Negative Impacts of Donald Trumps Wall

Negative Impacts of Donald Trumps Wall The Negative Repercussions of a â€Å"Yuge† Wall in America: U.S-Mexico Border Increasing border security has been an ongoing discussion in the United States for many decades, particularly in recent months since the 2016 election year. The elected president, Donald Trump, used this matter to garner supporters during his campaigning, and since elected, has still been a proponent with constructing a border wall between Mexico and the U.S. There is a notion from this perspective that with a higher and stronger border, undocumented immigration will halt and supposedly will allow America to be â€Å"great again†. The president elect initially sought for the funding of the wall to come from Mexico, nevertheless, that funding has now shifted to the U.S. Congress paying for it and claiming that Mexico in some form or another will reimburse the costs of the construction. Increasing border security through this â€Å"wall† however, will bring even greater conflicting issues such as environmental damage, increase the dangers of the lives of immigrants when a ttempting to cross, and unreasonable costs to create and sustain this wall.   The effects will negatively impact this nation’s reputation, building this wall is the wrong thing to do even though the â€Å"American thing to do† has been to increase border security.

Securing the Unites States border between Mexico has been a developing matter through history since the Treaty of Guadalupe was signed in 1848 that allowed the acquisition of new territory and the Rio Bravo becoming the political border line between these two countries. Movement through this border has always been present, shifting in its increase due to economic hardships whether in Mexico or United States such as the bracero program where the U.S. requested help from Mexican farmers to work their lands due to shortage of labor because of their involvement in World War II [1]. However, Mexican immigration did not end once the war was done. President Eisenhower administration executed the Operation Wetback, â€Å"a governmental campaign that forcibly repatriated 1 to 2 million Mexicans [whether undocumented or not]†[2]. Despite the force, immigration from Mexico and Central America has yet continued. Before the 1990’s, immigration crossings in the U.S – Mexico border had waves coming in through urban crossing points such as El Paso – Ciudad Juarez, San Diego – Tijuana, McAllen – Reynosa, etc. Nonetheless, the United States government implemented fence-buildings, closing off these urban crossings points, influencing a change of routes into dangerous points such as Arizona’s desert[3]. With putting up barriers at these points, â€Å"deaths in the border region have increased nearly 150% as migrants enter through more remote and rugged terrain† in the last decade and half [4]. Dead bodies of unknown immigrants have been found throughout these harsh geographic areas. As depicted in the picture, these graves show the sacrifice these immigrants will put their lives in[5]. The construction of this proposed wall, will unquestionably further the risks that immigrants will challenge when trying to cross to the United States, still placing themselves through deserts, underground tunnels, and even sea. These environmental situations have been counterproductive to the â€Å"securing†, alternatively, creating inhumane barriers for immigrants whose goal is to have a better life on the other side of the border. The proposed wall not only will create needless dangers to humans crossing attempts, but an environmental effect for the flora and fauna found and living in this region.   Wildlife had not been thought through when these fences were implemented having to only take account humans as the focus for these constructions, being â€Å"motivated by security concerns that are considered paramount over most other considerations†[6]. Since the border fences and security of the 1990’s, immigration crossings did not decrease but rather shifted from urban areas to the remote areas where the ecology is most concentrated[7]. Research has shown that the fence border that is suited between Mexico and the United States has indeed â€Å"disrupted movements and distribution of [for instance], animals such as the ferruginous pygmy owl and bighorn sheep and could isolate small populations of large mammals in Arizona, including black bears and pumas†[8]. By building the wall, it will disrupt evermore the ecology, inhibiting wildlife to move naturally within its natural habitat[9]. Environmental activists and communities have been vocal over the repercussions that the wall will bring to the environment and the dangers that the threatened and endangered species will have to face from this development. Species such as the ocelot and jaguarondi (wild cats) that â€Å"are tropical species at the northern limit of their natural habitat range, the barrier would †¦certainly expedite the disappearance of these species from the U.S.†[10]. However, the Trump administration has ignored these environmental consequences in recent news. Even so this avoidance has been seen during the early 2000’s, where â€Å"federal legislation adopted [to sideline] all environmental laws such as the Endangered Species Act† for the sake of not disrupting the â€Å"construction of the barriers†[11]. Protecting the environment and preserving species in their natural habitats allows for the ecosystem to flow accordingly, if disrupted, humans will be effected since they’re dependent as well to these natural habitats. It would be selfish and vicious for humans who coexist with these variety of species to construct an artificial border that will knowingly harm them.   Photo of alleged smuggler transporting a Central American family to along the border near Mission, Texas in July 2014, Photo Credit by: John Moore/Getty Images http://latinousa.org/2014/09/12/smugglers/. The wall project that will stretch 2,000 miles will evidently create more damage but as well be costly and ineffective[12]. $21.6 billion has been a recent cost projection for the construction, with perhaps putting the United States into more debt[13]. This billion-dollar wall will not stop undocumented immigration since those who enter the United States come in with visa and outstay their visit, [outnumbering] those who cross the border without permission[14]. This gives an example of the forthcoming ineffectiveness of this wall that these billions of dollars will go into when comparing it to today’s border fence that hasn’t necessarily stopped undocumented immigrants from coming from the south of the border. Another matter as well, as Josiah McC Heyman explains in their journal, â€Å"human smugglers have apparently kept ahead of the government, despite the post-1993 tactical shifts, added technology, and the buildup of forces†[15]. Such as the picture above, t hese human smugglers or coyotes as they have been named as, have found ways in the last two decades with smuggling unauthorized immigrants into the United States, despite the increase of money and labor that has been put for the â€Å"securing† of the U.S. – Mexico border since its construction in 1993[16]. Immigrant individuals or families will give thousands of dollars to these coyotes to sneak them across the border, putting their lives into these individuals’ hands for a better life than the one they had in their home country.   In addition, patrolling the extent of this 2,000-mile border wall will need additional border patrol agents. The Trump Administration is considering hiring another 5,000 agents, significantly increasing their budget to hire, train and maintain these agents, with an estimate of $328 million for 2017 and 1.884 billion dollars for the year of 2018[17]. Hiring these much personnel will not come easy, these patrol agent applicants must go through extensive training and tough exams where hiring them can take about seven months[18]. With shortening and easing the processes, however, could do more harm than good since they will not have the adequate training to patrol rough and dangerous terrain. Thus, building this wall as Trump has been consistently vocal about doing will only bring predicaments to the United States economic condition, since this proposed funding will not bring much triumph with stopping undocumented immigrants from coming into the country. With this wall, it would only reflect irrational money waste to the eyes of the national and international public, disregarding other departments such as education and health that would most benefit and outweigh the 20-billion-dollar funding for the greater future of the country. Most undocumented immigrants who are coming from Mexico, Central America and other South American countries are trying to flee either poverty or violence or even both. It is human nature for people to want to push forward with their lives to seek a better future for themselves and/or families even if it means putting their lives at risk for days in the harsh terrain that this border is located at. Building this massive wall will not stop immigrants from trying to go over, under, or around it, but rather do more harm to the environment, economy and people. The â€Å"American Thing Do† has been to spend billions of dollars to not necessarily â€Å"secure† our border, but rather to stop people from seeking the American Dream. This nation has been built by immigrants and no shape and form will people stop immigrating to this melting pot of a nation. It is in the nation’s interests to change its perspective on immigration, a comprehensive immigration reform and assist ance to these underdeveloped countries would do more justice for its self and other countries.

The Great Dr. Jose Rizal

â€Å"It is a useless life that is not consecrated to a great ideal. It is like a stone wasted on the field without becoming a part of any edifice. â€Å" Jose Rizal, a man with so many accomplishments, gives all of us inspiration to put diligence and hard work in all the things we do. I am amazed that even though Rizal’s life has become sort of a series of unfortunate events, he still made it yield a positive and favorable outcome for his nation and countrymen. While he was in exile, he didn’t mind the fact that he was sent to Dapitan to live like a prisoner and yet he still managed to become abundantly fruitful with varied achievements for he practiced medicine, pursued scientific studies, continued his artistic and literary works, widened his knowledge of languages, established a school for boys, promoted community development projects, engaged in farming and commerce and many others. Despite his many activities, he kept an extensive correspondence with his beloved family, relatives, fellow reformists, and his friends who were eminent scientists and scholars of Europe. It is only when it was mentioned in the documentary have I realized that Rizal never left the country to his own purpose and advantage, but to extend even greater his sacrifice for the sake of the Filipinos. Rizal truly was a person for his countrymen, he truly was a patriot and nationalistic for he never wanted to see his fellow countrymen being oppressed and being exploited -what made Jose Rizal stand out of the others as a hero to a nation. He truly was a man of action, he did not only look over the people nor just tell people what to do, and he helped them in their everyday work. Rizal was intelligent and yet very humble. He always put his countrymen first before him as well he never failed to express how he loved so much his family and the people he held close to his heart through his letters to them all throughout. These are credible and more than enough reasons for me to justify that Rizal is our hero, our inspiration and our lesson of the past that just like him, we should also strive hard to live honorably and be a man for our country.

Studying Fossil Fuels Use In Singapore Environmental Sciences Essay

Singapore is a little state with no natural resources, it is important to diversify the state ‘s energy beginnings so as to guarantee that this will non restrict Singapore ‘s economic fight and growing. Currently, the gas-fired power works generates 80 % of the state ‘s electricity and the staying 20 % coming from the oil-fired power works [ 1 ] . The Energy Market Authority ( EMA ) has predicted that there would be an increasing gas ingestion demand in the electricity sector [ 2 ] . Therefore, there is an increasing demand to look for other energy beginnings such as coal and liquefied natural gas ( LNG ) , and besides atomic energy in distant hereafter [ 1 ] . In add-on to happening the alternate energy beginnings, safeguarding the environment is besides an of import undertaking for the state. It is reported that electricity coevals histories for about half of the C dioxide ( CO ­Ã‚ ­2 ) emanation in Singapore [ 3 ] . Therefore, there is a demand to look for cleaner fuels in order to cut down C dioxide emanations so as to minimise its part to planetary heating. This paper will give an overview of the hazards, impacts, advantages, every bit good as the disadvantages of utilizing coal and LNG as alternate energy beginnings in Singapore. Coal Coal is a non-crystalline solid fuel which consists of chiefly C formed from the remains of organic affair under the Earth ‘s surface for 1000000s of old ages. It besides contains trace sums of sulfur, quicksilver and radioactive stuffs. Hazard and Impacts of Coal One of the hazards associated with the usage of coal as energy fuel is that coal degrades in reserves upon subjugation to weathering and atmospheric oxidization. This implies that the belongingss and constructions of stored coal can be altered and therefore, doing them less valuable for intended usage. Therefore, in order to keep the belongingss of the majority coal, big coal atoms with smaller surface-to-volume ratio are preferred since a smaller overall effectual surface country slows down the rate of debasement. However, larger coal atom size would ensue in more null infinite, taking up valuable storage infinite, bring forthing less energy per unit volume which leads to higher transit costs [ 4 ] . In the event that smaller coal atoms are employed alternatively, oxidation and debasement of coal would take topographic point at a faster rate due to increased effectual surface country. This may bespeak that coal is non suited for usage under Singapore ‘s clime of high humidness degrees which aggravate the coal debasement job. Coal has high oxidization affinity which could ensue in self-generated burning during storage [ 4 ] . Heat coevals can happen from the exothermal oxidization reaction, and wetting ( heat of wetting ) . While the rate of heat dissipation is slower than the rate of heat coevals, heat build-up occurs. This frequently leads to self-generated burning that may be hard to command one time a reserve gimmicks fire [ 4 ] . The issue affecting coal debasement is that dust atoms would be released when the coal is exposed to environment [ 4 ] . The production of all right atoms would degrade air quality and can trip societal wellness concerns, particularly when inter-building distance is smaller in Singapore. It would decline the wellness conditions of people who are enduring from lungs- and eye-related wellness jobs. Having assessed the hazards affecting the usage of coal, the impacts associated are besides analyzed. If stored in unfastened reserves, the coal is non merely subjected to weave eroding which will increase particulate pollutants in the air, but besides rains that are frequent in Singapore ‘s clime that will do coal pile overflow. The H2O oozing through the hemorrhoids would fade out or leach heavy metals and toxic organic substances within, and finally travel into the belowground H2O, which may do its manner to reservoirs and H2O catchments. Contaminated H2O can do farther societal wellness jobs and would be damaging to marine aquatic life. Besides the issue related to char storage, combustion of coal can take to serious environmental jobs. 20 % of the planetary nursery gas emanations emitted are the consequence of coal firing [ 5 ] . In United States entirely, 51.6 metric tons of quicksilver were released into the air yearly from coal power Stationss [ 6 ] . It will be expected that more quicksilver is released if Singapore increases her use of coal. Mercury is toxic and poses a menace to both human species and marine beings. Accretion of quicksilver in the organic structure can do harm to encephalon and kidneys. Singapore has ratified the Kyoto Protocol in 2006, which has ordinances on emanations and in consequence, punishments have to be paid for emanations [ 5 ] . This would be a great impact when Singapore adopts coal power because it has significantly more emanations compared to oil and gas. Punishments for CO2 emanation are expected to increase over clip due to more rigorous controls in topographic point, and would likely do coal power less attractive as an alternate fuel for energy variegation. Advantages of Coal Due to the high handiness of coal, the cost of coal is low compared to natural gas or crude oil. Based on research carried out by Massachusetts Institute of Technology ( MIT ) , the cost of coal is ~ $ 1-2 per million BTU, compared to $ 6-12 per million BTU for natural gas or crude oil [ 7 ] . Therefore, the usage of coal enables a lower capital investing in the natural stuff. Greater nest eggs from procurance of low-priced natural stuff enables better flexibleness in investing for pollution control in cut downing CO2 emanation. Coal militias could last much longer than gas and oil. In order to enable Singapore to prolong long-run energy demands, a dependable supply of fuel is a cardinal consideration. Harmonizing to probes carried out, the ratio of the militias to production rate ( based on the current ingestion tendencies ) has revealed that coal could last for another 155 old ages, which is much longer than in the instance of oil and gas ( 40 and 65 old ages severally ) [ 6 ] . Si ngapore can see coal as one of its option in energy beginnings variegation since the low cost and durable supply of coal render it attractive, and therefore makes Singapore economically more competitory [ 8 ] . Coal is a major beginning of energy in many states like China, US, and India. As the supply will non run out in the close hereafter, researches are proactive to develop advanced clean coal engineerings, including gasification and liquefaction for C dioxide gaining control and storage [ 7 ] . Furthermore, the lifting costs of oil and gas as a consequence of depleting beginnings would force the development of such engineerings at a faster rate, doing coal power emanations comparable to oil and gas power. China as the universe largest coal consumer would unlikely halt the use of coal. Alternatively of change overing to alternative cleaner fuels that may incur substructure costs while decelerating down its advancement, research on advanced methods for continual use of coal at a much lower emanation would be developed by them. With new methods being developed, coal power emanations would be of all time diminishing along the clip line [ 7 ] . For case, CO2 Capture and Storage ( CCS ) which is presently in development is expected to do coal power a feasible power option with an expected 20-60 % addition in usage compared to today ‘s degree. With CCS, CO2 emanations from firing coal can be reduced to merely half to a 3rd of the sum of emanations today, which makes it comparable to CO2 emanations from burning of gas and oil at present times [ 7 ] . Disadvantages of Coal Despite the fact that coal is lower in cost, the comparative energy content per unit weight is low excessively [ 4 ] . Sing two indistinguishable trucks transporting the same volume of coal and crude oil, the truck transporting crude oil gives higher energy output content. Consequently, higher cost is incurred in the transit of coal. Currently, H2O conveyance offers a lower cost alternate to railway, but there is an increasing ordinance on fuel for Marine conveyance, which will further increase cost of coal transit. Stocking of coal requires stock heap direction, which would likely be much more strict than anyplace else as land is scarce in this state [ 5 ] . Coal storage is comparatively land area-intensive. Other considerations include the clime of Singapore, which rains are expected to happen often, unfastened hemorrhoids are improbable to be considered. Storage in enclosed silos or sand traps would, nevertheless, incur higher capital costs and can restrict enlargement capablenesss. Gas fired power workss emit 70 % lesser CO2 per unit of electrical end product, and petroleum-based systems emit 50 % lesser CO2 than coal-burning power [ 7 ] . LIQUEFIED NATURAL GAS ( LNG ) Liquefied natural gas is natural gas that undergoes liquefaction and it consists chiefly of methane. During the procedure of liquefaction, drosss like H2O, N, C dioxide, H sulphide and other S compounds are removed. The beginnings of gas are well-diversified. Soon, the type of natural gas used in Singapore is the Piped Natural Gas ( PNG ) obtained from Indonesia and Malaysia. Singapore considers LNG as an alternate energy beginning as it starts the building of the liquified natural gas terminus in Jurong Island, so as to purchase gas from Qatar, every bit good as other possible LNG providers such as Australia and Oman [ 2 ] . Hazards and Impacts of LNG The hazards involved in LNG prevarication in its containment and handling. Under ambient temperature and force per unit area, natural gas in its liquid signifier occupies 1/600th times the volume of its tantamount gas signifier. If LNG were to get away into the ambiance, it will zap rapidly taking to the undermentioned jeopardies: ( 1 ) formation of a gas cloud with many times the volume of associated LNG which may attach to with hazards such as fire or detonation ; ( 2 ) terrible brickle break harm to reaching stuffs such as C and low metal steel constructions at cryogenic temperature ; ( 3 ) terrible hurt to personnel coming into contact with the cryogenic stuff [ 9 ] . The release of LNG would non ensue in fire unless it is exposed to an ignition beginning when its volume in air is between 5 % and 15 % [ 10 ] . If this happens in or near to residential part, the abodes who face the fire would have thermic radiation harm. In instance if LNG escape were to go on in the cloaca systems, it would bring forth flammable bluess that would detonate under parturiency and doing farther harm [ 9 ] . In add-on, vaporized LNG can do suffocation when released into a confined country as O concentration is reduced. During the transit of LNG, oilers are comparatively vulnerable to transgress by hit with heavy supplanting ships even if at the most moderate velocities. Such incidents are likely to happen within port where heavy supplanting ships and LNG oilers portion the same operating environment. In add-on, spillage can happen when LNG oiler travels through difficult point obstructors ( for case, concrete hemorrhoids and stone pinnacles ) . Upon impact, terrible harm to the bottom construction of the LNG oiler could ensue in interior hull incursion. Nevertheless, hazard of major spillage can be greatly reduced the two-base hit hulled design [ 9 ] . Singapore ‘s displacement in accent to LNG has raised the concerns of general public with respects to the storage and transit of LNG, particularly after some efforts of onslaughts by terrorists. However, for the same ground stated under hazard of loss in containment of LNG, pure methane will non light in the presence of an explosive charge without premixing with the right proportions of air. In instance of terrorist onslaught, the likely consequence on LNG installations would be a big pool fire alternatively of an detonation. Hence, LNG armored combat vehicles and oilers are non attractive marks for terrorists who seek to execute monolithic devastation to population lives [ 11 ] . Advantages of LNG Singapore depends on natural gas and crude oil as its chief beginnings of energy supply, which makes these options vulnerable to monetary value fluctuation and supply break. Therefore, LNG offers the chance of significant variegation off from current fuel supplies, enabling Singapore to keep its security of supply while maintaining electricity costs every bit low as possible to maintain concern and consumer costs down. The providers of LNG are good diversified as identified earlier. Hence, LNG may easy be available in copiousness. Even though LNG is a non-renewable resource, its supply worldwide is sufficient to run into the demands of Singapore for the following two decennaries, harmonizing to EMA [ 12 ] . Compared to other fossil fuels, LNG is considered as an environmentally-friendlier and cleaner fuel. LNG contains about wholly methane and no other drosss such as metals, sulfur and N since the liquefaction procedure has removed such drosss from natural gas to forestall solids formation as the gas is refrigerated. As such, LNG burning will surely ensue in less air pollution and lower C dioxide and azotic oxide emanation every bit good as atom emanations. In add-on, the emanations of sulfur dioxide are besides negligible compared to char and oil. Hence, the usage of LNG will assist to cut down jobs of acerb rain and nursery consequence. Due to the high volatility of LNG, it will non blend with H2O or dirt in instance of spillage on H2O or land. Alternatively, it will vaporize and disperse rapidly into the air without any residues. Water and land pollutions are therefore avoided. In footings of flammability, LNG has higher flammability bound ( 5 % ) compared to other fuels like Liquefied Petroleum Gas ( LPG ) ( 2.1 % ) or gasolene ( 1.3 % ) . This implies that for a given volume, more LNG bluess are required to light. Besides, LNG vapour has the highest autoignition temperature ( 1004 oF ) compared to other liquid fuels like LPG ( 850-950oF ) , gasolene ( 495 oF ) and diesel fuel ( about 600oF ) . Since LNG occupies 600 times less infinite than natural gas at ambient conditions, less storage infinite is required. It is besides easier to transport LNG though grapevines than natural gas. In footings of energy coevals, LNG has high net energy output. Hence, the usage of LNG will give higher efficiency compared to oil in power works. Disadvantages of LNG Although LNG is considered as a cleansing agent fuel, it besides contributes to planetary heating to a little extent. Methane, which is the chief component in LNG, is besides a nursery gas which will increase the methane degree in the ambiance if released. In tropical part like Singapore, one definite challenge is to maintain LNG as liquid. This could imply a important sum of energy ingestion to take down the temperatures of the LNG armored combat vehicles [ 13 ] . In order to keep LNG as liquid without excessively much chilling, expensive substructure is required for LNG storage and transit [ 11 ] . Economically, the operations of LNG are capital intensive due to big sum of disbursals needed for the building of liquefaction installations, transit grapevines and purchase of specially designed oilers and LNG ship. High transit cost of LNG from other states to Singapore constitutes portion of the cost excessively. Furthermore, being the lone receiving and regasification terminus in Singapore, the LNG terminus may monopolise LNG supply. In other words, the users may hold to bear higher monetary values. Even though LNG oilers and installations are less likely marks for terrorists, any successful onslaught could ensue in loss of substructures that are highly valuable. Therefore, seashore guards are needed to guarantee the safety and security of the LNG oilers. By beef uping security along coastlines and port installations, Acts of the Apostless of terrorist act and incidents can be prevented. However, while guaranting larboard security is indispensable, transportation paths are every bit vulnerable. If any incidents or onslaughts were to happen in the center of a sound, LNG supplies and all other flows of trade via the same transition would be disrupted. Decision Coal is the cheaper signifier of energy that is besides extremely abundant. It could, nevertheless, degrade when exposed to oxygen, ensuing in it being a hapless quality fuel. Due to take down energy content per unit volume, coal would take up big storage infinites in land-scarce Singapore. Environmental pollution could originate from the release of coal dust which is a menace to public ‘s wellness. Heavy metals and other drosss found in coal are harmful pollutants that are likely to be released upon debasement. However, development of new clean-coal engineerings can be expected from big coal consumers such as China, US and India. Like coal, Liquefied Natural Gas ( LNG ) will help Singapore in get bying with the demand in electricity as a cleansing agent and abundant signifier of fuel. The monopolization of LNG terminus in Singapore could, nevertheless, unfavorably consequence in consumers paying higher monetary value for LNG fuel. The storage infinite for LNG is much smaller than natural gas, which fits good for Singapore whereby land is scarce. When assorted in 5 % to 15 % with air, LNG will light upon exposure to an ignition beginning. Most of all, LNG is a much cleansing agent and efficient signifier of energy compared to other fuels and burn with minimum atom residues and environmental pollution. The hazards associated with the handling of coal and LNG can be minimized by following with industrial criterions and ordinances. While the clime of Singapore disfavours the storage of both coal and LNG, the scheme for energy variegation utilizing these two options shall render our energy system resilient for the following 20 old ages.
