volatile aromatic hydrocarbon can cause breathing problems as well as affect the central nervous system. Benzene is also another chemical found in crude oil that has been linked to birth defects and leukemia (the same leukemia that they are finding hard to get the drugs for). Hundred of cleanup workers in the state of Louisiana have reported suffering from headaches, vomiting, difficulty breathing and severe chest pains (Khan, 2010). Pollution in general can cause lots of health problems which includes: respiratory problems, possible birth defects and it can also cause different kinds of cancers (Buzzle, 2010).

Then there the issue of global warming; which also affects the health of all life on earth (World Health Organization, 2010).

“Global warming is not only a threat to our future health, it already contributes to more than 150,000 deaths and 5 million illnesses annually, according to a team of health and climate scientists at the World Health Organization and the University of Wisconsin at Madison—and those numbers could double by 2030”(Larry, 2010).

Scientists have been monitoring the growing impact of global warming on the health of people living in different regions of the world. It has been realized that the people most affected by this growing problem of global warming are those people living in the poor countries. They found this very ironic because these people are the ones who contribute the least to the problem of global warming as it is right now. Yet they are the most susceptible to health risks and possibly death as a result of this dramatic change in the earth’s climate (Larry, 2010).

The increases in temperatures mean that there is also an increase in the number of disease borne insects (Buzzle, 2010). This was the case this year with the dengue fever carrying mosquito.

According to Martin Krause, UNDP’s Bangkok-based technical advisor on climate change for the Asia-Pacific region, “A major public health threat is coming from the vector-borne disease that depends on temperature and on humidity” (Heller, 2010).

The reason why the change in climate can increase the risk of dengue fever is because global warming is causing the increase in the variations of mosquitoes. The warmth of the climate is a key contributor in facilitating the survival of the mosquito species (Heller, 2010).

“The UN Intergovernmental Panel on Climate Change’s Fourth Assessment Report summarized research showing that various arthropods that carry vector-borne diseases, such as ticks, mosquitoes and sandflies, have all been moving into more northern latitudes in response to recent warming” (Varner & Gale, 2010).

Several studies have been done by public health researchers, in relation to the connection between the dengue virus risk and the change in climate, and it was found that vapor pressure accounted for 89 percent of the circulation of the dengue cases. This team of researchers projected that by 2085, the world’s population at risk for dengue would have doubled (Heller, 2010). There are quite a number of health issues that can arise from the infection of dengue fever; it is not called the break-bone fever for no reason. Although it has been said that you cannot die from dengue fever, some persons develop ‘Dengue Haemorrhagic Fever’ and in some instances people do die as a result (World Health Organization, 2010).
