How does littering affect marine wildlife?
Littering has become a much bigger problem in the world than it used to be. It has begun to even affect the wildlife around us all, especially marine wildlife. The litter has been getting into the water from many different ways, it can be flushed down the toilet, left on the road and washed into drains and waterways when it rains, and the most common way would be dropped directly into the water by boaters. Plastics have the most affects on the marine wildlife and the plastic makes up over 60% of marine debris. Plastics are also the longest lasting. A plastic bag will last 200 to 400 years, where a plastic bottle takes about 450 years to fully break down. These plastics are not only outliving the marine wildlife but it is also killing them.
In August of 2000 there was a whale found washed up on the shore near Cairns, Australia. When they did an autopsy on the whale to find out why it had washed up onto the shore they found its stomach was tightly packed with different kinds of plastics. Almost 200 square feet of plastic supermarket bags, food packages, bottles, and more was the cause of that whale’s death. Marine animals mistake plastic for food and they eat it, most do not have issues when it comes to eating it, but digesting it is the problem. Food needs to break down before it can be fully digested and these plastics will not break down causing it to fill up more and more until the creature dies.
Turtles are one of the more common marine animals people are aware of that are greatly affected by plastics. When the turtles are babies they will get stuck in the plastic that holds a case of pop together. They will end up entangled in it as a baby and when they start to grow it ends up causing deformities to the turtles shell. The turtle will no longer be able to grow in the area the plastic is but everywhere else it will. But it is not just the turtles that these plastic traps are harming, many animals in and around the sea are dying from them as well. Seagulls and other birds that stay around marine wildlife are getting caught in them as well. They will get their beak stuck shut in them and end up suffocating from it or dying from starvation. Seals have also been known to get caught in them and in the late 1970’s, scientists found that plastic entanglement was killing around 40,000 seals a year which ended up leading to a 4-6% drop in the seal population.
60% of marine debris is plastic products alone. This marine debris is including oil pollution, trash, fishing supplies, anything you could imagine and still 60% is just plastic products. Marine wildlife is struggling greatly due to the amount of plastics that could all be fixed by simply recycling and no longer littering. Whales have been beached, turtles have become entangled and caused deformities, and sea birds have been suffocated.

Why Do People Litter?

...Why do people litter? There are many reasons given as to why this might be. They have all sorts of excuses for littering. They can’t be bothered or are too lazy to find a bin and have no sense of pride in their community. And the worst reason they came out with this statement everybody does it! How many of these reasons or excuses have you heard? Litter is everyone’s problem, and there is never an excuse! According to Longman Dictionary, the word detrimental is causing harm or damage and littering can be defined as the waste of paper, cans, bottles, garbage and even chemicals so as to people have thrown away and left on the ground in a public place. The broadly accepted description of litter is ‘waste in the wrong place caused by human agency’. So who does the littering? Ignorant, lazy, immature, cowards are the list of people who do it in my opinion. Based to a litter statistics I have read in the net stated that most of littering occurs in transport sites, smoking areas and market sites. Chewing gum is a very constant form of litter as it sticks to the footpaths and roads and is very hard, and expensive, to remove it. And the most shocking statement is that men are tend to litter more than women and women usually use bins more than men. Even, our school children are more likely to be the culprit of littering than other people. In my point of view littering is becoming a habit among Malaysian. It has flattering an eye sore to the community and society. Far too often when we...

...Marine aquatic ecosystems are considered to be the largest of the aquatic ecosystems on Earth. They have a high salinity and include bodies of water such as the ocean, lagoon, the deep sea, and sea floors. Once of the marine ecosystems that has been a central focus, especially recently, is the Gulf of Mexico. The Gulf of Mexico is located off of the Atlantic Ocean, and it is considered to have a tropical climate. According to epa.gov, The Gulf of Mexico is the ninth largest body of water in the world. Some of the species or habitants that dwell in the gulf are different types of whales, dolphins, sea turtles, and sea-birds. Along the sea floor there are coral reef situated. There are also large birds The Gulf of Mexico produces a variety of resources that we use. One of the main resources is the fisheries provided in the gulf. Fisheries in the gulf are considered one of the most productive in the world. In 2010, the estimated shellfish and commercial fish harvest from the gulf fisheries was estimated to be about 1.3 billion pounds (epa.gov). Agriculture is definitely affected by the Gulf of Mexico. There is currently an area that is called the dead zone. Within this area of the gulf, there is an excessive supply of nitrogen in this area due to fossil fuel combustion, crop cultivation, and synthetic nitrogen fertilizers. With the increase of nitrogen, there is a process that is called hypoxia that will occur. Many people believe that the species in the fisheries will be...

...As a result, pollution and hence, declining water quality have proved to be one of the main threats to the Great Barrier Reef. More than 90% of the pollution comes from farm water run-off, having been polluted due to overgrazing, fertiliser and pesticide use. Harmful concentrations of these pesticides have been discovered up to 60km into the Great Barrier Reef with a third of the reef now exposed to herbicides. These chemicals wash into rivers and estuaries and flow into coral reefs, harming marine plants and the animals that feed on them. Sediment amounts have quadrupled over the past 150 years causing the resilience of the Great Barrier Reef to worsen, reducing its ability to absorb shocks and recover from...

Plastics in the Ocean

...Plastics in the Oceans We live in an increasing disposable world. Everything from food to electronics ends up in a landfill somewhere. We are always looking for newer and better products to replace what we already have. The consequences of this behavior are resulting in more and larger landfills, toxic water and a myriad of other problems. With our growing population and excessive consumption, the items we use everyday are becoming disposable so the garbage problem continues to expand exponentially. It is a readily accepted fact that plastics has made our lives both easier and safer, but, at the same time, has also left a damaging imprint on our environment and even our health. The waste management industry has done a very clever job of keeping the inner workings of landfill disposal cloaked in secrecy. As a result we give less and less thought to what actually happens to all the trash we throw away every day. Our culture of convenience is so dominant we do not even see the consequences of our actions. Journalist and filmmaker Heather Rogers, in her essay “The Hidden Life of Garbage” takes us on a journey of garbage disposal that most of us never think about once we take the trash to the curb. She explains one particular method that should give us all pause for thought: In new state-of-the-art landfills, the cells that contain the trash are built on top of what is called a “liner.” The liner is a giant underground bladder intended to prevent contamination of groundwater...

Penguins

...The Emperor Penguin and its Endangered Enviroment The emperor penguin is one of the most interesting species of penguin. This flightless animal lives on the Antarctic ice and in the frigid surrounding waters. This bird has a life span of 15-20 years and lives in colonies. Its diet is mainly that of a carnivore. The majority comes from fish. With all the beauty and intriguing life style of this penguin, not all is good. This penguin is in danger. What is causing this danger? It is not any predator in its wild habitat, it’s the effect of human ignorance. Climate change is slowly destroying the ice the penguin lives on. The emperor is on a downward spiral in which extinction is possible at the end of this century. With climate change at a dangerous level, warming may melt sea ice at rates which will decrease its habitat to nothing. With all these dangers there is still more, over fishing by humans is depleting the food source. In this paper I will outline and describe the problems these penguins face. I will also give a brief background on this flightless bird. Emperor is the largest of all penguins—an average bird stands some 45 inches (115 centimeters) tall. Penguins withstand physiological adaptations and cooperative behaviors in order to deal with an incredibly harsh environment, where wind chills can reach -76°F (-60°C)(Van Woert, Michael). They huddle together to escape the wind and reserve the warmth. Individuals take turns moving to the group's protected and relatively...

Summary of Review

...Lecture 3: Arguments against trade * The job argument * Trade with other countries destroys domestic jobs. Economists’ response: * Free trade creates jobs at the same time that it destroys them. * Workers move from the importing industries to those industries in which a country has a comparative advantage. * The transition may impose hardship on some workers initially; in the long term, the country as a whole can enjoy a higher standard of living. * The national security argument * A country should protect industries that are vital for national security. Economists’ response * Protecting key industries may be appropriate when there are legitimate concerns over national security. * However, producers may exaggerate their role in national defence in order to obtain protection from foreign competition at consumers’ expense. * The infant industry argument * New industries need temporary trade restrictions to help them get started. Economists’ response: * To apply protection successfully, the government would need to ‘pick winners’. * If an industry will be profitable in the future, the owners of the firms should be willing to incur temporary losses in order to obtain the eventual profits. * The unfair competition argument * If firms in different countries are subject to different laws and regulations, then it is unfair to expect the firms to compete in the international marketplace...

Ecosystem

...Ecosystem of the Mojave Desert Bio/101 March 5, 2012 Ecosystem of the Mojave Desert The Mojave Desert is 54,000 square miles of its own special brand of diversity; it is one desert - rather than a series of separate entities. By becoming aware of the combined identity, appreciation and better understanding of the issues that affect the Mojave Desert can occur on a holistic level. Generally, at the edges of the Mojave are areas where dominant plant and animal species change from one to another and both, to various degrees may be possibly found on the fringes of the other. The Mojave Desert ecosystem evolves from plants and animals which are resources within each other. Adaption to the rough temperatures and little water, these ecosystems finds many ways to survive. This ecosystem plays host to a wide variety of plants and animals living in an environment that humans may think are harsh conditions. Many animals get their energy by eating plants, but desert plants give up the fruit of their production very reluctantly. Sharp spines, such as a cactus, discourage plant-eaters. The Mule deer avoids these obstacles by eating seeds, although safe to eat, they can be hard to find. Many are small and look like grains of sand. The plant's solar energy flows through the ecosystem as Mule deer, and other herbivores like jackrabbits, fall prey to carnivores like great horned owls, coyotes, bobcats, or snakes (Townsend, Harper & Begon, 2000). Survival in the desert cannot occur...

...land. In 2008, our global plastic consumption worldwide has been estimated at 260 million tons, and, according to a 2012 report by Global Industry Analysts, plastic consumption is to reach 297.5 million tons by 2015. Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power. Our tremendous attraction to plastic, coupled with an undeniable behavioral propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature. Plastic bags are in use by consumers worldwide since the 1960’s, (Mc Kinley, 2010). These bags are sometimes called single-use bags, referring to carrying items from a store to a home. Open bags with carrying handles are used in large numbers worldwide. Stores often provide them as a convenience to shoppers. The number of plastic bags used worldwide has been estimated to be on the order of 1 trillion annually. The use of plastic bags differs dramatically across countries. While the average consumer in China uses only 2 or 3 plastic bags a year, the numbers are much higher in most other...
