Light Pollution And Its Effects On Health - 1544 Words

Most people have heard of air pollution, water pollution, and many kinds of pollution like them. Issues like these are covered extensively in the media and are targeted by many environmental groups. In fact, many of these issues play significant roles in political elections. Though these kinds of pollution are widely known, there is another type of pollution that receives far less attention. Few environmental groups mention it, and many members of the general public have not even heard of it. However, it is just as common and arguably as dangerous as the pollution types listed above. This pollution is known as light pollution. Fundamentally light pollution is the excessive use of light in urban areas, where growth of population and businesses brings with it large amounts of unneeded light. This light pollution causes countless negative effects ranging from the inhibition of scientific research to a believed negative impact on health. Light pollution s most notable effect, however, is on the night sky. As more and more lights are installed, more and more stars are blotted out by the resulting skyglow. Because of this, light pollution is by far the most severe impairment to astronomy at both the recreational and professional levels.

Trash Summary Free Essays

Trash Summary Trash is an epic novel about three ordinary dumpsite boys that sort through trash for a living. One day they find a key that leads them to a train station locker. From there they start the journey of their lives. We will write a custom essay sample on Trash Summary or any similar topic only for you Order Now Throughout the book many characteristics are shown both good and bad. I have chosen to talk about the themes trust and resilience. I chose these topics because I think both of these were shown many times in the book and they are to things that you need in every day life. Trust is the reliance that you have on one another, the belief that someone will come through for you in a time of need. This was shown many times in the book my favourite example was when Rat, (or Jun-Jun) was there for Raphael and Gardo at the beginning of the book they needed a place to hide the wallet. At any give time he could have gone straight to the police and turned in Raphael and Gardo.. Sister Oliver’s trust, pity and innocence led her to believing the three boys lie, this ended up putting her at great risk. Later on in the novel Gardo went back to the prison with the 20,000 pesos to give the guard for the bible. The guard tried to catch Gardo but he escaped just in time. I think this was a case where they were forced to trust the guard whether they wanted to or not, they had no option to get the bible or not. Resilience is the ability to bounce back and put up with severe amount of stress. That’s exactly what these boys put up with for the whole book, between being chased by corrupt police and breaking into a grave these boys had amazing mental strength. The best example of this is when Raphael got taken to the police station; he was tortured, beaten and almost killed. It took lots of resilience is just there will to see there adventure all the way through to the end. At any given time they could have quite gone to the police turned the other two in and made 20,000 peso. â€Å" We will fish for ever and live happy lives. That is our plan and nothing will stop us. † This quote said by Jun-Jun shows that the three boys trust each other to the end of the world. They would die for each other happily. They have been through so much mentally and physically that they could put up with anything. I honestly do think nothing will stop them. How to cite Trash Summary, Essay examples

Enforcing Morals free essay sample

This paper takes a look at the different philosophical theories of Lord Devlin and H.L.A. Hart at enforcing morals. This paper examines the theories of Lord Devlin and H.L.A. Hart Two British philosophers who analyzed the concept of enforcing morals. It takes a look at these theories as applied in contemporary British society, compares their contents and argues about the relevance of their application today. From the paper: Because of the diversity of cultural, ethical, and moral views and beliefs that obtain in contemporary Britain, the idea that the legal system may be used to legislate morality has become in the past generation ever more tenuous, casting doubt on both the philosophies of Lord Devlin and H.L.A. Hart. Both now seem to be limited in their philosophical application to legal and moral considerations in Britain in the 21st century; another way of saying this is to argue that when applied to British contemporary society Devlin?s theory on the enforcement of morality does not differ substantially from Hart?s at least in the legal implications of both.

Reasons for the American Revolution Essay Example

Reasons for the American Revolution Essay After the French and Indian War finally ended in 1763, France and England decided to sign a treaty called the Treaty of Paris. In the Treaty of Paris, France had to give England all of Canada and the eastern half of Louisiana. In exchange, they gained control of a few Caribbean sugar islands and two fishing islands along the Canadian coast. Spain gained control of the western half of the  Louisiana Territory. Spain also traded Florida in exchange for Cuba. The Mississippi River was left open to all of the nations. England’s victory in the French and Indian War had a great impact on the British Empire. But the cost of the war had greatly enlarged Britains debt. Plus, the war caused a lot of hate towards the colonists among English leaders, who were not satisfied with the financial and military help they had received from the colonists during the war. All these factors combined to persuade most of the British leaders that the colonies needed a major reorganization and that the central government should be in London. England first implemented the proclamation of 1763 which prohibited settlement passed the Appalachian Mountains. In 1765 Parliament passed the Quartering Act that said the colonists needed to find or pay for lodging for British soldiers stationed in America. With the French and Indian War over, many colonists saw no need for soldiers to be stationed in the colonies. The King and Parliament needed to get out of war debt which they mainly blamed on the colonists so they started to tax them. These taxes included the Stamp Act, passed in 1765, which required the use of special paper bearing an embossed tax stamp for all legal documents. Other laws, such as the Townsend Acts, passed in 1767, required the colonists to pay taxes on imported goods like tea. Many colonists felt that they should not pay these taxes, because they were passed in England by Parliament, not by their own colonial governments. The colonists started to re We will write a custom essay sample on Reasons for the American Revolution specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Reasons for the American Revolution specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Reasons for the American Revolution specifically for you FOR ONLY $16.38 $13.9/page Hire Writer
