2. Impacts of Tourism on Environmental Attributes of Small Islands Environmental attributes which are related to tourism in the islands include coral reefs, beach, water, vegetation, wildlife and fisheries (Farid et al, 2013; Uyarra et al, 2005; Teh and Cabanban, 2007). Coral reefs are one of the attributes that has received critical attention as facing visible effects of tourism activities (Briassoulis, 2002; Hall; 2001; Gladstone et al, 2012 Needham, 2008; Nuva R et al, 2009). Tourism activities are able to affect coral reefs either directly or indirectly (Reopanichkul, 2009). Direct effect implies to the intrusion to the coral community through accidental disturbance.
One problem is El Niño, which makes the water hotter than the corals are used to, and hot, still water for long periods of time creates heat stress the corals cannot survive with (Howard). When the water is too warm for the coral’s main food source, algae, it becomes toxic to the coral, resulting in the coral extracting it. When this happens, it gets rid of all color from the coral tissue, leaving behind a transparent skeleton. This process is called bleaching. If the coral goes too long without the algae, it will basically starve itself to death.
This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold. This allows overfishing to be a problem. Not to mention, another environmental threat that this fascinating animal, the blue crab, faces is climate change. Corresponding with the text, “Climate change is another major threat to life in the oceans. Warming ocean waters, rising sea levels, and violent storms disrupt the lives of many species and affect fragile marine ecosystems,” (Digan 14).
Castello Argonese, a tiny island in the Tyrrhenian Sea gives us an enlightening glimpse of Earth in 2100. Chapter six of the book The Sixth Extinction by Elizabeth Kolbert, is solely devoted to her experience in these waters where the vents on the sea floor bubbled up almost 100% carbon dioxide. She talks about the consequences of constantly burning fossil fuels to add about 365 billion metric tons of carbon into the atmosphere and how it could lead to our own demise. The thing about carbon dioxide is that the moment it interacts with water, it becomes an acid which can be deadly to the animals living in these oceans obviously, but also to organisms above sea which includes humans. Elizabeth Kolbert wants us to understand that our actions have tragic consequences and we too will be part of that tragedy if we don’t stop now.
This is unsafe for one reason, which is toxins. The scientific name is known as Paralytic Shellfish Poisoning or (PSP). Starting off, paralytic shellfish poisoning is a silent killer. Paralytic poisoning is an illness caused from eating shellfish that have been exposed to dinoflagellate algae ("Paralytic Shellfish" 2 . This is a natural occurring toxin, that is caused by some types of microscopic algae.
And how we use our vote to to tell our leaders that we know the truth about climate change”, says Leonardo Dicaprio. In the Documentary Before the Flood, Leonardo Dicaprio travels around the world to meet with scientists, activists, and world leaders who inform us about climate change and how it affects our environment. Rhetorical devices are used throughout the documentary such as pathos, logos, and ethos which all are effective and help make claims that are efficiently supported and understood. The rhetorical device of ethos is widely supported throughout the documentary due to the use of scientists, politicians, government companies, and activists who all have credibility and a title that is highly looked up to. Gregory Mankiw is a professor at Harvard and teaches economics.
In this article, Moral hero and Nazi which are the two contrary terms is used to describe Singer. Singer is represented as a moral hero as he is the father of the modern animal rights movement. Singer is an influential philosopher where his best- selling book ‘Animal Liberation’ helped him to be one of the world’s 100 most influential people on TIME Magazine’s 2005. His great job leads to huge improvement in the treatment of animals. On the other hand, the description of Singer as the ‘Nazi’ is being applied because in a 2012 op-ed defending abortion, Singer claimed that “membership of the species Homo sapiens is not enough to confer a right to life.” He also mentioned that "Killing a disabled infant is not morally equivalent to killing a person.
Terry Fox transformed the face of cancer with his big dreams and bigger actions. His long, hard road to success was the type of encouragement people need to help with the fight against cancer. Although he knew that cancer will forever change his life, he took that and made it into a positive. He could have immersed himself in self pity but instead, like a true iconic man, he fought for what he
“The land itself -- should be as dear to us all as our political heritage and our treasured way of life. Its preservation and the wise conservation of its renewable resources concerns every man, woman and child whose possession it is” (“Disney Celebrates”). A global issue today is climate change and sustainability. Many corporate companies have begun to change their environmental practices in order to combat greenhouse gas emissions. One such company is the Walt Disney Company.
The Japanese Sea lion in the 70s, and The Baiji Chinese River Dolphin in 2006 have been victim to our careless actions. Let’s not make sharks the next. World leaders, I am not here to just tell you about the demise of sharks, but to ask you to take action to halt their demise because this problem is on all our hands. As we speak ships are carrying fins to destinations across the world to your country. Currently, there is no international law to prohibit the selling of shark fins.
Levees direct river water straight into the Gulf of Mexico, where it no longer deposits sediment along the coast (p. 36). This causes all the excess water into only one location, and create pressure into one area to cause the levee to break. This happened in 1973, where the dam almost broke. People don 't realize that little things like that are actually affecting many things all at once. Something else people don 't realize, is that people are also the reasons to why the marshes are vanishing.
We are now in the middle of the sea and cannot see Isla Tiburon or Kino behind us at 8:45am. We spotted about 150 grebes at 8:41am and saw more greebes at 8:45am. The sun tried to come out at 8:50am. Then we finally got out of the fog and started to get our bearings. On our left was Isla Tiburon and on our right was Isla Cholludo.Yesterday Ami had a class on fish identification,
Phosphorus and nitrogen feed algae blooms that block sunlight to the underwater bay grass and leaving a low supply of oxygen in the water. All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick.
In Mcewen’s article river restoration project offers a sprinkling of hope” he states that “san joaquin... has temperatures more suited for bass and bluegill. So thanks to the choice of fish, the project will result in failure thanks to the salmon when it could have succeeded with bass or bluegill. Due to the poor thought on the matter the government
This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish. The shellfish, mostly oysters, therefore try to grow in water that is too acidic.
