How Do Human Activities Affect Global Warming

The world is currently facing a number of ecological issues and global warming is among one of the most pressing. It is caused by various human activities in this modern and industrial age, leading to the increase in global temperatures due to the release of greenhouse gases. Human activities that impact global warming range from burning fossil fuels for energy, agricultural practices, air conditioning, and even deforestation. The resulting effects of global warming have a profound impact on ecosystems, human health, and the economy.

When it comes to burning fossil fuels, we not only contribute to air pollution, but also add vastly to global warming. Fossil fuels are composed of carbon and other harmful gases that release carbon dioxide while they burn. Carbon dioxide is a greenhouse gas and traps in heat from the sunlight, resulting in global warming. Burning fossil fuels is used for many activities, such as transportation and electricity production. As the demand for energy steadily increases and new technologies are developed, the burning of fossil fuels is also increasing. The World Wildlife Fund found that over 70% of energy-related emissions come from burning fossil fuels, leading to a global average temperature increase of 1.2°C.

Additionally, air conditioning has become quite a popular commodity in many nations. Air conditioners often rely on hydrofluorocarbons to complete their cycles, which are also greenhouse gases. As more and more homeowners obtain air conditioners and businesses run large-scale facilities to cool their buildings, the amount of greenhouse gas being released continues to rise. According to a report by the International Energy Agency, air conditioners were estimated to account for 1.5°C of the projected global warming by 2100.

Agriculture is a major contributor to global warming, and many farming practices can have a large environmental impact if not done correctly. For example, the use of inorganic fertilizers, which produces nitrous oxide, can lead to land and water pollution as well as increase global warming. Other farming practices that can have a negative environmental impact are without changing the use of arable land, grazing animals, and tilling the soil. All these methods can result in the release of various gases like methane and carbon dioxide, leading to global temperature rise. In fact, the Food and Agriculture Organization estimated that agricultural activities contribute to 25% of the global warming.

Lastly, deforestation is one of the leading causes of global warming. Trees absorb carbon dioxide and release oxygen through photosynthesis. However, when the trees are cut down, they can no longer help absorb the carbon dioxide and process it into oxygen. This emits a larger amount of greenhouse gases into the atmosphere, and is estimated to account for 18% of global warming. In addition, when forests are cut down, they are unable to act as water filters, leading to more water pollution.

Human activities can have detrimental effects on global warming, and the effects can be felt from increased temperatures to the extreme weather conditions. It is our responsibility to make necessary changes to reduce global warming and protect the environment. This can be done through the utilization of renewable energy sources, transitioning to organic farming practices, or by planting more trees. If we can all work together and reduce the resulting effects of global warming, we can ensure a more secure and better future.
