Environmental Issue Essay Example for Free

Environmental Issue Essay The current concern of our environmentalist nowadays is how to bring back the bountiful natural resources of our venue of living before. This is just a dream but this can be true because nowadays everything is possible. It is, indeed, a great challenge of this environmentalist to provide solutions of the problems manifested in our environment. Before presenting my arguments, I would like first to secure the parameters of this debate. I limit this debate to one of the hottest issues in the environment which is Air Pollution. Air Pollution is the human introduction into the atmosphere of chemicals, particulates or biological materials that cause harm or discomfort to humans or other living organism. Looking at the status quo, it is obscene that there are a lot of sources that made our air contaminated. First point, I content that the severity of catastrophe happened in our environment deeply rooted from anthropogenic sources (human activity) such as â€Å"Stationary Sources† as smoke stacks of power plants, manufacturing facilities and municipal waste incinerators. â€Å"Mobile Sources† as motor vehicles, aircraft etc., marine Vessels such as container ship or cruise ships and related port air pollution, burning wood, fireplace, stoves, furnaces, fumes from hair spray, varnish, paint, aerosol spray and other solvent, oil refining and industrial activity in general. These things respond the question of why our air is being contaminated. Second point, I would like also to argue that the government plays a vital role in protecting our environment. The government has the prowess to make some possible and practical solutions of environmental problems. They have enough budgets to initiate some activity and project that would cater the protection and preservation of our natural resources. To sum up my arguments, first the main problem is the human activity that deteriorates our environment and second is the irresponsible action of the government. We can make a difference as by letting ourselves as an example because change starts in ourselves. http://en. wikipedia. org/wiki/Air_pollution#Sources This page was last modified on 22 March 2008, at 18:53.

Acid Rain :: essays research papers fc

Acid Rain INTRODUCTION: Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it's own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from the sky onto our planet that contains an unnatural acidic. It is not to be confused with uncontaminated rain that falls, for that rain is naturally slightly acidic. It is caused by today's industry. When products are manufactured many chemicals are used to create it. However because of the difficulty and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of the lakes were beginning to show signs of death. Fish were found dead along the banks of many rivers. As the winters ice began to melt off more and more hundreds upon hundreds more dead fish (trout in particular) were being found. It was at this time that scientist began to search for the reason. As the scientists continued to work they found many piles of dead fish, up to 5000 in one pile, further up the river. Divers were sent in to examine the bottom of the rivers. What they found were many more dead fish. Many live and dead specimens were taken back to labs across Norway. When the live specimens were examined they were found to have very little sodium in their blood. This is typical a typical symptom of acid poisoning. The acid had entered the gills of

Gumamela Flowers as Alternative Perfume

â€Å"Gumamela Flowers as alternative perfume† Members: Jozelle Omania Mark Andrew G. Jupida Jimwel C. Ocharona Peter Paul A. De Vera Prince Acee T. Santos Book: you and the natural World Series Biology   html Date: 11/29/12 Statement of the problem: This study Gumamela flowers as an alternative perfume aims to have a fragrance which is safe, effective and environmental friendly. Based from: Biology book and internet Introduction Hibiscus rosa-sinensis, known colloquially as the Chinese hibiscus, China rose and shoe flower, is an evergreen flowering shrub native to East Asia. It is widely grown as an ornamental plant throughout the tropics and subtropics. The flowers are large, generally red in the original varieties, and firm, but generally lack any scent. Numerous varieties, cultivars, and hybrids are available, with flower colors ranging from white through yellow and orange to scarlet and shades of pink, with both single and double sets of petals. Despite their size and red hues attractive to nectar-feeding birds, they are not visited regularly by hummingbirds when grown in the Neotropics. Generalists, like the Sapphire-spangled Emerald, Amazilia lactea, or long-billed species, like the Stripe-breasted Starthroat, Heliomaster squamosus, are occasionally seen to visit it, however. In the subtropical and temperate Americas, hummingbirds are attracted to them on a regular basis. Meaning Hibiscus rosa-sinensis is one of many plant genera with a genetic characteristic known aspolyploidy, in which there are more than two complete sets of chromosomes, unlike most other species including human. Polyploidy is a condition where the phenotype of the offspring may be quite different from the parent, or indeed any ancestor, essentially allowing possibly random expression of all (or any) of the characteristics of all the generations that have gone before. Because of this characteristic, H. osa-sinensis has become popular with hobbyists who cross and recross varieties, creating new named varieties and holding competitions to exhibit and judge the many resulting new seedlings and often strikingly unique flowers. To add to the genetic opportunities, Hibiscus rosa-sinensis has been successfully hybridized with the cold-hardy Hibiscus moscheutos and several other North American Hibiscus species, producing cold-hardy hybrids (see cold-hardy Hibiscus cultivars). Making perfume from G umamela is a popular science project for children due to reasonably easy process that is involved. Before you begin making Gumamela perfume you will need to make sure that you have the correct ingredients and equipment. You will need:†¢ One cup of gumamela flowers (a type of hibiscus)†¢ Five by five inch of muslin pouch†¢ A rubber band†¢ Half an ounce of gumamela essential oils†¢ Two quart glass bowl†¢ A potato masher†¢ One cup of distilled water†¢ One quarter of a cup of ethyl alcohol and a 20 oz spray bottle. If this experiment is being carried out for a child's investigatory project, make sure that they are supervised by an adult at all time.Once all of the ingredients and equipment has been collected, the following steps can then be carried out.†¢ Fill the muslin pouch with the cup of gumamela flowers. Secure the pouch with the rubber band and place it in the glass bowl. You can then add the cip of distilled water to the bowl and microwave the bowl for around four minutes.†¢ Remove the bowl from the microwave and mash the musli n pouch with a potato masher within the bowl. This will express the essential oils that are contained within the pouch of flowers.This should be continued until the water has gained a reddish pink hue. The pouch can then be discarded and the liquid poured into the spray bottle. †¢ Add the ethyl alcohol and gumamela essential oils to the spray bottle. The oils help to enhance the aroma of the perfume and also help it stick to the skin. The ethyl alcohol can be replaced with water for those with sensitive skin but this will create more of a body spray. The lid can then be placed on the spray bottle and the whole think shaken vigorously for a few minutes to blend everything together.

Edna Pontellier of The Awakening A Woman before Her Time...

Edna Pontellier is a woman of great needs. Although she has a husband who cares for her and two children, she is very unhappy. She plays her roles as a mother and wife often, but still keeps doing things unmarried, barren women should do: enjoy the company of other men, ignore her childrens cries, dress unladylike for the times. The story is set in the late 1800s, when women were to be in the kitchen preparing a meal for their family, giving birth to more children to help with daily chores, or sitting quietly at home, teaching the children while the husband was at work. Edna Pontellier was a woman not of her time.

Edna not only has Madame Ratignolles f riendship and her marriage to wake her up to her dreams and emotions, her affairs wake up to her desires. The way the different male characters treat her reminds her that she will never happily fit into the role of a wife and mother, therefore awakening her. Leonce Pontellier was Ednas husband and the father of her children. Although she was married to him, it was not by her choice. Her oldest sister, who had stepped into the role as her mother when their mother died, and her father had the biggest say in whom Edna was to marry. Her marriage to Leonce Pontellier was purely an accident, in this respect resembling many other marriages which masquerade as the decrees of Fate (23). In the 1800s, women were perceived as property. They were first the property of their fathers, then property of their husbands - whoever was chosen by the parents for the women to marry. Leonce was in love with Edna, and had been since they met. Although she never quite felt as strongly, she was pleased and flattered by his absolute devotion (24). After they married, in spite of her unentertained heart, they had two boys.
