When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.
Keeping the pollution to a minimal isn’t the easiest thing in the world to do. The major water pollutants are chemical, biological, or physical materials that degrade water quality. Pollutants can be classed in to eight categories, each of which presents its own set of hazards.
Petroleum products are one of the most toxic substances to the ecosystem. Oil and chemicals derived from oil get into the water mainly by means of accidental spills from ships, tanker trucks, pipelines, and leaky underground storage tanks. Many petroleum products are poisonous if ingested by animals, and spilled oil damages the feathers of birds or the fur of animals, often causing death.
Pesticides and herbicides are toxins that are used to kill of unwanted animals and plants. These may be collected by rainwater runoff and carried into steams, rivers, lakes, and e...
The Everglades used to be a very beautiful tourist attraction, but have been largely affected by the existence of pesticides. However, the majority of pesticides is not specifically targeting the pest only but they also affect non-target plants and animals during their application. The Effect of pesticide runoffs on the Everglades is destroying one Florida’s major tourist attractions due to the cultivation of sugar cane just to mention one of those responsible and creates a loss of natural habitat, water pollution, and threatens existence of wildlife. Many pesticides are not easily degradable; they persist in soil, leach to groundwater and surface water and contaminate wide environment.

Water pollution is a very serious problem as it affects one of the most essential ingredients to our very livelihood. The earth is covered in water, in fact about 70% of the Earth is covered in water, only
'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling
The book starts with a foreword that highlights the motivation for having written the book. The book has a table of contents organized into seventeen chapters that highlight the different effect of the use of pesticides to the ecological system within the earth surface. The book is chronologically organized into chapters that flow and express a single idea for the writer. This organization has given the book much readability regarding the flow in its content and format to a
As swans drift with the current on a secluded lake in upper Canada they think not of the water they are in but of dreams of the past and wants for the future. On the other hand, seals off the coast of Northern California fear for their lives every day of humans exploiting their natural habitat. Many things can endanger water born animals, and most all of these come directly from humans. The pollutants of water come from many sources both close and far away from the water body itself. Wastes of humans are the major cause of pollution in the water, such materials include sewage, chemicals among other notable items. First, the composition water: water is odorless, tasteless and a transparent liquid. Though in large quantities water appears to have a bluish tint, it maintains the transparent tendency when observed in smaller quantities. Water covers approximately seventy percent of the Earth's surface in the solid and liquid form. Pollutants can be carried over a great distance by combining with evaporating moisture, forming clouds and then the wind taking the clouds to the larger body of water. This process is called acid rain and it is a major source of water pollution. Acid rain has been a problem since the Industrial Revolution, and has kept growing ever since. With acid rain moving over to a fresh water body, the plants and animals could experience pollution that they never had to deal with before and they could possibly die for the sudden change without them having time to adapt, if this is possible.

This is shown in the first stanza of the poem, in the first and second line “ Because I could not stop for death- he kindly stopped for me.”(Dickinson 670) The suggestion of the “ immorality” in the line four shows that there is life after death. This poem recommends that death is less painful and much more pleasurable than painful or uninteresting. To her, death seems as charming to endless time. The third stanza shows that how she looked back on her life, as she is passing away. ” We passed the Fields of Gazing Grain- we passed the setting sun.” (Dickinson 670) This stanza shows that if there is no life after death it wouldn’t have the ability to look back on her life. “ The dews drew quirening and chill”(Dickinson 670) this is when we understand that she is dead in
Emily Dickinson’s ‘Because I could not stop for Death’ addresses one of the most mysterious aspects of life - death, and what comes after it. She describes and personifies the character of Death, and explores the concept and possibility of immortality and she journeys in a carriage towards her own impending death. As the poem continues, her understand and maturity towards death deepens as she gets closer to Death. Dickinson lead a secluded life overshadowed by the frequent deaths of her relatives, which was reflected in her poetry. The poem’s tone is calm and accepting of death - she does not try to delay or avoid death. The poem is written in Emily Dickinson’s signature fragmented style, full of enjambment and caesura cleverly placed to create tension and emphasis for effect. The poem’s unpredictable structure and rhythm makes each stanza unique and gives the poem an overall uneven beat, mirroring the horses that pull her carriage. The first stanza is written in common meter, a structure commonly used in hymns, hinting at Dickinson’s religious background. ‘Because I could not stop for Death’ challenges our view and ideas of death as Dickinson recounts to the reader her journey through life to whatever lies beyond.

Emily Dickinson is said to be one of America’s greatest original poets of all time, because she experimented with literary elements in order to free them from their standard restraints. Dickinson shaped and molded a new type of persona for the first person point of view. Although, the first stanza begins with a relaxed and pleasant tone, nothing appears relaxed, pleasant or cheerful throughout the rest of “Because I could not stop for Death”. Instead, the narrator’s journey with death demonstrates that Death will not wait for you, It always comes no matter if you are prepared or unprepared.
In Emily Dickinson’s poem “Because I Could not Stop for Death” she uses a variety of poetic devices to enhance the feeling in the poem. In the poem, Dickinson writes, “ The Carriage held but ourselves/ And Immortality.” (3-4) she is using personification when giving immortality human qualities as he is supposedly riding in the carriage along with her and death. Alliteration is also a poetic device that is used in the poem when, “We passed the setting sun” (Dickinson 12). The most interesting device that is used in the writing is a very extensive extended metaphor comparing death to a journey. Emily Dickinson uses very good word choice throughout the poem making the carriage ride of death and the passing
At first, she explained that she could not make herself to available for death, so death had to present himself to her, in a carriage nonetheless. She was so unbelievably busy with her life that she would not slow down, but despite her life being so busy and so full of tasks to complete, she not once describes even a moment’s hesitation at going with death. Perhaps she is easily seduced by the idea of death; perhaps she simply does not care about dying. Getting in the carriage with death is no bigger a deal than getting in the carriage with her father. As she sits in the carriage, she sees a school, children having fun, and beautiful facets from nature such as fields of grain. As the poem continues, her tone does not change, but the objects and places she is describing become further and further away, solidifying what Jack L. Capps explains as the showing of death being a significant theme that she does not mind leaving the aforementioned school and children playing for. Though the objects seem distant eventually and the sunset, Dickinson does not seem to care that she is
Water pollution is one of the main concerns of the environment. It is known as a change in the chemical or physical condition of the waters. Polluting the waters is causing harmful and tragic diseases that affect many families. It is also a global problem that not only affects people but also animals and plants. Water pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
Pollutants are the key elements of pollution, which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance of the environment. With innovation and development in our lives pollution has reached its peaks giving rise to global warming and human illness. When raw materials, water, energy and other resources are utilized more efficiently, when fewer harmful substances are substituted for hazardous ones, and when lethal substances are eliminated from the production process. Water pollution is also a major problem in the world because almost 60% of it is fish.
