Examining Human Impacts

Examining Human Impacts

The effects of climate change are becoming increasingly evident in our daily lives, yet it can be difficult to connect the dots to determine how exactly we’ve contributed to global climate change. As individuals, our actions are a significant contributing factor when it comes to global warming and the detrimental long-term effects that the planet is facing.

In order to take action and curb the effects of climate change, understanding why and how our actions contribute to the problem is essential. To be able to actively make changes, it’s crucial to know how our individual behaviors and collective ones as a society impact climate change.

Examining Human Impacts

The Role of Greenhouse Gases

One of the primary causes of global warming is the emission of gases such as carbon dioxide and methane that trap heat in the environment. These gases are called “greenhouse gases,” and their accumulation in the atmosphere is a result of human activities.

Fossil fuels are burned to create power, and transportation is powered by them as well. Animals are farmed and factories emit smoke, both of which create a large amount of greenhouse gases. The burning of fossil fuels and other combustion processes create greenhouse gases that trap heat, which is a major factor of global warming.

Deforestation and Agricultural Practices

A considerable amount of trees are lost each year due to deforestation, which has devastating consequences. Trees act as natural carbon sinks, as they absorb huge amount of carbon dioxide from the atmosphere. When these trees are cut down or burned, the absorbed carbon dioxide is released back into the atmosphere. This makes it very difficult for nature to continue to remove greenhouse gases from the environment in the way it once did.

Agricultural practices can also be an issue. Fertilizers are used to increase crop yields, with nitrous oxide being the most common. Nitrous oxide is another one of the harmful greenhouse gases that contributes to global warming.


Urbanization and cities can also contribute to climate change. The development of cities and urban sprawl often destroys ecosystems, which can indirectly cause an increase in global warming. When these natural spaces are destroyed, their ability to absorb carbon and act as carbon sinks is reduced, resulting in an increase of carbon in the atmosphere.

The energy consumption in cities is also much higher than in other areas. This contributes to the accumulative amount of emissions as they’re released into the environment. The transportation associated with cities requires more fossil fuels, which creates more greenhouse gases, further contributing to the global warming.

Water Pollution and Abuses

The pollution of water bodies is another significant problem. Water pollution happens when pollutants enter the water bodies, affecting the environment. Pollutants such as heavy metals and other chemicals can be released directly into water bodies, while others may enter through runoff.

Water pollution affects the environment by destroying species and damaging ecosystems. The buildup of pollutants in water bodies increases the water temperature, leading to thermal pollution. This affects the biodiversity as the environment becomes too warm for certain species, leading to their death.

Water abuse is also a major contributor to global warming. We put an increasing amount of pressure on our water supply, depleting and polluting it. Water is essential for maintaining our environment, but when we take too much, it can disrupt delicate ecosystems. This can ultimately lead to an increase in global warming.

In understanding how human actions contribute to climate change, we can see the importance of making changes to our behavior and habits. We have an opportunity to make a difference by reducing our individual emissions, and we can also influence others to do the same.

The magnitude of the effects of climate change may be daunting, but we still have the power to take action and help protect our planet. By reducing our own emissions and creating sustainable lifestyles, we can make a lasting impact. It’s never too late to make a difference; we just need to start somewhere.
