Cause And Effects Of Smog Pollution Environmental Sciences Essay

Cause And Effects Of Smog Pollution Environmental Sciences Essay Smog pollution is a major problem that this planet is suffering from everyday. It has affected our homes, weather, and health. It is a very dangerous situation for us if we do not do anything about it. Smog pollution is caused by chemicals, automobiles, factories and corporations. The greatest thing we can do as a society is try to find a way to help prevent and stop smog pollution. If the people on this planet do not do anything to stop smog pollution we are going to have a BIG problem and it will hurt us in the future. We need a plan and we need to put a stop to smog pollution. The American Lung Association (ALA) has been trying to find ways to help stop and prevent smog pollution from hurting us and the environment. If we can just do our part and find a way to prevent this problem from getting any bigger, it will benefit us all. We all have heard of smog pollution, but do we really know what it is. Smog pollution has many causes that can be hazardous and dangerous to our health a nd well being. The term smog pollution is also known as photochemical smog. It is formed by the interaction with sunlight with different types of chemicals in earth’s atmosphere (Oblack). The main component of smog pollution or photochemical pollution is ozone. Ozone is in the earth’s stratosphere, which the shields the earth from dangerous UV radiation from the sun. The problem with ozone is when it touches down on the earth’s surface it can be very dangerous and can cause serious health problems for people on the planet (Oblack). The ground level ozone is made by the emissions of automobiles that put nitrogen oxide into the air, which is caused by the vehicle’s exhaust fumes (Oblack). The organic components from the fumes combined with the ozone and fume evaporation that combines with sunlight, causes smog pollution on the planet (Oblack). Many people try to find ways to help avoid smog in a more planet friendly environment, so some people use substitut es for their everyday use. There is just one problem with that, and that is the sun. Many people don’t understand that sunlight and warm climates cause pollution. For example, places like California, Florida, and Arizona and even North America are some of the most polluted places in the country (Oblack). Another problem that causes an increase in smog pollution is the increased usage of fossil fuels for industrial, heating, and of course transportation purposes (â€Å"All that smog†). Also, cutting down, burning trees, and disposing of agricultural and organic waste can also lead to emissions of smog pollution and harmful problems for the planet (â€Å"All that Smog†). Sunlight mixed with different types of dangerous chemicals (secondary pollution) also makes it difficult to stop smog pollution from occurring on the surface of the planet (â€Å"All that Smog†), which creates another big problem. Climate is a major factor for the cause of smog pollution. M any places in the world can try to be more environmental friendly to help save our planet. Some people ride bicycles instead of driving cars. Other people try to reduce their use of using fire to warm themselves. The only problem that these people cannot get away from is something that they cannot control, and that is the sun. California is ranked in the top 10 most polluted areas in the United States. Ozone pollution that is caused by the sun has a major affect on this planet. Smog and air pollution is having a serious impact on the environment and can condemn all ecosystems (â€Å"seirraclub†). The reason why the sun causes so many problems is because the ozone layer that is supposed to protect planet earth is practically destroyed. Without the protection, the sun is able to shine radiation onto the planet and is the main reason for many health issues that people go through every day. Issues like skin cancer, radiation poisoning, and sun burn are having fatal affects on peo ple. This type of pollution not only harms humans, but it can also harm wild life and the environment. Smog can harm different plants, which can lead to damaging consequences. Because the plants are damaged, it makes it hard for plants to make and save food for themselves in their living environment (â€Å"seirraclub†). In addition, the sun and smog can destroy leaves and plants it would make many of the plants vulnerable to getting diseases. And, they cannot defend themselves from different types of bugs and insects that can cause a huge decrease in plant life (â€Å"seirraclub†). Smog pollution is a yearly problem for places like Texas, Georgia, Florida, and many other southern and sunny parts of the world, but there is also a big increase in smog pollution in the summer (â€Å"seirraclub†). This is caused by strong sunlight that burns the earth’s surface. However, the one thing that is helping smog pollution is all of the problems that are on this plan et. All of the power plants, automobile emissions, industrial, and chemical vapors are other causes of pollution (â€Å"seirraclub†). Climate changes are part of the problem as well. Within the months of June, July, and August, it makes it harder to try and control the smog pollution, due to the sun. This planet has gone through billions of years of evolution. It survived dinosaurs, the ice age, and the black plague, but because of smog pollution this planet might not be able to survive this new attack.

John Dewey Essay Example | Topics and Well Written Essays - 1250 words

John Dewey - Essay Example The community as a whole, through formal laws and customs, codifies behavior that ultimately commits individuals to a specific course of action. Such predictable actions are required for community life. The schools function as socializing agencies, internalizing the child's recognition of social duties and the will to carry them out. Dewey insisted that social ties, like the parent-child relationship, are natural. The mutual responsibilities corresponding to these specific stations are therefore intrinsic and binding. By nurturing the social spirit of the child, an habitual disposition to act out of social service and for the common good will becomes manifest. Pursuit of self-advantage and infidelity to one's social responsibilities is a primary evil according to Dewey. Freedom and social responsibility are not incompatible. Social authority is natural and inevitable, not a necessary limitation on personal freedom. Throughout his writings, Dewey retained the Hegelian insight that man achieves human qualities and fulfillment by participating in the enhancement of community life. Individuals should identify the social good as their own true good by perceiving the values and common interests that bind people together. Their freedom and happiness ultimately depend upon it. Individuals should obey the la... However, in advocating policy changes, they must persuade others voluntarily. The burden of proof is upon them to demonstrate how a specific law or practice fails to serve the common good. Dewey's theory of democracy was designed to reconcile freedom with authority, social stability with the need for reform, and universal standards with specific circumstances. He substantively refined Lockean individualism, which is popularly associated with the modern liberal tradition. Dewey comprehensively applied these insights to the reform of education. Once again, many critics mistakenly identify him with the radical, subjectivist approach of progressive education. Dewey denounced the progressive educator's romantic fetish for the "natural child." The child-centered school provided no standards at all; logically it culminated in anarchy. Proper teacher authority and a well-structured curriculum were indispensable. Dewey argued that, "to fail to assure them guidance and direction is not merely a permit to operate in a blind and spasmodic fashion, but it promotes the formation of habits of immature, undeveloped, and egoistic activity." (Dewey, 1930) Indulging a child's selfish whims would lead to an arrest of growth and the disintegration of personality. The development of mental powers follows certain laws of growth. The fact that a child might desire something does not mean that it is in fact desirable. That judgment can be determined only after critical reflection. (Dewey, 1929) The glorification of the spontaneous and immediately enjoyable also stunted the child's capacity to understand contemporary social life. These students were not socially responsible or cognizant of the forces of industrial civilization. While

Human and Plant Physiology - Coursework Example The mesophyll tissue, which is made up of spongy cells, and palisade cells contain a huge number of chloroplasts. Chloroplasts contain chlorophyll (a green pigment) which absorbs light energy during photosynthesis. The leaf’s palisade tissue contains the greatest concentration of chloroplasts and it is in this tissue where most photosynthesis takes place (Adds, Larkcom, and Miller 2004, p3). Explain the Exchange of Oxygen and Carbon Dioxide between the Plant and Its Environment Gaseous exchange indicates the exchange of oxygen and carbon dioxide between the plant and its environment or surrounding. There are two processes of gaseous exchange, photosynthetic gas exchange and respiratory gas exchange. In photosynthetic gas exchange, carbon dioxide is taken up and oxygen given off by the plant. On the other hand, in respiratory gas exchange, the plant takes up oxygen and gives off carbon dioxide. The process that predominates at a certain time can be determined at the leaf surfac e of the assimilating plant. Respiratory carbon dioxide escapes when it is dark. Under optimal conditions for assimilation, photosynthesis is maintained by the utilization of carbon dioxide set free through respiration. This state of compensation is only evident when the process of gas exchange is shut off. It is important to note that gas exchange between the plant cells and its surroundings or the environment takes place by mass flow and diffusion (Larcher 2003, p91). Explain the Uptake of Water and Minerals by the Plant After the diffusion of mineral-rich soil water into the roots, the water reaches the vascular cylinder of the root through two ways, (a) by diffusing through the cell wall, and (b) by moving through the cytoplasm. Water enters the cytoplasm through the diffusion across the plasma membrane of the cell in the root’s cortex or epidermis. Dissolved mineral cannot diffuse because the membranes are impermeable to ions (Evers, Starr, and Starr 2010, p418). Mineral ions enter the cytoplasm through the active transport process in the plasma membranes. In the cytoplasm, ions and water diffuse from one cell to the cell through plasmodesmata until they enter the vascular cylinder. After water and ions enter the vascular cylinder, they are distributed to the other parts of the plant by the xylem. The plant’s cell wall is rigid but permeable to ions and water. Soil water can enter vascular cylinder by direct diffusion through the cell walls. The parenchyma cells in the root cortex are tightly packed, and they create a continuous pathway that permits the diffusion of mineral ions and water into the vascular cylinder from the epidermis. It is important to note that soil water diffusing into through the cell wall enters the vascular cylinder through the endodermal cell cytoplasm (Evers, Starr, and Starr 2010, p419). Analyse the Benefits of Exercise and the Problems Associated With Obesity There are numerous health benefits of exercise. Exercise can minimize major illnesses such as stroke, diabetes, cancer, and heart disease by up to 50 percent. Exercise can lower up to 30 percent the risk of early death in an individual. Research indicates that physical activity or exercise can boost mood, energy, sleep quality, and self-esteem. Physical activity has been shown to reduce the risk of depression, Alzheimer’s disease, dementia, and stress. People who do exercise regularly
