Man’s Effect on the Environment
1) SOURCES OF POLLUTION
Freshwater Environments : Man pollutes freshwater all over the world in many ways there is much waste and pollution that ends up in rivers.
One of the main hazards is called eutrophication, this process becomes enriched with artificial nutrients from fertilisers which run off into the rivers and upset the natural nutrient cycle of the river, lake or pond. The water turns green because of the algae which when they die multifly using up all the oxygen.
Similar consequences occur if raw sewage is pumped into a river.
Chemical waste from factories dump their un wanted waste into rivers, lakes or ponds as well. One major component that effects the water wildlife is the insecticide DDT which damages animal tissue and is dangerous to humans , this can be passed along the foodchain.
Marine Environments : 80% of the waste which is pumped into the sea each year is produced by dredging, 10% is industrial waste and 10% is sewage. Some of the consiquences due to this are :- presence of toxic substances and the rapid uptake of contaminants by marine organisms to name but a few. Oil spillages either by tankers or offshore ridges cause devistating effects on the local environments. Oil is extremely dense which means it floats on top of the water and can kill fish and birds, ruin beaches but nothing as yet has been invented to deal with this major problem. Dangerous metals such as mercury, arsenic and lead are also dumped into the sea. All of these examples have the ability to kill and damage the environment around it.
Agricultural Environments : Unwanted plants or insects are nowadays killed with by herbicides and insecticides, in this case chemical rather than biological are used. Pesticides have the ability to damage the local environment, while herbicides may kill wild flowers as well as weeds and insecticides may kill

harmful pests but it can also kill butterflies and moths. Some of these chemicals are even dangerous to humans as well.
2) FIVE MAJOR POLLUTANTS:
SULPHUR DIOXIDE
Sulphur Dioxide comes from both car and factory emissions.
Sulphur Dioxide is a poisonous gas which can kill plants and is the main gas that is involved in Acid Rain.
Oil

...he U.S, Britain, Canada and Russia. It is not as efficient as coal as a fuel because it has a high water and ash content.
Wood this is a good Biofuel as it provides 13% of the world’s energy. As wood is used so much in the poorer countries and is insufficiently burnt resources are slowly decreasing in such countries as Africa and Asia. Nowadays there are special trees which can grow more quickly therefore it is possible in the right plants wood can produce substantial amounts of energy.

Alcohol can be made during fermentation and can be used in cars as fuel. It’s main advantage is that it is more enviromentaly friendly. It can also be used to make such things as perfumes, lacquer and explosives.
8)POLITICAL INVOLVEMENT :
The Government wants more people to do more in the way of giving the poorer waste food and say that we should help them as much as we can. The government has also set up charities which raise money in order to give help to
particulary the extremely poor countries by using T.V adverts to raise the money. Oxfam is possibly the most well known charity that helps poor countries, Oxfam however mainly helps such countries as India and Africa.
Throughout the years I have been cheering, all of my family and friends have supported me. Cheering may not be the most traditional sport that my parents may have wanted me to be a part of, but it is the sport that has brought many good memories to me. Making new friends that have he...
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.
Louis Armstrong was born on August 4, 1901, in New Orleans, Louisiana, in the impoverished part of town, often called “The Battlefield”. He had one sister, Beatrice, who was born in 1903. His father, William Armstrong, was a factory worker and his mother, Mary Albert, resorted to prostitution to provide for the family after his father left. Because of this, Armstrong was often left with
Harmfull Effects of Ocean dumping include animals in danger with trash in their habitat, as well as contamination of public waters.
and is existing surely because of humans themselves- overpopulation. “Overpopulation is the problem” and causes other externalities such as pollution, deforestation, and a greater handful of biodiversity losses. In addition, overpopulation causes economic and political factors such as more consumption per person and the reduction of resources that can be provided per person. This contributes to the strain on ecological systems and the economic and population growth. With overpopulation, many resources become finite and an umpteen amount of ecosystems are being destroyed. Overpopulation relates to the impact of humans on pollution. Obviously with more human life, there is more necessity for jobs such as factories that give off fumes, automobiles, and the use for burning fossil fuels. In greater extent, this leads to an environmental factor in that it accumulates chemicals in food chains such as mercury, arsenic, and copper. It can lead to political problems as well, when trying to interact with other countries and stop the problem of global pollution and eventually endin...
In the book the Life of Pi by Yann Martel, religion plays an important role in Pi’s life. When on the lifeboat, Pi used his faith as a way to motivate himself to live. Without his religious beliefs, there is no way to guarantee he would have made it off the lifeboat.
Water pollution has had devastating effects on the environment, which include irreversible effects to the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousand of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever; unless there is a balance. We must protect the resources we have in order for them to last into the next generation. Every time we throw away a plastic bottle, drive our cars, and even burn those millions of fossil fuels to operate all those huge factories, there is a chance it will pollute the ocean and eventually effect the way we live. There should be stricter laws regulating human pollution, in order to protect our oceans ecosystem.
Cheer, a diverse and dangerous sport is a very foggy subject for many. The majority of the population would say cheer is just a group cheering on a sports team. Before being able to define what cheer is, one must first look at current day competitive cheer. How cheer gained its stereotypes lays in its history, and rapidly evolved into a completely different function. With cheer being the number one cause of sports injury for girls under twenty, twenty thousand deaths from stunting, and seventy percent of girls sports injuries in high school, the statistics raises an eyebrow as to just what cheerleaders are doing. Cheer went from chants, to stunt groups, to worlds championships in just a century.
The famous British feminist and magic realism author Angela Carter, was born on May the seventh of 1940 in Eastbourne, United Kingdom to Sofia Olive and Alexander Carter. In an article called The Guardian written by Edmund Gordon, praised Angela Carter and said that she, “was one of the most important writers at work in the English language.” Her upbringing and hardships inspired her imagination for her works about feminism, sex, love, and so much more has become an inspiration to many readers. Books like Night At The Circus, The Bloody Chamber, and Fireworks allow young adults to really go deep through their imagination.
Cheerleaders all share the same love, cheering; there is always excitement about being known as a cheerleader. Sometimes cheering can be a good and bad thing, but in the end it 's never a boring activity. With tons of people in the crowd, just staring at you waiting for what cheer you will call next, waiting to see who will mess up first, or who will say the wrong words. So many things going on at a football game, yet all you can do is stand there, look pretty, and smile.
Pollution is causing the destruction of environments and habits resulting in many adverse affects. The types of environments that are heavily damaged by pollution is normally freshwater ones. Polluting factors such as untreated sewage, mining waste, acid rain, fertilizers and pesticides
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
Transportation is a big issue with pollution. Vehicles create smog, catalysts for ozone, and components for acid rain. Smog contains a chemical called ozone. Ozone can seriously affect a human’s health. It reacts with the molecules in the lining of our airways. This then causes inflammation. Acid rain has many ecological effects, but none is as bad as its impact on lakes, streams, wetlands and other bodies of water. Acid rain makes waters acidic, which causes them to absorb the aluminium that goes from soil into water. When bodies of water become more acidic, the numbers and species of fish and other organisms living in the water begin to decrease. There are many examples of water pollution. Raw sewage running into water, industrial waste spills, and exhaust fumes from vehicles. A big problem with raw sewage is that Bacteria use up oxygen in the water, as they decompose the organic material in the water. The lack of oxygen kills animals and other organisms that live in the water. Many harmful chemicals are in industrial waste. These can become drinking water pollutants if not well managed. Car exhaust creates a wide range of gases and solid matter. This causes global warming, acid rain, and it harms the environment and human health. Engine noise and oil spills also cause pollution. Since most oils float, the marine creatures most affected by oil spills are animals like sea otters, and seabirds that are found on the shore or in
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
Alcohol is a class of organic compounds that is characterized by the presence of one or more hydroxyl groups (-OH) attached to a carbon atom. Alcohol was unknowingly produced centuries ago when fermentation occurred to crushed grapes (Pines, 1931). In today’s society alcohol is produced for the use of household products such as varnishes, cleaning products, but is more commercially important in the liquor business. A chemical process called fermentation accomplishes the production of ethanol, the alcohol or liquor. From there, the ethanol goes through distinct processes to become the dark and clear liquors on the store shelves.
