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. It also has a slew of other negative effects such as changing the habits of animals and contributing to an increase in cancer risk.

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

Infrastructure Developments Essays - Hong Kong, Geography Of China

Infrastructure Developments Essays - Hong Kong, Geography Of China Infrastructure Developments The Hong Kong-Zhuhai-Macao Bridge (HZMB) link roads of Hong Kong, Zhuhai and Macao The HZMB is of special strategic value in further enhancing the economic development of Hong Kong, Macao and the Western Pearl River Delta region (Western PRD). It will significantly reduce the cost and time for travellers and for the flow of goods between Hong Kong and the Western PRD, accelerating the economic integration of the PRD and its neighbouring provinces, and increasing its competitiveness. Construction of the project has started in December 2009 for completion in 2017. Meanwhile, the Hong Kong section of the Guangzhou-Shenzhen-Hong Kong Express Rail Link (XRL) will be 26-km long, running from the terminus in West Kowloon to Shenzhen, Dongguan and Guangzhou with significantly reduced journey time. More importantly, it will become part of the 16,000 km national high-speed rail network now being developed in full steam, fostering closer economic ties between Hong Kong and the mainland. Upon completion of the railway, the travelling time from Hong Kong to Beijing and Shanghai will be shortened to about 10 and 8 hours respectively. Construction of the project has commenced for completion in 2018. Besides the cross-boundary endeavours, the government has undertaken other large-scale infrastructure projects to improve the local transportation system, promote long-term development for arts and culture, and provide quality living space to citizens. As to the extension of the mass transit railway system, the West Island Line, the Kwun Tong Line Extension and the South Island Line (East) have been opened; while the Shatin to Central Link is expected to complete in 2021. The government has also announced the Railway Development Strategy 2014, providing a framework for planning the further expansion of Hong Kong's railway network up to 2031 to cover areas inhabited by about 75% of the total population and about 85% of job opportunities. Besides, a cruise terminal has been developed at the former Kai Tak Runway, with two alongside berths, well equipped with supporting facilities to accommodate the concurrent berthing of two mega cruise vessels (with gross tonnage of up to 220,000). As the busiest cargo gateway and one of the 10 passenger airports in the world, the Hong Kong International Airport needs an expansion since the existing two-runway system will reach its full capacity soon, according to the Hong Kong Airport Authority. The construction of the Three-runway System has started in 2016 for completion in 2024, with the commissioning of the new runway expected in 2022. Turning to the port, the government has released findings of the Study on the Strategic Development Plan for Hong Kong Port 2030 and the Preliminary Feasibility Study for Container Terminal 10 at Southwest Tsing Yi. The findings reveal that container throughput in Hong Kong will continue to see growth in the coming years. In order to cope with a projected future increase in throughput up to 2030, it is necessary to enhance the handling capacity of the existing container terminals and related infrastructural facilities, which include upgrading Stonecutters Island Public Cargo Working Area to a modern container handling facility for ocean-going or river trade vessels, enabling the River Trade Terminal to become a terminal for both ocean-going and river trade vessels, providing additional barge berths at the Kwai Tsing Container Terminals to relieve congestion caused by the increase of river cargo throughput, and making better use of land and other facilities around the terminals to enh ance operational efficiency and accommodate future growth in transhipment.

Dirty Water Bill Assignment Example | Topics and Well Written Essays - 250 words

Dirty Water Bill - Assignment Example This may lead to more damage downstream as these pollutants begin to accumulate. This policy as stated in the public outcry is literally similar to the notion of whatever happens in Vegas should stay in Vegas so this policy would fail quickly (Carter, National Wildlife Federation). H.R. 2018 bill was likely to threaten water quality in American rivers, streams, and lakes. The ability of federal and state governments would be limited in terms of ensuring that all American citizens can access clean water. The bill would limit the Environmental Protection Agency’s capability of revising an agreed water quality standard; this would happen only if the state agrees. It would prohibit the EPA from disallowing a water quality certification that is granted by a state. It would hinder the EPA from limiting federal financial aid for the state water quality program if a state does not comply with the water quality standards. Protected waters, aquatic waters would become degraded since the H.R. Bill 2018 renders EPA as somewhat meaningless. This includes weakening permit reviews that normally determine alternatives that do not harm the environment, do not go against laws, and do not degrade waters. H.R.
