Agent Orange was a riot control agent also known as a RCA. (Goldlust Chemical warfare p.111) Agent Orange, named for the orange stripes on the 55-gallon drums it was stored in, is a powerful defoliant that was used by the U.S. during the Vietnam War. Agent Orange served many purposes such as killing plants that would have otherwise been used as cover for the enemy, bombing rice fields to starve the

Non-steroidal anti-inflammatory medications (NSAIDS) are used to treat arthritis and pleurisy. Costicosteroids creams used to treat skin rashes, an anti-malaria drug called Plaquenil and low dose corticosteroids are sometimes used for skin and arthritis symptoms. This auto-immune disease can affect almost every organ in the body causing a variety of health complications. Another interest surrounding the issue of treating lupus is diet. No processed sugars and other high glycemic starches because they increase inflammation.
John Knox Anastacio, McCord 11-19-10 Humanities 1-2 The Everlasting Drug War Throughout history the poppy flower has been considered to be a gift from God. Once the 19th century arrived, scientists discovered Morphine and Heroin. Morphine and Heroin were scientific miracles at the time, but later became a curse on America. Soldiers during the Civil War did not have the medication needed in order to survive. Morphine allowed doctors to perform surgery on injured soldiers and not just amputate their body parts.
Name: Fayaz Shaikh Prof: Leo Zwischenberger Subject: English 114 “Ethics of Fracking” Fracking is actually drilling for gas, it’s not a normal drilling. It uses very harmful chemicals that are injected deep in earth, almost five to eight thousand meters. Those chemicals crack to rocks to obtain natural gas. As this provide so much gas to United States, it’s been used here for sixty years. It also have some very harmful effects on humans and nature.
The samples were tested for the presence of 155 chemicals known to cause cancer in laboratory animals, respiratory diseases and endocrine system disorders, said Rachel Morello-Frosch, an associate professor at UC Berkeley's Department of Environmental Science and Policy Management and the School of Public Health. ( Bay City News, 2008) Roughly half of these samples were found to be over the safe quality standards of California which excludes the inside levels. Some of the pollution that was found by this analysis was from traffic toxics caused by highways but the greater part was from the oil refining. Much of these toxins are known to cause cancer and other harmful diseases to the populace. The refinery has devoted many millions of dollars in strategies to control pollution since its creations, yet before the safety regulations of the country were passed.
Research Paper There are many things that are detrimental to our health. Some of these things are natural, like viruses and bacteria and some of these things are man-made, like guns and cigarettes. Why would we create things that could ultimately kill us? People are driven by all sorts of things and one of the biggest things is greed. Tobacco, and specifically cigarettes, have been the most detrimental, but preventable thing to our health in the United States for the years they have been around.
With the depletion of the forest that converts the carbon dioxide into oxygen it has monumental negative effects on the planet as a whole. “Eleven developing countries recently linked to 82 percent of the carbon dioxide buildup due to deforestation will likely come under the greatest pressure for change: Brazil, Indonesia, Colombia, Cote D’Ivoire, Thailand, Laos, Nigeria, Vietnam, Philippines, Myanmar (Formally Burma) and India”. (“cooper”) One of the major locations deforestation is in the south Asian country Thailand. “Located wholly within the tropics, Thailand encompasses diverse ecosystem, including the hilly forested areas of the northern frontier, the fertile rice fields of the central plains, the broad plateau of the northeast, and the rugged coast along the narrow peninsula.”(“Thailand”). Since the formation of the country Thailand
Renewing the natural ecosystem for a healthier food chain 11 CONCLUSION 14 APPENDIX 15 REFERENCES 16 INTRODUCTION In Vietnam, during the period of 1961-1971, American army sprayed more than 80 million liters of toxic chemical substances, most of which were Agent Orange which contained about 400 kilograms of dioxin. This weapon of mass destruction has caused great suffering to countless families and left serious consequences on the natural environment and generations of Vietnamese. For the time being, it is estimated that there have been 4.8 million Vietnamese people victimized by Agent Orange/dioxin. They reside mainly along the Trail of Truong Son and in areas bordering Cambodia. Tens of thousands of them have died.
