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)
Deforestation is the permanent destruction of forests in order to make the land available for other uses. Half of the world’s tropical forests have been cleared or degraded. Some people ask why forests’ are being cleared. It is typically done to make more land available for other things like housing, cash crops, oil, and cattle ranching. Most of what everyone does with deforestation is said to be illegal. Common methods of deforestation are clear cutting and burning trees. The burning method can be done either quickly or slowly. Quickly for plantation use or more slowly using the slash and burn technique. The many reasons why farmers and other people do that is to get money to feed there family or like it was stated early, to make room for growing crops or livestock. Forests are cut down for many reasons, but most of them are related to people’s need to provide for there families or money. Logging operations, which provide the world’s paper and wood products, also cut a number of trees down each year. Loggers, some of them doing it illegally, also build roads to get to more and more remote forests, which leads to further deforestation. Not all deforestation is a terrible thing and intentional. Deforestation comes in handy when in need to build a new oil place. There are a lot of natural factors that play into deforestation like wildfires and subsequent overgrazing. Most of the deforestation occurs in the tropics, which is a terrible place because they have poor soil for
Deforestation has been a major concern in tropical rainforests, this is an act of destructing a forest for multiple reasons including wood supply, agriculture purposes or the extraction of minerals and energy. Forest loss till date is 18.03 million acres per year and it has been estimated that within 100 years all rainforests will be destroyed.
Every single day, the Amazon Rainforest is losing a massive amount of area due to deforestation. The Amazon is the world’s largest tropical rainforest and it is the world’s source of oxygen. Deforestation has slowed down years ago, but now, it is starting to increase and does not show that it will slow down. Earth without tree’s, the human race and animals would not be able to survive. Today’s society is not taking deforestation as a serious matter. If deforestation were to be left alone, the planet and animals would not be the only ones suffering from it. Deforestation is a big issue that has to be made known and find a solution to end it. The causes and the effects of deforestation should be made known to the society and the importance
Aside from expediting the extinction of animal and plant species in the rainforest, deforestation is also playing a major role in global warming. In the time before the coming of humans, it was the
Rich black soil, towering tropical trees, the distant sound of a hollering monkey and the smell of damp leaves paint the picture of a tropical rainforest. The most famous and valuable tropical forests include the Amazon, Congo Basin, Indonesia and the forests of the Russian Far East and have been debated as endangered for decades. These rainforests mainly differ in soils, geology, precipitation patterns, the wildlife which resides there but all share the abundance of natural wealth including sturdy woods, medicines and spices and are sought out by many. However the long debated question still stands if deforestation is something of the past or an on going and current threat.
Malaria is considered the most important vector-borne infectious disease in the world, which is caused by a species of the Plasmodium parasite, and transmitted by female Anopheles spp mosquitoes.2,10,12
Malaria is becoming more prevalent in Nairobi and Indian villages in the Amazon because the of the human changes to ecosystems. In Kenya, malaria is spreading from the countryside to its major cities from citizens making the move from rural to urban areas. This is occurring because rural areas are becoming more polluted and less profitable for its inhabitants. These people moving from rural areas bring with them malaria carrying mosquitos to the shanty towns that surround the city. These shanty towns contain many gardens that provide the perfect breeding ground for the infected mosquitos. The introduction of these mosquitos into cities like Nairobi has drastically increased malaria prevalence in Africa. In South America, the spread of malaria has been linked to the rapid deforestation that is occurring in the Amazon. Scientist have studied water samples throughout the malaria hot zones and have found mosquito larvae only in waters that are located in deforested area. The shift in the ecosystem from rainforest to clear cut cow pasture has allowed for better breeding condition for mosquitos. These conditions in deforested areas have caused a massive up rise in the number of malaria cases in the region.
Malaria is one of those diseases that have stood the test of time, and still of major concern in many regions of the world, especially in tropical areas. It is an intermittent and remittent fever caused by a protozoan parasite that invades red blood cells. Malaria affects approximately two hundred and fifty million people annually, with the morbidity burden felt most in the tropics. Children under the ages of five and pregnant women in Sub-Saharan Africa are the groups most affected by this disease. Malaria is the leading cause of death from parasitic infection worldwide, with approximately one million deaths each year. Most of these deaths occur in Africa, followed by South East Asia.
Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases
Malaria is caused by a parasite that is transmitted to a person through the bites of an infected female Anopheles mosquito. Like other mosquitos, Anopheles goes through four stages in their life cycle: egg, larva, pupa, and adult. The first three phases are in water and last 5-14 days, based on the species and the ambient temperature. The last phase is when the female Anopheles mosquito functions as malaria vector. The female Anopheles mosquitoes need a stagnant, polluted environment to reproduce. This is
Malaria is a severe tropical illness spread by mosquitoes. If malaria is not detected and
For those who don’t know what malaria is, malaria is a deadly disease that was once has taken many lives, long-forgotten in this day of age. Malaria once considered as one of the world 's most dangerous parasitic diseases in the tropical continents. Malaria has claims more lives than any other
Where malaria disease is found depends mainly on climatic factors such as temperature, humidity, and rainfall. The main areas where malaria disease is found are; Africa, Madagascar, India and South America. Malaria is transmitted in tropical and subtropical areas, where the host mosquito, of the genus Anopheles, is able to survive and multiply. There are approximately 430 Anopheles mosquito species, only 30 to 40 of which transmit the malaria parasite.
