4.0 Influence on Human Health

a. Heat-Related Death

Exposure to extreme heat can lead to heat stroke and dehydration, as well as cardiovascular, respiratory, and cerebrovascular disease. (USGCRP, Global Climate Change Impacts in the United States., 2009) Excessive heat is more likely to affect populations in northern latitudes where people are less prepared to cope with excessive temperatures. Certain types of populations are more vulnerable than others: for example, outdoor workers, student athletes, and homeless people tend to be more exposed to extreme heat because they spend more time outdoors.

Low-income households and older adults may lack access to air conditioning which also increases exposure to extreme heat. Additionally, young …show more content…

Extreme weather events can also disrupt or slow the distribution of food. (USGCRP, Impacts of Climate Change on Human Health in the United States: A Scientific Assessment., 2016)] Higher air temperatures can increase cases of Salmonella and other bacteria-related food poisoning because bacteria grow more rapidly in warm environments. These diseases can cause gastrointestinal distress and, in severe cases, death. (USGCRP, Impacts of Climate Change on Human Health in the United States: A Scientific Assessment., 2016)

Practices to safeguard food can help avoid these illnesses even as the climate changes. Climate change will have a variety of impacts that may increase the risk of exposure to chemical contaminants in food. For example, higher sea surface temperatures will lead to higher mercury concentrations in seafood, and increases in extreme weather events will introduce contaminants into the food chain through storm water runoff.
d. Other Health …show more content…

For example, changes in temperature and precipitation, as well as droughts and floods, will affect agricultural yields and production. (USDA, 2015) In some regions of the world, these impacts may compromise food security and threaten human health through malnutrition, the spread of infectious diseases, and food poisoning.

The worst of these effects are projected to occur in developing countries, among vulnerable populations. (IPCC, 2014) Declines in human health in other countries can affect the United States through trade, migration, and immigration and has implications for national security. (CCSP,

advances promoted basic growth in all aspects of life, even forming new industries. 5.

There would be no plant growth, so less oxygen for people, and food for certain animals if the sun was blocked. Short term would be plants deprived of light for growth and food, and long term would be humans and animals being affected greatly from lack of producers. There will be absolutely no growth of any sort for plants or humans because there would be no sunlight to produce anything, therefore everything will go extinct and there will be no living things on earth. The producers will not have any source to grow, the consumers won’t be alive basically because there is no food source and the predators will die because they too won’t have a food source, the decomposers would become food source’s for the new plants because of adaptation and the world will become overfilled with dead bodies, and the

The increase in the heat during the summer is dangerous to communities that lack air conditioning. The heat is starting to threaten the health of Michigan residents and people across the Midwest. In “What Climate Change Means for Michigan”, the EPA states that in recent decades, “severe heat waves have killed hundreds of people across the Midwest” (EPA, 2016). Higher average temperatures results in more cases of heat related health issues such as dehydration, heat stress, and heat stroke. This change in climate is causing many ecological and social changes in the area such as a change in tourism and infrastructure.

Another effect of climate change is ocean acidification. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year. Now, the problem today is that some people, at least those who do not deny the issue of climate change, see climate change as only an environmental issue. However, it is important to realize that climate change is not only an environmental issue, but also a major health issue as it can easily affect a significant number of individuals, especially those in third-world countries. In countries like Bangladesh and the Philippines, the climate restrains the people of the country to grow crops and make food for themselves.

Globalization and Public Health             It is apparent that the flow of people, food, and manufactured goods can have many negative impacts on public health worldwide. The spread of infectious diseases such as the West Nile Virus and H1N1 – better known as the “swine flu” – have shown us that this ease of transport comes with a price. However, it is difficult to say if we should take measures to reduce the exchanges that have brought our world closer and closer together. We have grown so used to having things so connected and available that reducing this would regress the world as we know it.

Global warming can cause many changes in our environment. Polar ice caps can start to melt which can cause rising sea levels and can easily lead to coastal flooding on the eastern seaboard. There can also be affects on the types of storms that can occur if global warming continues. Scientists say that category three storms can turn into a more dangerous category fours. Farms and cities will face new pests, heatwaves, heavy downpours, and increased flooding.
