The Impact of Global Warming on Human Health Essay

It tropical and sub-tropical climates temperature, humidity, and rainfall work together to create a breeding ground for mosquitoes. Mosquitoes are a host for communicable diseases one in particular is called malaria. Malaria is a parasitic disease that infects a particular type of mosquito, Anopheles mosquitoes, which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented (Global Health - Division of

The world has many years existing in this galaxy and every day we see that is changing more and more but not in a very good way that it can end in the extinction of the planet earth. “Earth Hasn’t Heated Up This Fast Since the Dinosaurs’ End” (Lavelle). Carbon is growing so fast in the atmosphere faster than in the past 66 million years since the dinosaurs went extinct (Lavelle). All the presidents hold a position of power that could change this big problem that the planet is having, behind this problem there is other problems that are causing a much bigger problem in all the country. “By year 2100, the average temperature will rise by 5.8 degrees as a result of global warming. The Arctic ice is melting rapidly. By 2040 the region is expected to have a completely ice-free summer, or even earlier. Since 1880, the average temperature has risen by 1.4-Fahrenheit degrees” (Rinkesh). Humans are the one in power of this planet, they are often making some decisions, but they do not know if that is going to hurt the planet. Also, is because humans are selfish. These decisions often include manipulating the system of other country, how they work, what products they can make, how to get benefit from that country, and etc. Also, taking control and/ or credit over other countries work. Some countries are taking very serious the Global Warming problem, so the other countries want a prove of how are they helping to fix this problem. Many countries have agreements with other countries that

(WHO 2015) It is now generally acknowledged that the global climate is changing as the earth becomes warmer, in particular due to the burning of fossil fuels. Human health may be impacted by shifting the geographic range and seasonality of infectious diseases, possibly increasing vector borne disease rates, disturbance of food-producing ecosystems, and increasing the frequency of extreme weather events such as droughts, cyclones, floods and bush

The World Health Organization (WHO) says as many as 4 million people could be infected in the next year in America. Subsequently, “On January 27th, Brazilian health officials reported a total of 4,180 cases since October 2015, and 287 more cases more cases a week earlier.” (Rosen 16). Health officials take a lot of time investigating many cases that have appeared in more than 20 countries, including the Caribbean, and Central and South America. The amount is rising more and more. In addition, the only places that were recorded to not receive the mosquito-borne virus were Canada and Chile, because of their lack of a large mosquito population. However, what does that mean for the

As a result of the mosquitoes physically being able to occupy a different vector, certain diseases also begin to expand to occupy that vector as well. As stated by an article about the population dynamics of mosquitoes, “global changes . . . lead to an extension of the distribution areas of certain mosquito species and the emergence of associated vector-borne diseases” (Ezanno et al.). As mosquitoes shift the vector of where they live as a result of this global warming, they bring what they have with them. In this case, this means that the mosquitoes bring these diseases with them throughout this new vector. Not only do mosquitoes bring these diseases with them to these new places, depending on the climate in this new area, certain diseases

Certain threats to human health loom larger with rising temperatures. Extremely hot temperatures can cause heat illnesses and loss of life. Several vector borne diseases only occur in warm areas, and an increase in temperature could mean a spread of these diseases to larger areas. Also, warm temperatures can increase levels of air pollutants, including ozone, which can harm human health.

In 2012, Texas encountered the largest outbreak of the virus with 1868 cases reported. During that year, the mosquito population increased drastically. This was because there were higher temperatures and fluctuations between rainfall and drought which provided ideal conditions for mosquitoes to reproduce. The drought conditions reduced water flow and created stagnant water

There are many diseases that thrive on climates which are warmer. Many of them become carried or spread to other countries that did not have them in the past because of the movement of people and goods. For example, the malaria and the dengue-carrying mosquito do not thrive in cold climates. They are found in tropical countries in Southeast Asia and Africa. But with the warming of the globe, suitable environments can be created for them in other nations.

A well-known mosquito-borne disease is West Nile Virus that is resurfacing because of heat and droughts. In the United States the worst recorded season was the summer of 2012 when 286 died from the virus. Ecologists are saying that in the north the season for the virus will last longer as climate change continues. It is predicted that in 2080 the virus could spread to southern parts of Canada as the Earth heats up.

From a scientific point of view, the author describes and substantiates the existence of global warming and also observes the potential effects it could result in. These include of rising sea levels, shifted climate patterns, increased threats to infectious diseases, extreme global temperatures, and coastal erosion. But ultimately, the report informs readers that the degree to which global warming affects life on Earth primarily depends on our decisions.

JE has two epidemiological patterns. Northern parts of Asia tend to see huge epidemics during the summer and the southern parts of Asia see endemics occur throughout the year with a spike during rainy seasons. It is said that temperature may be the reason for these differences. When the temperature gets cooler in the northern areas outside of the summer months, reproduction and development of the mosquitos slows, and transmission slows along with it. While in the south the temperature remains fairly constant throughout the year so this is not

Global warming is an increase in the temperature of the earth's weather. Global warming is also known as the green house effect. Global warming is a very serious world issue. Most humans are trying to do as much as they can to help stop global warming. Global warming has caused many problems to the earth in addition to the humans that live here on the earth. A problem caused by global warming is very hot summers. Some summers have had days that the temperature had reached 30*C. Another Problem that global warming has caused is the melting of polar ice caps. Global warming caused the polar ice caps to melt which will cause the ice to break free as well as melt in the sea, sea levels all over the world will rise. Lastly,

The number of mosquitoes increases with warmer temperatures and higher levels of rainfall, therefore there would be a rise in dengue fever cases. This article argues that although basic practices play a role in the outbreak, climate factors play an even greater role. The higher the temperatures the more likely persons are to store water. These are ideal conditions for mosquitoes to lay their eggs. This study showed that Caribbean Islands experienced an increase in the temperature by more than 0.5 degrees during 1900-1955 (Environmental Management Authority, (n.d). Also, if society does not cooperate with health personnel and take action starting with their immediate surroundings, then the efforts to contain this virus will not be successful.

The World Health Organization (WHO) defines global climate change as a large- scale change in climate patterns over the years, which includes changes in rainfall- and temperature- related greenhouse effects, where radiation gets trapped beneath the atmosphere. The average global temperature is predicted to rise 2.0 – 4.5˚C by the year 2100, which would have significant impact on vector-borne diseases. The temperature range for dengue is between 14 °C and 40 °C. With a 2 °C increase in temperature the extrinsic incubation period of dengue will be shortened and more infected mosquitoes will be available for a longer period of time. Mosquitoes will also bite more frequently because of dehydration and thus further increase man-mosquito contact (WHO, 2014)

In his article “Dengue Fever” John P. Cuhna describes Dengue fever, also known as “breakbone” or “dandy fever”, as, “a family of viruses that are transmitted through mosquitos”. This disease is very common in tropic and subtropic areas such as Brazil. Dengue Fever has no vaccination and the only way to prevent is to avoid getting bit by a mosquito that carries the disease. The disease comes from a mosquito known as the Aedes aegypti (Halstead, 2008). Since the climate and amount of rainfall are two key factors in the reproduction of the Aedes aegypti global warming and climate change have been playing a role in the dengue fever cases ( Halstead, 2008). This is a struggle for people who live in lower income and over populated areas since they have little to no form of protection and live in less cleanly areas. No one is exactly sure where dengue fever originated from but scientist recently proposed that it came from forests in Asia. Dengue fever has three stages; the first being the acute stage which can last from one to five days, the second is the critical stage which can last up to two to three days, and the last stage which is the recovery stage which is can last up to weeks.
