Pollution's Impact: Worse Than Second-Hand Smoke

While second-hand smoke is a well-known cause of disease in humans and animals, pollution affects the environment more extensively. Pollution, caused by energy use, production, and industrial processes, releases harmful chemicals and gases into the air, water, and soil. It contributes to climate change, deforestation, and water contamination, with tobacco cultivation being a significant source of environmental issues. The impact of tobacco cultivation includes land and water pollution due to pesticides, air pollution from burning tobacco, and waste from discarded cigarette butts, which are toxic and non-biodegradable. Additionally, the tobacco industry is responsible for massive deforestation, with an estimated 600 million trees cut down annually, contributing to global warming. While second-hand smoke is detrimental, pollution has a broader reach and poses a more significant threat to the planet.

Pollution affects the air, water, and soil

How Pollution Affects the Air, Water, and Soil

Pollution is a critical issue that significantly impacts the environment, encompassing the air we breathe, the water we rely on, and the soil that sustains life. Understanding its far-reaching effects is crucial in mitigating its consequences and preserving the planet for future generations.

Air Pollution

Air pollution refers to the release of harmful substances into the atmosphere, endangering both human health and the planet. It is primarily caused by energy use and production, such as burning fossil fuels for transportation, heating homes, and powering factories and plants. These activities release pollutants like smog, soot, and greenhouse gases, which have detrimental effects on human health and the environment. According to the World Health Organization (WHO), air pollution is responsible for nearly seven million deaths worldwide each year.

Water Pollution

Water pollution, as defined by the World Health Organization (WHO), is the contamination of water sources to the extent that they become unusable. This means the water is toxic and unsuitable for drinking or essential purposes like agriculture. Water pollution is caused by various factors, including natural processes such as mercury filtering from the Earth's crust, and human activities, such as industry, agriculture, and improper waste disposal. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, plastics, and even radioactive substances. These pollutants pose a significant threat to human health, with the WHO estimating that approximately 2 billion people are forced to drink water contaminated by excrement, exposing them to deadly diseases.

Soil Pollution

Soil pollution, often overlooked, is a critical issue caused primarily by chemical substances produced by human activities. Intensive farming, stock breeding, and industrial processes introduce chemicals, pesticides, fertilisers, and heavy metals into the soil, endangering land biodiversity and human health. Soil pollution has far-reaching consequences, including the contamination of the food chain, reduced harvest quality and quantity, and the spread of antibiotic resistance in pathogens. According to the Global Land Outlook (GLO2), soil pollution is the biggest environmental cause of disease and death worldwide.

The effects of pollution on the air, water, and soil are interconnected and have profound implications for the planet and human civilisation. Addressing these issues requires collective efforts from governments, institutions, communities, and individuals to implement sustainable practices and mitigate the impact of pollution on the environment.

Cigarette butts are a major pollutant, commonly found in landfills, soil, lakes, oceans, and forests

Cigarette butts are a significant source of plastic pollution, as they are made of cellulose acetate. This means that they do not biodegrade and instead slowly leak a chemical cocktail of highly toxic and carcinogenic substances into soils, waterways, lakes, and oceans. A single cigarette butt can contaminate up to 1000 litres of water. This has a devastating effect on marine life, with research showing that certain algae die after being exposed to water containing compounds that are equivalent to two discarded cigarette butts. These algae are at the bottom of the food chain, so all other sea organisms are feeding on them and getting poisoned, all the way up to fish that humans eat regularly.

Cigarette butts are also commonly found in landfills. While they are theoretically biodegradable, it takes almost two years for them to completely vanish, and that is under perfect conditions. In practice, cigarette butts tossed on streets and beaches do not biodegrade. Instead, they break down into smaller pieces of waste that dilute into water or soil.

The tobacco industry is responsible for producing cigarette butts, and they need to be held accountable for their impact on the environment. It is clear that cigarette butts add to the chemical cocktail affecting humans and the environment.

The tobacco industry is a significant contributor to deforestation

Tobacco farmers often clear land by burning it, which contributes to increased greenhouse gas levels and air pollution. The land used for tobacco cultivation is typically abandoned after a few seasons due to soil depletion, further exacerbating the environmental impact. Tobacco farming is also associated with the use of harmful pesticides and fertilizers, which contaminate water sources and harm local wildlife.

The World Health Organization (WHO) has emphasized the need for the tobacco industry to be held accountable for the environmental damage it causes. In its report "Tobacco: Poisoning Our Planet," the WHO highlights the industry's role in widespread deforestation, pollution, and carbon dioxide emissions. The report calls for policymakers to treat cigarette filters as single-use plastics and consider banning them.

The tobacco industry's contribution to deforestation extends beyond the direct clearing of land for cultivation. Tobacco curing, a process used to dry tobacco leaves, also requires a significant amount of firewood, leading to further tree loss. Additionally, the industry's extensive use of paper for packaging cigarettes further exacerbates the problem. Tobacco manufacturers use approximately four miles of paper every hour for wrapping and packaging their products, contributing to the significant consumption of wood resources.

The environmental impact of the tobacco industry goes beyond deforestation. Tobacco cultivation, processing, and transportation contribute to global greenhouse gas emissions, with a carbon footprint equivalent to one-fifth of the commercial airline industry's carbon emissions. The industry's waste products, including cigarette butts, also contribute to plastic pollution, as cigarette filters contain microplastics that end up in oceans and other water bodies.

Second-hand smoke is a cause of disease in both humans and animals

Second-hand smoke is a serious health risk, causing a range of diseases in both humans and animals. It is a known cause of cancer, including lung cancer, even in people who have never smoked. It is also linked to an increased risk of other cancers in adults, such as nasopharyngeal cancer.

The dangers of second-hand smoke exposure are not limited to cancer. It can also cause coronary heart disease, stroke, and adverse reproductive health effects in women, including low birth weight. In children, second-hand smoke exposure is linked to respiratory infections, ear infections, and asthma attacks, with young children being the most affected. It is also a significant risk factor for sudden infant death syndrome (SIDS).

The harmful effects of second-hand smoke extend beyond humans. Animals, especially those that dwell on beaches, such as large turtles, sea cows, and seals, are frequently exposed to cigarette butts and other tobacco waste that wash up on shores. In addition, deforestation caused by the tobacco industry leads to habitat loss for forest-dwelling animals, contributing to the decline of certain species.

The impact of second-hand smoke on both human and animal health is undeniable. With its link to various diseases and the harm it causes to the environment, second-hand smoke is a pressing issue that needs to be addressed to protect the well-being of all living beings.

Pollution from vehicles is a significant issue for air quality

Vehicle emissions have become the dominant source of air pollutants, including carbon monoxide, carbon dioxide, volatile organic compounds, nitrogen oxides, and particulate matter. The increasing severity and duration of traffic congestion have the potential to greatly increase pollutant emissions and degrade air quality, particularly near large roadways. These emissions contribute to the risks of morbidity and mortality for drivers, commuters, and individuals living near roadways.

The ingredients of air pollution from vehicles

Cars, trucks, and buses produce air pollution throughout their life cycle, including pollution emitted during vehicle operation and fuel production. Additional emissions are associated with the refining and distribution of fuels and, to a lesser extent, the manufacturing and disposal or recycling of the vehicle.

The following are the major pollutants from motor vehicles:

• Particulate matter (PM), including soot seen in vehicle exhaust. Fine particles can penetrate deep into the lungs and pose a serious threat to human health.
• Volatile Organic Compounds (VOCs) react with nitrogen oxides to form ground-level ozone, a main ingredient in smog. Ground-level ozone irritates the respiratory system, causing coughing, choking, and reduced lung capacity.
• Nitrogen oxides (NOx) form ground-level ozone and particulate matter. NOx can cause lung irritation and weaken the body's defenses against respiratory infections.
• Carbon monoxide (CO) is a colorless, odorless, and poisonous gas formed by the combustion of fossil fuels. When inhaled, CO blocks oxygen from the brain, heart, and other vital organs.
• Sulfur dioxide (SO2) is created when power plants and motor vehicles burn sulfur-containing fuels, especially diesel and coal. Sulfur dioxide can react in the atmosphere to form fine particles, posing the largest health risk to young children and asthmatics.
• Greenhouse gases, predominantly carbon dioxide, are emitted by motor vehicles and contribute to global climate change.

The effects of air pollution from vehicles

Pollutants from vehicle exhaust can affect more than just the lungs. Tailpipe pollutants pose health risks at every stage of life and can even cause premature death. Climate change, driven by heat-trapping emissions, also affects people's health and the well-being of entire communities. People in low-income communities and communities of color are disproportionately exposed to higher levels of air pollution.

Addressing vehicle pollution

Addressing vehicle pollution is critical for improving air quality and reducing heat-trapping emissions in communities around the country. Zero-emission heavy-duty vehicles are available, and the market for these trucks is beginning to accelerate, but not at the pace needed to adequately address equitable access to clean air. The right policies and investments from governments will accelerate the transition to a zero-emissions transportation system, including setting targets for electric vehicle adoption and developing incentive programs.
