDING TO THE VIRGIN ISLAND Monica Providence Mgt 213 Midterm Exam Dr. Professor Paul Flemming University of the Virgin Islands November 30th, 2017 THE IMPACT OF HURRICANE IRMA ON THE UNITED STATES OF AMERICA INCLUDING THE US VIRGIN ISLANDS Hurricane is one of the most damaging natural disaster. They are terrifying to the occupants in its part as well as on the economy. The United States including its territories are vulnerable to hurricane damage, because one-third of its gross domestic product is from states along the Gulf and Atlantic Coastline (US Economy). Hurricane Irma with such magnitude of a category 5 hurricane creates a vast effect on the economy of

About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.

Lars Gustafson 11/4/15 GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet. According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly. Sharks rely on their fins to swim and allow water to

The Hurricane in 1928 was the second deadliest hurricane in US history, causing massive flooding from the storm surge of Lake Okeechobee with over 2,400 deaths. They did not want this to happen again so congress authorized the US Army Corps of Engineers to build the Herbert Hoover Dike. In 1947 another set of Hurricane’s came through and flooded Florida sparking Congress to act. Congress made the central and southern Florida

Cane toads are an invasive species in Australia with a range of significant impacts on the Australian environment. They were introduced to Australia from Hawaii during 1935, and their population has since grown to approximately 200million, despite multiple attempts at controlling the growth. They primarily inhabit Queensland, New South Wales and Northern Territory. Adult cane toads are usually heavy-built and weigh an average of 1.8kg, with warty skin (wikipedia.org, 2015). They pose a risk to many large predators that are poisoned when they try to eat their highly toxic bodies (Shine, 2014).

In 2010, there was a catastrophe of Oil Spill in Mexico and it bigly affected individuals ' lives and species in the ocean. A seaward British BP Oil rig broke and spilled around 30,000, 40,000, and 60,000 barrels a day for more than 2 months. This was a catastrophe for nature and for a huge number of individuals. The occurrence that happened on April, 2010 has put a major effect on individuals ' lives. The affliction of Oil Spill in Gulf of Mexico was in the middle of life and passing on the grounds that the conductor did not check for wellbeing first.

Coastal winds boosted this giant mass of destruction , and many tried to escape but not many could . These wind speeds could devour anything in its course. Obliterating many houses and buildings it would prove to be one of the deadliest , costliest , and biggest hurricanes that ever formed. ("10 Hurricane Andrew Facts") Impacts on America were very harsh living conditions ,electricity down , and wounded and injured. Medical Conditions and help were on the way.

Overfishing is serious problem in the world today, more than half of the world’s population depends on the oceans for their primary source of food. Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing.

The tsunami hit many countries after an earthquake that happened 93 miles off the coast of Sumatra. Although Hawaii had the technology to warn the countries but it was too late and the tsunami hit. The tsunami took almost 300,000 people 's lives. People were devastated when they heard of the tsunami, but they became even more saddened when they heard of Hurricane Katrina. Hurricane Katrina was formed around the Bahamas on August 23, 2005.

Discussions and Findings What impact are chemicals currently having on Corals and fish species on the Great Barrier Reef? The impacts of chemicals on the Great Barrier Reef are far beyond what is first expected. The reef is subject to effects of sediment, nutrients and chemical pollutants that currently effect 25% of the worlds coral reefs (Amelia S. Wenger, 2015), including the Great Barrier Reef. These three effects result in a decline in water quality, which is due to an increase in nutrients caused by fertilisers, herbicides, insecticides and sewage. This particular cause for water quality results in the increase and spread of algae and other organisms that compete with coral (Amelia S. Wenger, 2015).
