The environmental consequences of tobacco

The tobacco epidemic stands as one of the most significant public health challenges the world is confronting. Annually, tobacco claims the lives of over 8m individuals, with approximately 1.2m of these fatalities attributed to second-hand smoke exposure.

In the haze of discussions surrounding the health risks of tobacco use, the environmental toll of this pervasive habit often goes unnoticed. As the global population grapples with the consequences of tobacco consumption, a shadow looms over the very Earth we inhabit. This article seeks to unveil the intricate web of environmental challenges woven by the tobacco industry and its implications for our planet.

The tobacco production cycle exhibits a notably destructive impact. From cultivation and manufacturing to consumption, tobacco inflicts widespread environmental degradation and health hazards. 

Deforestation and agriculture

One of the least acknowledged impacts of tobacco use lies in the vast swathes of land cleared for cultivation. Each year, around 600m trees are felled to produce 6trn cigarettes. Approximately five percent of the annual global deforestation is attributed to tobacco farming. This deforestation significantly amplifies carbon dioxide emissions in the environment, contributing to adverse climate change impacts. Deforestation to make way for tobacco crops eradicates biodiversity and disrupts delicate ecosystems. The use of chemical fertilizers and pesticides further compounds the environmental toll, leaving a lasting mark on the lands where tobacco takes root. The cultivation of tobacco plants necessitates substantial quantities of chemicals, many of which prove detrimental to the environment and farmers' health. This exposure to harmful substances can lead to various illnesses, such as respiratory problems, skin disorders and neurological issues among those involved in tobacco farming.

Water scarcity and pollution

The cultivation of tobacco places an extraordinary burden on water resources, intensifying water scarcity in regions where it thrives. Annually, approximately 22bn tonnes of water is utilized in global tobacco production. Notably, tobacco production demands up to eight times more water than cultivating tomatoes or potatoes. The runoff of pesticides from these tobacco fields presents a substantial risk to nearby water sources, endangering aquatic ecosystems and the well-being of both the environment and local communities.

Cigarette butts, the most visible remnants of tobacco use, are a significant source of environmental pollution. Slow to decompose and laden with toxic chemicals, they pose a threat to soil and water, leaving a long-lasting imprint on the environment. Cigarette butts contain hazardous substances such as arsenic, lead, nicotine and ethyl phenol. When these butts are discarded, these substances leach into aquatic environments and soil. While the precise environmental impact of this waste remains unquantified, the substantial volume of discarded butts raises concerns about potential leachates affecting the quality of drinking water.

A cloud of environmental cost

The journey from farm to cigarette involves energy-intensive processes and the consumption of vast resources. The paper production for cigarette packaging, often derived from deforested areas, contributes to environmental degradation. The weight of non-biodegradable packaging waste adds to the already substantial burden on the planet. They contribute to an annual production of 767,000 kg of toxic waste, while 4.5trn cigarettes scatter across our cities, parks, beaches and waterways, contaminating both land and water.

Stubbing out the planet’s health

Beyond the ecological toll of deforestation and manufacturing, the plastic pollution from tobacco wrappers exacerbates urban environmental challenges. Discarded wrappers clog drains, pile up on th streets and contribute to the global plastic crisis. Cities face blockages and increased municipal waste management challenges, further emphasizing the need for sustainable alternatives. Moreover, discarded cigarette butts stand out as the most prevalent type of plastic waste globally.

Smokeless tobacco products are usually wrapped in a plastic packet, which poses an environmental impact. In Nepal, usually during the rainy days, major cities face a similar kind of drainage blockage resulting in flooding and disrupting daily activities. 

Air pollution 

During the intricate process of curing tobacco leaves, a cascade of harmful chemicals is released into the air, becoming a significant contributor to air pollution in regions dominated by tobacco cultivation. This airborne pollution transcends the boundaries of the tobacco fields, casting a shadow over communities and posing a direct threat to the health and overall well-being of the people residing in these areas.

Tobacco cultivation contributes to air pollution. Additionally, the act of smoking cigarettes itself significantly impacts air quality. Combusting cigarettes releases over 7,000 chemicals, with at least 69 known to be carcinogenic and many possessing poisonous properties.

A study conducted in Italy revealed that cigarettes emit particulate matter into the air at a rate 10 times higher than that of a diesel engine. The combined emissions from cigarette smoke and tobacco cultivation directly contribute to climate change.

The hazards of secondhand smoke are widely recognized, emphasizing the importance of considering it not only as a public health concern but also as an environmental issue.

Global impact and social responsibility

The link between the tobacco industry and environmental degradation cannot be ignored. As consumers, it is imperative that we consider the environmental consequences of our choices. Advocacy for corporate responsibility and sustainable practices within the tobacco industry is crucial for mitigating its global impact.

Tobacco is cultivated in 125 countries, involving around 33m farmers, often receiving direct support from tobacco companies. This labor-intensive, low-yield crop demands substantial pesticide use. According to UNICEF, if the land were utilized for food production instead, it could potentially benefit 20m hungry people.

Beyond the smoke rings

In the quest for a healthier world, we must not only address the health risks associated with tobacco use but also confront the environmental consequences. It is time to unmask the hidden toll of tobacco on our planet and collectively work towards a more sustainable and responsible future. The most impactful strategy is to cease smoking altogether and, concurrently, to launch awareness campaigns discouraging the initiation of smoking.

Unveiling the concealed toll that the tobacco industry exacts on our planet, it is incumbent upon us to collaboratively forge a more sustainable and responsible future. Governments, through measures such as environmental taxes on cigarettes, can play a pivotal role, as evidenced by the positive step of enacting an environmental tax as  taken by nations like Benin, Chad and Gambia. Such proactive measures not only serve to discourage the consumption of environmentally harmful products like cigarettes but also contribute to revenue generation for the government. The imposition of environmental taxes aligns with broader global efforts to address public health concerns and mitigate the impact of climate change. By adopting such policies, governments demonstrate their commitment to creating a sustainable and healthier future for their citizens.

The recent initiatives taken by local authorities in Nepal, particularly by the Kathmandu Metropolitan City, to ban plastic-wrapped tobacco products are commendable beginnings. Nevertheless, the Supreme Court has issued a verdict to halt its implementation until the court takes a final decision. The government has the opportunity to take further steps by introducing environmental taxes on tobacco products, prohibiting the use of plastic wrappers and facilitating the transition of tobacco farms to cultivate alternative crops.

At an individual level, supporting policies banning single-use plastics, encompassing cigarette filters, smokeless tobacco pouches and disposable electronic cigarettes takes us toward a cleaner, healthier planet. In dismantling the smoke rings that shroud the environmental impact of tobacco, we embark on a collective journey toward a sustainable and responsible future.
