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.
In conclusion, Rick O’Barry and his crew demonstrate prime examples of good global citizens as they raise awareness for the slaughter of dolphins. They were able to change the public’s opinion on hunting dolphins and stop the kids in Taiji from consuming the contaminated dolphin meat. Although Ric broke the law, he did it to save thousands of dolphin lives while he was still active, informed, and purposeful which makes him a good global
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas.
Water pollution has been a growing problem over the last couple of decades. The Pacific Ocean, covering about 46% of the Earth 's water surface, making it larger than all of the Earth 's land area combined, is vastly polluted. This issue is called The Great Pacific Garbage Patch, also known as the Pacific trash vortex, which is a gyre of marine debris in the North Pacific Ocean discovered in 1997 by Capt. C. Moore. The Great Pacific garbage patch formed slowly as a result of the ocean or marine pollution and gathered by oceanic currents.
Ocean Acidification Lab Dyana Padron Chemistry Ms Johnson June 1st 2015 Introduction: Ocean acidification is when the ocean 's pH is downsized. Ever since the industrial revolution, CO2 (carbon dioxide) has increased in the earth 's atmosphere, and much has been absorbed by the oceans, which has made a very large increase in the ocean 's acidity, when carbon dioxide is absorbed into the water, it dissolves forming carbonic acid, which is a factor that take a large part in the acidity raising, because of this, according to National Geography it has been proven that marine animals are having birth defects because of this, and because of the high acidification the acid comes down on the shells (the home) of an animal and dissolves it, causing
Body (30) A. Shark attacks are actually pretty rare for the number of people that enter the water every year. The risk of being attacked by a shark is about 1 in 11.5 million. Although shark population has declined every year, the number of attacks has steadily increased due to the human population growing. 1. With only 152 shark attack fatalities since 1580, you are more likely to be attacked and killed by many other things.
First, excessive household waste contributes to several of the environmental problems that we are facing today. McKibben writes, “More than 46,000 pieces of plastic debris float on each square mile of ocean. ”(334). The decline in the water quality of our oceans is a real epidemic. According to EcoWatch, about one million seabirds and one hundred thousand marine mammals die every year from the plastic debris floating in our oceans.
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
Water is all in all an essential resource on the planet earth. But only 0.3% of the world's total entirety of water can be used as pure drinking water. We need a huge amount of water for drinking every day and also for various other purposes of daily life and for this we take away a huge portion from this 0.3% of pure water.so sea water or ocean water becomes an important source of water. By and large, seawater on the planet's seas has a saltiness of around 3.5%, this means sea water contains dissolved salts of various ions in a huge amount so is unsafe for drinking. Due to this sea water purification has become a major area of concern over the years.
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.
Twenty-four square miles of highly valued wetlands are being lost per year, which roughly equates to a football field going underwater every thirty minutes. Overall, healthier wetlands would have dramatically reduced damage caused by Katrina and Rita because they have the ability to reduce storm surges, loss of life, and property damage. Kerry St Pe puts the importance in this sense wonderfully in her statement, made to the BBC (British Broadcasting Network) in 2005: “We’ve always said that the cost of not restoring this system was far greater than the cost of restoring it... These two hurricanes [Katrina and Rita] proved that we were absolutely
In Mary Kate Frank’s article, “Saving the High Seas” from Junior Scholastic, the author explains how marine life is being threatened by overfishing and plastic debris. Each country controls the water within 230 miles of their shores. After 230 miles, the high seas begin which “belong to everyone.” Only one percent of waters are protected and you can still do many things in protected waters.
Surfman certification is currently only earned through On the Job Training (OJT) at the member’s unit. The PTET states OJT “uses unit specific knowledge and skills to improve an individual’s job performance”. Surfman certification requirements can only be met by driving a boat into breaking waves greater than 8’ under the watchful eye of a certified
Desalination is when sea water has the salt extracted from it, consequently making it drinkable. Desalination seems like a very smart option, the Pacific Ocean is right by California and is the largest body of water in the world. Most of the coast is not suitable for desalination plants to be built because of earthquake factors and other environmental issues such as sea levels rising (another results of climate change). Desalination is a relatively new technology however, and needs improvements to be made before it can become truly sustainable. Desalination is a process that produces over 3.5 billion gallons of fresh water a day.
