Have you ever been swimming in an ocean, and you notice a plastic bag or bottle floating in the water? There are many ways people can pollute the oceans. For starters, oil tankers spill oil into the water (Doc 2.). Boats sink (Doc 2), and eventually the boats break up into pieces and spread across the ocean floor (OI). Next, people dump sewage and garbage from boats and on beaches (Doc 2).…
Thus, it is not caused primarily by those activities that take place in the ocean, but of those which are not. According to (Carl J. Sindermann in his book Ocean pollution: effects on living resources and humans) he mentions that as coastal areas continue to expand in terms of people and industry, so does dumping in the ocean. Hence, this waste to the sea comes in many forms such as trash, sewage disposal, toxic chemicals and…
In the hustle and bustle off everyday life, we as human tend to forget just how much man made pollutants we are letting out into the world. Not only do these fumes linger in the air we breathe but also run off into various water sources. Not only are we harming ourselves but also the living things that call the water their home. Some of the biggest pollutants that effect our water systems today are antifreeze from cars, cigarette ash and not to mention pesticides that run off from the fields. We know the effects of these harmful chemical substances can be deadly to humans but how does it alter the lives of the creatures living in the water?…
How to make Mexicali greener city? First, we need to understand, what pollution is. • Pollution is introducing harmful materials into the environment. • These harmful materials are called pollutants.…
The fisheries sector as part of the oceans sector plays a large part in Nova Scotia's economy. The direct GDP impact of the ocean sector in the Nova Scotia economy is estimated at $2.62 billion in 2001, about double the 1996 impact measured at $1.37 billion. This direct impact accounts for about 10% of total Nova Scotia GDP (Gardner, Fraser, Milloy, Frost, 2005). However, it is important to remember for such a large industry, a large amount of waste is produced as well. Currently in Nova Scotia, the majority of fish waste produced from processing plants is being composted.…
This plankton not only feeds the mass majority of the ocean but it also absorbs carbon dioxide from the atmosphere. This absorption takes the harmful gas and stops its circulation much like trees do. In a sense they are key indicators of ecosystem change. For millions of years, the production of harmful and dangerous greenhouses gases was regulated by the natural systems of the planet. John Platt, an American physicist and environmental writer, states that “Carbon dioxide isn't only affecting the atmosphere.…
Everything that was created by the earth was made to be recomposed, recycled and reused. All of these chemicals are now effecting the animals that call the ocean their home. “No breathing species could live on this planet until the surface layer of the ocean was filled with phytoplankton”(page 347). All life on earth depended upon this simplistic organism to evolve and sustain life. Phytoplankton provides food for the fish and most importantly oxygen to breathe.…
The source of marine pollution is plentiful, about eighty percent of them come from land-based activities. Some enter the ocean directly, some pollute ocean indirectly. The first pollutant that enters the ocean directly is Sewage. The used water and polluting substances that are produced by human, flow through river and directly entered the ocean. For example, about 80% of untreated…
Surface water pollution also can come into effect when sewages are filled with trash that later end up in the ocean. Oxygen Depleting pollution is when micro organism including mostly aerobic organisms such as bacteria, fungus and most other plants living in the ocean or other main bodies of water lose oxygen and become more susceptible to catching bad bacteria and loosing the little oxygen they need to survive. When oxygen becomes depleted also known as loss of oxygen the organism growth is more designated to grow and produce more harmful toxins that affect the plants and water quality around them. Some harmful toxins include sulfides and…
There are two main sources of water pollution, categorized as point sources and nonpoint sources. Point source pollution comes from specific locations, such as through a pipe or a ditch. Producers of point sources include factories, sewage treatment plants, and oil tankers. Nonpoint source pollution, on the other hand, cannot be traced to a specific location. Nonpoint sources are more dangerous because they are difficult to contain and research.…
As mentioned earlier, marine animals are victims of marine pollution and toxic waste can be blamed for it. Toxic waste such as oil spills can cause long-term effects on marine life which includes cancer, failure in the reproductive system, behavioural change and death. Oxygen levels in the water are constantly decreasing which is caused by the debris not having the ability to decompose and uses the oceans oxygen as a way to degrade. The result of oxygen levels…
Marine Pollution: Causes There are many observable attributes in which we can classify the various types of marine pollution. Marine Pollution is a major setback and not only hampers the marine species but also is passed on to the land animals as well. Sea water covers around 2/3rd of the planet, which plays an important role in maintaining the essential biological and ecological balance. There has been increasing amount and the various kinds of waste products which originates from expanding technology but with not much knowledge about how these might react with the ecosystem and disrupt our well being. Types of Pollution Observed in Marine Pollution:…
It should be in everyones best interest to minimise the world’s marine pollution, the vast growth of pollution in our ocean is affecting marine life such as coral reefs and sea animals. With pollution on the rise it is declining our marine future, which can be a worry for the worlds oxygen with a large percentage of the planet’s oxygen coming from marine plants. Marine life stability is one of the most important issues this century. We are constantly having large numbers of sea animals dying from various versions of pollution and it needs to be stopped now. If marine life is not looked after properly it could affect humans horrifically in many different ways.…
Pollution is a difficult word to define and one of the greatest problems the world faces today. Many people don’t know where it exactly started. Pollution is considered to be anything that makes the earth dirty and unhealthy. Air, land, and water are agitated by this problem. There are several types of pollution, and they may come from different sources, but all of them generate the same results [1].…
Finally, the last pollution category is pollution of our land. “Land pollution is the destruction of the Earth’s land surface by man because of the misuse of resources” (“Land Pollution” 1). Land pollution is caused by deforestation, erosion, overcrowding of landfills, industrialization, and any type of construction activities. These are all complications with the fact that our population is growing and becoming more industrialized which is leading to the actions of deforestation, which is the cutting down of trees and habitats to build highways, buildings, etc.…
