Engulfing the Congo and the Sub-Saharan regions of the African peninsula, a new threat has emerged; lying below the mucky surface of a deforested plain, a killer has taken root. At risk is half of the world’s population who reside in the 106 countries and territories that are prone to plasmodium falciparum transmission. Who is this killer? Anopheles gambiae complex, which has devastated the African region acting as a vector for the parasite plasmodium falciparum, more commonly referred to as malaria. Why has a parasite that is responsible for approximately half of all recorded deaths relatively unheard of in Western civilization? The answer lies with the deforestation and non-sustainable practices that plague the African union. …show more content…
Annually, 200 million malaria cases are contracted and of these, 90% occur in Sub-Saharan Africa. Approximately one million people die annually, making plasmodium falciparum the most deadly parasitic disease. Contraction of plasmodium falciparum begins when a female Anopheles mosquito injects sporozoites, an early form of plasmodium falciparum, into the host. This sporozite is then transported to the human liver where it undergoes asexual reproduction producing merozoites. The merozoites invade other liver cells and enter the host’s bloodstream, where they invade erythrocyte. After the infection of the erythrocyte, the merozoite is transformed into a trophozoite, which then begins asexual reproduction near the nucleus to form a schizont in the erythrocytic cell. The schizont then asexually reproduces to produce mononucleated merozoites. When the erythrocytic cell ruptures due to the 3,000-4,000 merozoites produced, symptoms of fever and chills are induced within the host. This life cycle is extremely damaging to children; persons under the age of 5 account for 86% of malaria fatalities. Malaria has other characteristic effects, such as yellowing of the skin/eyes (jaundice), sweating, vomiting, weakness, and nausea. Current mortality rates in Africa are 9.33% per 1000 children, which represent 28.2% of all fatalities for those under five. The story changes dramatically as the host
Ecological factors that encourage the Anopheles mosquito, and thus also encourage the prevalence of malaria include: being near the equator, densely populated areas, warmer temperatures, standing water, maintaining water for irrigation and deforested areas. (Holy p.1)
Jefferson Davis and Abraham Lincoln both had some similar views when it came to the issues of secession. Jefferson Davis was a southern born man who believed in the ideas of states rights just as all the other southerners did. However, he did not support the ideas of secession. He was a part of the senate and trying to preserve the union, but when his home state of Mississippi seceded he followed and resigned his position of the senate to join their efforts. Lincoln, like Jefferson, also did not agree with the ideas of secession.
Background - Malaria is a water borne disease. It is spread by a parasite-carrying mosquito. It kills many people and reduces a country 's capacity to develop. There are different strategies to combat malaria. Around half the population is at risk of malaria and this disease is active in 106 counties across Africa, Asian and the Americas (see source 3). the global annual mortality from malaria is between 1.5 - 3 million deaths, or between 4000 and 8000 each day. Developing countries are most vulnerable to Malaria and as shown on source 2 Malaria has been spread across many various other countries including in Europe, but these countries have eradicated Malaria.
In Middle and South America, it is evident that human interactions affect the physical features. The human interaction that affects Middle and South America is deforestation. In 1970’s a period of deforestation began in Brazil with the construction of the Trans-Amazon Highway; the road allowed migrant farmers to grow crops (Pulsipher & Pulsipher 2012). Deforestation continued throughout Middle and South America. The use lodging of hardwoods, extracting minerals, oil, gas, stones and clearing off land for raising cattle, and growing crops has impacted most of the land in Middle and South America (Pulsipher & Pulsipher 2012). The human interaction of deforestation has led to many environmental issues, changes in physical features. There are loss
Banquo, a noble and honest man, was also killed at the orders of Macbeth. Although, the depth of Macduff’s loyalty to Banquo is not very clear, Banquo’s murder is part of the reason he fought vehemently against Macbeth. Macbeth saw Banquo as the man “which would be feared” (Shakespeare 88) for he seems to be faultless. Banquo is inquisitive, brave, honorable, willing to take risks or “dares” but also knows when to play things safe. A seemingly perfect person like Banquo is undoubtedly troublesome to a flawed being like Macbeth, for they bring righteousness with them which signals the flawed one’s downfall. Macbeth says to the murders that Banquo’s existence “thrusts/Against my near’st of life”(Shakespeare 92). Banquo’s existence proves to be
Malaria has been a huge problem among many developing nations over the past century. The amount of people in the entire world that die from malaria each year is between 700,000 and 2.7 million. 75% of these deaths are African children (Med. Letter on CDC & FDA, 2001). 90% of the malaria cases in the world are located in Sub-Saharan Africa. Once again, the majority of these deaths are of children (Randerson, 2002). The numbers speak for themselves. Malaria is a huge problem and needs to be dealt with immediately.
Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.
Plasmodium a single-cell parasitic protozoa is transmitted to humans via the bite of an infected female Anopheles species mosquitoes. This can lead to potentially fatal parasites, rapidly multiplying in the liver attacking red blood cells resulting in symptoms arising from cycles of fevers, chills, severe headaches, vomiting, jaundice and diarrhoea. One major disastrous symptom includes sweats accompanied by anaemia, cause damages to vital organs and interruption of blood supply to the brain, which could result in incurable illness leading to fatal death. In very severe cases it can cause seizures, comas or even death. Symptoms usually present between ten to fifteen days after the initial infection. Unlike other diseases, Malaria can represent in people months or even years later. Death rate is approximately 1%-5% due to the spread of Malaria in Afghanistan, affecting each and everyone.
Advocates for the preservation of these forests state that deforestation has devastating consequences including social conflict, extinction of plants and animals, and dangerous climate changes, and that local deforestation in these forests are causing damages that aren’t just local, but global. While opponents claim that tropical forests are destined to diminish as it is necessary for the growing human population to clear the natural landscape to make room for farms and pastures, to harvest timber for construction and fuel, to build roads and urban areas and to develop the economies of the often poor countries that surround the equator.
U…….U〜n …… It’s suffocating. Similar to falling into a deep, deep bottomless swamp, stifling like this….. Haa!
Deforestation is commonly known as the removal of trees or forests from an area which is transformed into a non-forested area. The most concentrated deforestation occurs in tropical rainforests. According to the UN Food and Agriculture Organization, Nigeria’s land covered by forests shrank from 14.4 percent to 9.9 percent between 2000-2011 (FAO Country Programming Framework (CPF), 2013-2017). Furthermore, Global Watch Forest reported that Nigeria lost a total of 567,371 hectares of the forested area out of 10,048,732 hectares as of 2016. According to the U.N. FAO, only 9.9% or about 9,041,000 ha of Nigeria is forested. Between 2000 and 2005, Nigeria lost 55.7% of its primary forests, and the rate of forest change increased by 31.2% to 3.12% per annum (Ogundele & Adebisi, 2016). There are several causes of deforestation in Nigeria but this paper will discuss some major ones, followed by their overall impacts. Furthermore, this paper will also attempt to discuss some solutions and recommendations to combat deforestation in Nigeria.
Wildfires are commonly caused by human activities especially during the dry season. Deforestation is also common as local use the wood for fuel and for building. Deforestation is also caused by the growing population and the increasing need for new infrastructure such as houses.The land depletion has led erosion to be common as well. Land doesn’t have roots to hold on causing soil to displace, taking with it necessary nutrients. This has caused patches of infertile land across the dry deciduous forest of Madagascar. The follwowing picture was taken at the Anjajavy Dry Forest. Because of its proximity to villages and the frequent use of slash and burn agriculture, a large portion of its surroundings have been affected by desertification and
In September of 2013, I was living in the Eastern Region of Ghana among the green, tree-decorated mountains. Within a few days of my arrival, however, my young host sister came down with a fever and chills: telltale signs of malaria. This came as no grand surprise, as West Africa has long been recognized as an endemic region. However, as we drove to a nearby chemist to retrieve a dose oral antibiotics, my host father described the changes he’s observed in Ghana’s malaria since he was a child – and this was startling. He illustrated the discrepancy between the way the land appears now and how it did in times past, suggesting that these alterations are connected to transformation in malaria incidence. Palm oil, pineapple, and cashew plantations replace the once-thick natural forests of the mountains. My father explained how the foliage has become sparse and spotty compared to the dense jungles that enclosed the village when he was young. A popular rodent forest-dweller used for food became endangered as their habitat was destroyed. The new roads which wind to and from the new farms are littered by puddles, and as my father said gravely, there is more malaria.
Malaria is one of the most severe public health problems worldwide. It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected. According to the World Health Organization’s World Malaria Report 2013 and the Global Malaria Action Plan , 3.4 billion people (half the world’s population) live in areas at risk of malaria transmission in 106 countries and territories. In 2012, malaria caused an estimated 207 million clinical
About 3.3 billion people, that is about half of the world’s population are at risk of contracting malaria (figure 1). Every year there are 250 million cases of malaria, and nearly 1 million deaths. That amounts to 2,732 deaths per day. Out of those million people that die every year, 800,000 of them are African children under the age of 5. To control malaria three actions need to be taken: insecticides need to be used to decrease the vector population, people have to be educated as to how to prevent the vector from reproducing, and anti-malarial drugs need to be distributed. To understand the vector and what the vector is, scientists had to first discover what the parasite was and how it worked. It was not until the year 1880 that French Physician Charles Laveran discovered that Malaria was caused by a protozoan in the genus Plasmodium (Malaria, 2013)
