Sample Environmental Studies Paper on Impacts of climatic change on our health

In the current era, people across the globe have put their focus and attention on facing climate change. Climate change stands out as the major worldwide challenge today, making the world more and more vulnerable to the changes. This can be seen via newspapers, broadcasts and various social sites.  Climate change can be defined as a long term alteration of average temperature, rainfall and other weather patterns and conditions in a given place. The change can be in specific regions or global. Climate changes are caused by various factors such as fossil fuels and other human activities such as cutting down of trees, burning fossil fuels and agriculture. Increased temperatures brings about warming in the oceans bringing about change in weather patterns which affects people in both rural and urban environments. Climatic changes brings about various negative effects on human health, thus some strategies ought to be implemented in order to curb/ minimize the intensity of the effects.

Climate change leads to different potential impacts on human life.  For instance, a global increase in average temperatures brings about a rise in the sea level. According to (Niamh et al 12), the increased temperatures and melting of arctic sea ice poses a threat of flooding to low laying areas. Nowadays, a big percentage of cities are situated at low laying coastal regions. As a result, the rise in sea level brings coastal properties at risk of destruction. Since human race is highly dependent on plants and animals for food, the melting ice affects human activities especially commercial transportation and food supply in the surrounding areas. Many regions are requesting for rights in arctic shipping lanes when the ice melting occurs so as enable them run their commercial activities. Thus, Sea water temperatures and the flow of ocean currents affects worldwide weather patterns and human life.

Arctic sea areas serves as a home for different animals. Thus, arctic sea melting brings about a threat to their lives and survival. Water animals that rely on the ice plays a significant role for humans. For instance, the seals use arctic ice for breeding as the polar bears depend on the ice for hunting and relaxing. The melting of the ice exposes these species into danger and without a shelter. This may later result into a significant reduction in their population as they are exposed to various threats. Many people depend on the sea animals for food. Therefore, the reduced population of the arctic animals, will result into a reduction of food for people who depend on them thus, affecting the general human life.

Climate change also has the ability to affect energy demand. Climatic changes with high temperatures and increased wind speed, is more likely to affect energy consumption. Energy demand, holds both positive and negatives impacts on human existence. Presence of safe, affordable, and clean energy is beneficial to humans. On the other hand, energy mining, transportation and use can hold negative effects to health and economy of a region. More energy is demanded for fossil fuels resulting to an increase in greenhouse gas emissions. The gas emissions can cause significant harm to human life if not well mitigated.

Climate change also has a negative impact on human health. This is as a result of a reduced quality of fresh air human’s breath. Increased heat results in to air pollution. As the weather gets warmer, there is a rapid formation of smog (ground level ozone) and increased ultraviolet radiation. Smog is formed as a result of a reactions between sunlight and burning fossils Also, climate change contributes to formation of allergenic air pollutants such as molds and pollen.  The small elements of gas/ solids emitted from the pollutions are harmful to human health once inhaled. This is because they have the potential to penetrate the lungs and blood stream of the human body, resulting heart attacks or even death.

Also, the climatic changes affects the aquatic surroundings and proceeding the effects to humans, for instance, via the spread of water-borne diseases like cholera. As the temperature rises, the climate becomes more and more unpredictable, paving a way for cholera outbreak. The spread of cholera is greatly fueled by high water temperatures, salinity and low precipitation. High temperatures, leads to increased rates of water vaporization, resulting to lower water levels in rivers. The lower the water levels, the lower the levels of salinity thus, providing a good environment for bacteria’s to replicate. The outbreak of cholera results to death of people, affecting the general human life.

Various strategies and actions needs to be put in place, in order to curb and reduce the degree at which climate change affects human population. The WHO predicts that annual 250,000 deaths from 2030 will be as a result of climate change, (Andy and Kristie, 273). Thereby, some of the measures needs to be put in place to reduce the chances of such deaths from happening. Some of the measures include,  include, forgoing fossil fuels, upgrading the infrastructure, planting trees, unplugging, instituting transportation means with less emissions, enhancing less energy consumption, and finally adoption of organic farming.

Combustion of fossil fuels is among the primary contributors of climate change across the globe. Fossils emit large amounts of carbon dioxide when burnt. The carbon thereby holds heat in the air resulting to climate change. To reduce the effects of fossil fuels on the climate, people need to adopt measures that facilitate the use of renewable energies, rather than fully relying on oil, gas etc.  Actions of enriching people on the importance of feeding natural foods/ vegetables, rather than fossilized ones can help reduce the negative impacts. More alternatives should be provided and investments on carbon capture and storage implemented.

Secondly, investing and upgrading the infrastructure systems, like good roads can help combat the intensity of the effects. A sustainable infrastructure can help improve air quality by reducing the emissions from vehicles. The use of good infrastructure system, improvement of existing highways, well organized water systems and renewable energies, can influence in reducing greenhouse gas emissions released in the atmosphere. Another viable strategy is to educate people globally on the importance of planting trees and stop deforestation. Cutting down trees contributes a very high percentage of harmful gas emissions in the atmosphere. This is as a result of oils used by the machineries during the activity and as the tress release the carbon they had stored. After cutting down the trees, burning them creates a space for more emissions affecting the human health.

Unplugging gadgets from their power rather than switching off can help reduce emissions. Buying less energy consuming gadgets can boost save money and energy thus reducing greenhouse gas emissions. For instance, the adoption of fast battery chargers can reduce the time consumed during charging, reducing the overall gas emissions. Also replacing old luminescent bulbs with better ones can reduce fluorescents helping save energy.  The incandescent light bulbs contains mercury hence calls for a proper disposal to prevent causing more harm to human body. The lesser the energy consumed, the lower the risks of effects of the climate changes.

 

Conclusion

Climate change causes more negative impacts on human health than positive. Climate change is mainly caused by human activities such as agriculture, deforestation and burning of fossil fuels. This practices emits harmful gases in the atmosphere, bringing the human health at risk and exposure to diseases and calamity. High temperatures results in to death of people and more sufferings to human race. This is because a high percentage most people rely on nature for survival thus lending them dying from floods, drought, heat waves and storms. Also, the changes in climate exposes humans to high risks of diseases such as cholera and malaria. Additionally, high temperatures results to formation of smog, a ground ozone layer that increases mortality rates and heart attacks from the inhaled gases.  Arctic sea ice is very vital to human and animal survival. Many people residing on coastal areas, highly depend on sea ice for hinting thus creating a means to provide food for their families. When the sea ice melts as a result of climate change, the entire ecosystem is affected thus, affecting the whole human life of those that depend on the sea food for survival.

Nevertheless, Implementation of various strategies can help reduce these impacts.  For instance, upgrading the infrastructure system can reduce the amount of fuel consumed by cars thereby reducing the amount of gases emitted in the atmosphere. Also, discouraging deforestation and replacing fossil fuels with other and better alternatives can help reduce the greenhouse gases emitted in the environment thereby combating the risks. Unplugging gadgets and replacing high energy bulbs with better alternatives can also reduce the energy consumption and save more energy. Climate change has a great negative impacts on health, thus possible measures need to be put in place to protect people from suffering.
