When someone talks about clean energy, nuclear energy is usually not the first choice. Instead, people would go for sources such as solar and wind. However, there is a reasonable call for the inclusion of nuclear energy as a sustainable source. As a matter of fact, nuclear is the second-largest source of low carbon electricity after hydroelectric power. Still, there are some environmental impacts of nuclear energy. We have identified five reasons for and five reasons against nuclear energy as an environmentally friendly energy source.

Why is nuclear energy an environmentally friendly energy source?

1. It protects air quality.

Nuclear energy is a clean energy source with a 100% zero-emission.  It produces energy via fission, whereby uranium atoms are split to produce electricity.  In return, the heat generated is used for purposes of making steam. The steam is then used for spinning turbines hence generating electrical power.

The entire process of generating nuclear energy doesn’t entail using harmful byproducts such as those emitted by major fossil fuels.  Nuclear energy doesn’t emit carbon emissions. It helps with maintaining clean air by eliminating harmful air pollutants from the atmosphere.  Such contaminants are responsible for smog and acid rain, not to mention the adverse implications they have on the overall air quality. They further cause diseases such as cardiovascular disease and lung cancer.  

2. It produces minimal waste.

Nuclear fuel is way denser than other conventional energy sources such as coal. While nuclear fuel is known for producing nuclear waste, the waste is rather minimal. Furthermore, nuclear waste can be easily recycled and reprocessed. For that reason, nuclear energy is widely perceived to be part of a clean energy solution. In some nations like the US, nuclear scientists are developing advanced reactor designs that will operate using used nuclear waste. This development will make nuclear energy highly renewable in comparison to other energy sources. Also, there is a global effort to make nuclear power a clean energy solution in the future, considering that other energy sources face possible extinctions due to rising global populations.

3. It has a relatively small land footprint.

Nuclear energy produces vast amounts of clean energy. It further provides more electrical power on less land more than other clean energy sources. For instance, a nuclear facility producing about 1,000 megawatts requires just 1 square mile of land to operate effectively. This productivity is contrary to wind energy, whereby wind farms require vast areas to produce a similar amount of electrical power. Solar plants also need 75 times more land space to generate a similar amount of energy to nuclear energy. In other words, approximately 4 million solar panels are required to produce 1,000 megawatts. Also, 430 wind turbines are needed to create a similar amount of electricity. The fact that nuclear energy boasts the smallest footprints of all the traditional energy sources makes its environment friendly to a more considerable extent.  

4. Nuclear energy produces less radiation.

Unlike coal, alongside other fossil fuels, nuclear power produces less radiation. Primary energy sources are considered environmentally unfriendly, given the vast amount of radiation they release into the environment. For instance, coal releases the biggest amount of radiation than any other energy source. Burning coal releases a vast volume of thorium and radioactive elements into the environment. Such elements are potentially disastrous to the environment. Apart from radiation, the risk of nuclear energy contaminating the air is significantly low. Today’s nuclear plants have sophisticated security and safety features, hence preventing nuclear accidents and causing widespread air pollution alongside other serious environmental concerns.

5. It reduces overreliance on fossil fuels.

Nuclear energy eliminates the over-reliance on fossil fuels, ultimately making it exceptionally environmentally friendly. Its usage discourages the continued exploitation of the few remaining fossil fuel reserves.  The over-reliance on fossil fuels causes multiple environmental hazards. For instance, the burning of these fuels increases carbon emissions, consequently exposing the world to climate change and global warming. The pollution caused in the process of burning fossil fuels contaminates the atmosphere, further affecting air quality. 

Why nuclear energy isn't an environmentally friendly energy source

1. Environmentally harmful nuclear waste

Although nuclear energy is associated with zero carbon emissions and minimal waste, the resulting nuclear waste can pollute the environment if disposed of inappropriately.  For instance, when this waste is buried in the soil, the chemicals can diminish soil quality, eventually maiming plant species. Once disposed in oceans alongside other water bodies, it leads to thermal water pollution. Long-term thermal water pollution contaminates water and kills marine life.  The process of generating nuclear energy, which entails mining of uranium, is highly hazardous to the environment. Besides, it places human life at risk as miners are exposed to possible mine collapses. 

2. The entire process of harnessing nuclear power isn’t environmentally friendly at all.

Nuclear energy may be perceived as clean and renewable.  However, nuclear power plants impact the environment negatively. The process of mining and enriching uranium isn’t environmentally friendly as such. Mining uranium leaves the soil with huge pits, which causes erosion in return. The radioactive particles left behind in the process of mining uranium pollute the soil and nearby water sources. Again, underground mining exposes the atmosphere to vast amounts of radiation, which causes ailments such as skin cancer.

3. Nuclear accidents are disastrous

While accidents at nuclear facilities are minimal, they can be fatal when they happen. The radiations resulting from accidents are harmful to the environment. They lead to the loss of human life and animal species once they contaminate the environment. The plutonium released into the atmosphere in the events of accidents can expose humans to multiple types of cancer, including bone, lung, and liver cancer. The byproducts of nuclear fuel can further ruin plant species upon encountering the soil. Accidents at nuclear facilities are safety concerns for the environment, animals, humans, and plants.

4. Nuclear waste takes years to decompose.

Perhaps the most significant environmental concern raised by nuclear energy is nuclear waste. Even when it is properly disposed of, nuclear energy takes so many years to decompose. For this particular reason, nuclear power becomes an environmental and safety concern. Before the nuclear waste decomposes to the appropriate safety levels, it can pose serious environmental concerns. For instance, it can continue releasing radioactive radiations, which can affect and even kill animal species.

Again, it can contaminate the soil adversely affecting its quality. Worse still, undecomposed nuclear waste can contaminate water sources making the water unfit for both animal and human consumption. Furthermore, contaminated water as a result of nuclear waste can suppress and kill marine species if it drains in rivers, lakes, or oceans. Most importantly, nuclear waste can continue emitting pollutants into the atmosphere before it decomposes fully. This pollution ruins air quality and causes ailments as well.

5. Nuclear energy may be unfair to poor countries

Establishing a nuclear plant is an expensive affair. As such, it may result in poor countries relying on rich countries in fulfilling their energy requirements.

Worse still, the poor countries may decide to build nuclear plants anyway. Of course, they may not follow all the necessary protocols. As a result, the plants may be unsafe for humans and the environment.

A more political concern is the proliferation of nuclear weapons. It is a short leap from producing nuclear energy to nuclear weapons.

Is nuclear energy good or bad for the environment?

This billion-dollar question is hard to answer. For sure, the world’s energy demands are increasing every day. On the one hand, nuclear energy is a solution. For it can produce massive amounts of energy from ‘fewer’ natural resources hence minimal environmental impacts. On the other hand, the production of nuclear energy leads to the production of toxic pollutants that have adverse effects on biodiversity. You be the judge of whether nuclear is an environmentally friendly energy source or not.

Over the previous decades, research has been focused on understanding the relationship between man and nature. While pundits may argue about this relationship, there is substantive evidence demonstrating an intricate relationship between humans and nature. We depend on nature for basic needs, economic growth, and health. 

Man lives in the sphere of nature. 

As humans, nature always surrounds us.  We interact with it now and then. The biosphere is the most crucial part of nature regarding the man-nature relationship. It includes the thin layer surrounding the earth, the soil cover, and any living creature.  Without nature, human beings can’t live normal lives. In other words, man needs nature more than nature needs him. Nature can exist without man, but humans can’t exist without nature.

Man has a massive influence on nature

Humans aren’t just mere dwellers in the sphere of nature. They also transform nature.  Since man’s existence, he has adapted nature and further made all sorts of incursions into nature. Man has spent enormous energy and time changing nature.  The observation explains that man has consistently transformed nature’s wealth into the present-day means of the historical and cultural life of modern society.  For instance, man has exploited nature to generate electricity and then utilizes the electrical power to serve his interest and his community.  Man hasn’t just transferred a variety of animal and plant species to various climatic conditions, but he has further altered the climate of his habitat.

Man and nature connection is strong.

While man’s connection to nature has been severely weakened by man’s dependence on nature for domestic and industrial resources over the years, man still has a strong connection to nature.  After all, man’s psychological and physical need for nature remains intact. As far as nature will continue being man’s source of physical and psychological well-being, humans will remain deeply connected to nature. That explains the deep and strong relationship between nature and man.

Nature and man interact dialectically.

The interaction between nature and man is such that, the more the society progresses, the more man relies less on nature. Think about it; we rely on natural resources for the sustenance of cities and the development of technologies. The components of your phone are mainly derived from the minerals-a natural resource! Again, as man continues to discover more about nature, the more he strives to transform it. Man’s influence on nature increases progressively. Nevertheless, man continues to come into more contact with nature as time progresses.

There are specific stages of man-nature relationship.

The relationship between nature and man has various stages. The first stage is whereby man depends entirely on nature.  Since time immemorial, man has thrived regardless of the enormity of natural formations. He has always been awake to nature’s destructive and menacing forces. The second stage of the man-nature relationship is whereby nature changes its face in the course of its interaction with man. The third stage is whereby man is concerned with preserving nature for the sake of his needs.

The man-nature connection has led to unforeseen paradoxes

One of the unforeseen paradoxes that have been brought about by the man-nature relationship is the infamous paradox of saturation. Since the existence of man on the planet millions of years ago, the effects of humans’ power over nature were insignificant.  With time, man’s over-exploitation led to the destruction of nearly all aspects of nature. A key example of the prolonged over-exploitation of nature by humans is pollution.  Over the years, pollution has led to the destruction of key aspects of nature such as water and the atmosphere. Currently, plastic pollution is an environmental menace that is challenging for our generation. 

The man-nature relationship has been characterized by overuse and imbalance.

Almost every part of man’s history has been marked with nature exploitation, specifically environmental degradation.  Initially, humans were incredibly in-tune with their surroundings. The ancient people had an insignificant effect on nature, due to their meager population size. But as the human population continued to soar, coupled with technological advancements, man started using more efficient methods of sustaining himself. As populations grew, and societies evolved, the demand for resources shot drastically. This trend led to man distancing himself from nature. He was no longer in-tune with nature. This led to an imbalance and over-use of nature.

The industrialization has alienated man from nature

Whereas no one would deny that man has depended entirely on nature for virtually all his needs, industrialization has taken a toll on nature.  With the rise of industrialization, man is gradually being alienated from nature.  But due to man’s understanding that he is completely dependent on nature, there have been concerted attempts in the world over to redeem man’s connection to nature. It is no wonder that concepts such as Environmental Impact Assessments are becoming more relevant.

Nature always fights back, and wins

Generally, humans have an insatiable appetite for exploiting nature. We tend to overuse the natural resources by our excessive consumption. There are many ways in which nature has fought. Two of the ways are highlighted below:

  • Climate change: Our overuse of fossil fuels is leading to climate change that is having devastating impacts on our lives. The effects of climate change range from sea level rise to adverse weather conditions
  • Disease outbreaks: As humans destroy and come in close contact with natural habitats, we are further exposed to the numerous pathogens. It is suspected that the corona virus is a zoonotic disease. The more we encroach into natural habitats, the more we will expose ourselves to diseases

Man is a vital part of nature

Man defines nature as much as he is fully dependent on it. Historically, man has a considerable influence on nature. Through his actions, whether unconscious or conscious, man determines which course nature will take.  In other words, man determines the pace that nature will take to evolve. As such, nature and man are inseparable. Man depends on nature for all resources he requires in life. He, therefore, should remain in-tune with nature since he is an integral part of it.

The man-nature connection is sometimes ‘unclear’

The connection between man and nature is, at times, ambiguous, as much as it is intricate. For instance, nature can be an enemy to man as much as it remains a provider. Think about environmental disasters such as earthquakes, typhoons, and floods. On the other hand, man is the main beneficiary as far as the relationship is concerned. Since time immemorial, man has always strived to dominate nature. Nevertheless, this domination is currently being revised by societies in the world over. For instance, we are learning that dominating nature is difficult, as exemplified by the complexities of climate change.

Conclusion

The man-nature relationship has had its ups and downs since time immemorial. Although the connection is intricate, multiple instances prove that the present-day man isn’t in-tune with nature. As such, humans must consider their relationship with nature, considering that they need nature more than nature needs them. There should be a universal awareness of how humans can best use nature without exploiting it so that the man-nature connection can continue to thrive.
