The Cultural Effects of Coral Bleaching Located in warm, shallow waters, one species is near it’s extinction. Scientific studies has anticipated this for years, but many people do not understand the _damage this obsolescence would have on the environment. An essential animal in the ocean, coral, is, “home to 25% of all marine fish species,” according to The Reef Resilience Network, which specializes in helping save coral. Corals have very special tolerances to things like temperatures, salinity levels, and pollution, which causes coral stress, or bleaching. When bleaching occurs because of the unsuitable conditions, the corals expel the algae living in them, turns white, and dies, When corals die, thousands of sea creatures living around reefs
This year, scientists are making extra efforts to teach people about coral reefs and what threatens them. Why are experts concerned? Coral reefs are delicate. Overfishing and pollution can harm them. They can also be affected by changes in water temperature caused by occurrences like global warming.
In November, Hurricane Mitch, blew in and tore away part of the reef leaving behind some corals, known as the “standing dead”. After that, El Niño came along and brought warmer water than usual which parched the reef to death. This led to coral bleaching and a 48% decline in coral cover. Introduction Coral reefs are an island’s protective mechanism, and are one of the most diversified ecosystems in the aquatic system. Its richness is comparable to tropical
1. 90-100 million tons are killed and wiped off the planet each year. Consisting of some of the most beautiful creatures on the planet. Fish are a primary food source to 3.5 billion people worldwide and the depletion of the species is leaving millions of people hungry. Over fishing is a huge problem that needs to be stopped.
Compared to many other species of water animals the sea otter is pretty new to a marine existence. The biggest threat to sea otters is oil spills. They are very vulnerable because they rely on their fur to keep warm. When their fur is soaked with oil, it loses its ability to retain air so the animals can die quickly from hypothermia. The liver, kidneys, and lungs of sea otters also become damaged after they inhale oil or ingest
In the eighteenth century the Black Death just ceased and stopped killing as many people as before, but nobody knows why. It soon found its way all over the world. The production of vaccines cut the death rate by a big chunk. Presently, there are only 200 deaths yearly, due to bad sanitation, mainly in Africa. V. It can take a long time to create a vaccine, taking mostly around ten to fifteen years, involving multiple tests.
Another thing that effects the blue crab 's ecosystem is its environmental threats. To begin, one of the environmental threats that blue crabs face is pollution. In the text, it states, “Approximately 6.4 million tons of plastic and other debris enter the oceans each year. And every year., more than 1 million marine animals die from eating or getting caught in this debris,” (Dignan 13). This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem.
When the water of the sea becomes warmer due to higher temperatures which diminishes the oxygen content, the coral expels the algae that exists within their tissues causing it to turn completely white. This results in coral bleaching. Thus, the elevating heat stress which results from high sea temperatures serves as the main factor that induced damage to the coral reefs. If the heat prevails, the reef may even die instead of recovering. Coral reefs provide home to a significant number of sea species and coral bleaching causes their habitats to destroy completely and effect the marine life adversely.
That’s about 564,000 deaths annually and 1,500 deaths per day. With that shocking statistic comes the thought of losing to this terrible disease that you’ve let define you for so long. That’s what Brittany Maynard thought until she came across the Death
Coral bleaching is when the animals that build the coral shed the algae that give them their color and is necessary for survival. Coral bleaching is suspected to happen by two different ways. The first is due to warmer water. The coral needs to be in certain temperature in order to maintain its life. The second way is due to pollution.
Over the past century or so, twenty-two of the fifty states have lost an average of fifty percent of their wetlands, however, Louisiana’s total loss is over ninety percent of the nation’s total. What is somewhat different about Louisiana’s land loss is that it is natural. The land it was built on is naturally inclined to sink over the years. The real problem with this in the last century, is that land is now being lost far faster than it can be replaced. This loss ranges from 0.1 to 11.1 square miles, depending on the place.
If the Salton Sea starts to dry up severely both wildlife and humans will be affected. The more it dries up, the more toxins are sent into the air. Residents that live near the Sea and even people that live very far away will inhale these toxins that can potentially cause cancer. Deaths have already occurred as a result of this and many more are bound to happen. The Salton Sea serves as an important stop for migrant birds.
Another natural cause is oceans and hurricanes. Both the ocean waves and hurricanes accelerate erosion, which is a main cause to the marshes disappearing. Something New Yorkers should realize is that "80% of oil and natural gases produced in the U.S. travels through our marshes" as according to page 12. America 's economy could go so wrong if the marshes the oil processes through suddenly disappears. Also, a huge percentage of marine life loves in Louisiana 's marshes.
Furthermore, Hurricane Katrina effected over a million people, thousands remained displaced a month after the storm passed, since the body count outweighed the number of shelters. Prior to landfall, the doors to the Superdome opened and approximately 16,000 people sought refuge there, but 16,000 would not even make a dent in 70,000 people who sought shelter after the storm. After Katrina took her path through the south (dissipating near the Great Lakes), the damage continued. As the shelters arose, FEMA officials became aware with that fact that their accommodations would not be enough. “More than one million people in the Gulf region were displaced by the storm.
