What You'll Learn
The cost of litter cleanup
Businesses pay the lion's share, contributing around $9.1 billion, or 80% of the total cleanup bill. This, in turn, affects employees and consumers, as businesses may offset these costs by reducing wages or increasing prices. NGOs and educational institutions also bear a substantial burden, with annual costs of $769 million and $240 million, respectively.
The high cost of litter cleanup is not limited to the US. In the UK, the annual cost of removing chewing gum from pavers is estimated to be around £60 million. London's pre-Olympic clean-up campaign in 2012, which included steam-cleaning streets to remove gum, cost up to $3 per wad.
The financial implications of litter go beyond the immediate cleanup costs. Areas plagued by litter experience a decline in tourism and property values, with property values decreasing by around 7%. Heavily littered neighbourhoods also tend to have higher rates of vandalism and crime. The presence of litter negatively impacts the quality of life and sense of safety for residents.

The impact on food security
Land pollution has far-reaching consequences for food security. The contamination of soil with hazardous substances poses risks to human health and food sources. Chemical fertilisers, pesticides, and heavy metals are among the pollutants that can render soil infertile and unsuitable for agriculture. This is particularly concerning given that it can take up to 1,000 years for a few centimetres of arable soil to form.
Agricultural activities are a significant contributor to land pollution. Unsustainable farming practices, such as the overuse of chemical fertilisers and pesticides, and intensive cultivation, can lead to soil erosion and depletion of natural nutrients. This, in turn, reduces land fertility and the availability of food. For example, the excessive use of nitrogen-based fertilisers can lead to an overabundance of plants and algae in lakes and rivers, which reduces oxygen levels in the water and harms aquatic ecosystems.
The impact of land pollution on food security is not limited to localised areas but is a global concern. Pollutants can be transported by air and water, affecting even the most remote regions. Soil degradation, which includes the loss of organic carbon, increased salt content, and acidification, poses a significant threat to food security by reducing the amount and quality of harvests.
The consequences of land pollution on food security are exacerbated by population growth. As the demand for food increases, the pressure on agricultural lands intensifies. This can lead to further degradation of soil and a decrease in food production, potentially triggering a food security crisis.
To mitigate the impact of land pollution on food security, it is essential to adopt sustainable agricultural practices. This includes reducing the use of chemical fertilisers and pesticides, implementing crop rotation, and utilising natural pest management strategies. Additionally, afforestation and reforestation can help control soil erosion, as tree roots hold soil particles together, preventing them from being washed away by rainwater.

The economic impact of soil remediation
Soil pollution has a significant economic impact, and soil remediation plays a crucial role in mitigating these effects. The economic costs of soil pollution include both direct and indirect costs. The direct cost of remediation and management is substantial, with countries spending anywhere from tens of thousands to hundreds of millions of dollars annually. The cost varies depending on the site characteristics, such as the size of the affected area, the concentration of contaminants, and the chosen remediation technology.
The indirect costs of soil pollution are often overlooked but can lead to a significant underestimation of its impacts. Soil pollution reduces crop yields, contaminates food crops, and decreases water quality. It is estimated to cause annual agricultural economic losses worth billions of dollars due to lost productivity and food contamination. Additionally, soil pollution threatens soil biodiversity, causing disruptions to communities and reducing the resilience of ecosystems.
Traditional soil remediation techniques, such as physical and chemical remediation, have several negative impacts on the environment, including changes in edaphic conditions, generation of toxic byproducts, accelerated soil erosion, and economic non-viability. On the other hand, emerging techniques like phytoremediation offer a more environmentally friendly and cost-effective approach, saving about 60-80% of the cost associated with traditional methods.
Overall, the economic impact of soil remediation can be substantial, but it is a necessary investment to mitigate the far-reaching consequences of soil pollution on the environment, human health, and the economy. By restoring soil health, we can help secure the future food supply, reduce water stress, and mitigate climate change, ultimately contributing to sustainable development and a healthier planet.

The effect on industrial productivity
Land pollution has far-reaching consequences for industrial productivity. The contamination of soil and land surfaces, often caused by unsustainable agricultural practices, improper waste disposal, mining, and construction, poses significant challenges for industries that rely on these natural resources.
One of the primary ways land pollution affects industrial productivity is by diminishing the availability of fertile land for agriculture. The use of chemical fertilizers, pesticides, and intensive farming practices can lead to soil erosion, depletion of nutrients, and contamination. This results in reduced crop yields and impacts industries dependent on agricultural produce, such as food processing, textiles, and biofuels.
Additionally, land pollution disrupts natural ecosystems and contributes to biodiversity loss. This has indirect effects on industries such as tourism, eco-friendly product manufacturing, and certain sectors of biotechnology. For example, the decline in bee populations due to habitat destruction and contamination of flora can impact industries reliant on bee-mediated pollination, such as fruit farming and honey production.
The contamination of soil and groundwater with toxic chemicals and heavy metals is another consequence of land pollution. This can affect industries that rely on clean water sources, such as food and beverage production, agriculture, and certain manufacturing processes. Industries may need to invest in additional water treatment processes or face production disruptions due to water scarcity, increasing operational costs and reducing productivity.
Moreover, land pollution contributes to climate change, with polluted areas becoming dry and susceptible to wildfires. The impact of climate change on industrial productivity is vast, including disruptions to supply chains, increased production costs due to extreme weather events, and reduced availability of natural resources. Industries such as agriculture, fishing, and forestry are particularly vulnerable to the effects of climate change.
Lastly, land pollution can lead to increased air pollution, especially in areas with open burning of waste. This can create respiratory issues among workers, reducing productivity and increasing healthcare costs for industries.

The cost of healthcare
Land pollution has a significant impact on the cost of healthcare, placing a substantial burden on the economy. The healthcare sector is responsible for a notable proportion of emissions, contributing to air, water, and soil pollution. These emissions have direct and indirect effects on public health, leading to increased healthcare costs.
The US healthcare sector, for instance, is highly interconnected with industrial activities, resulting in substantial pollution. A study by Eckelman and Sherman (2016) estimated that the environmental and public health impacts of the healthcare sector in 2013 were significant. The sector was responsible for approximately 9% of national greenhouse gas emissions, with hospitals being the second-most energy-intensive commercial buildings in the country. The economic input-output life cycle assessment (EIOLCA) model was used to estimate the emissions and their subsequent impact on public health. The study found that the healthcare sector caused around 470,000 disability-adjusted life-years (DALYs) lost due to pollution-related diseases, which is comparable to the number of deaths caused by preventable medical errors in hospitals.
Furthermore, the healthcare sector's pollution contributes to fine particulate matter in the air, which is the leading cause of air pollution-related diseases. According to the World Health Organization (WHO), 87% of the global population lives in areas exceeding the recommended Air Quality Guideline for fine particulate matter. This has significant health implications and increases the demand for healthcare services.
Additionally, land pollution from agricultural practices can also have indirect effects on healthcare costs. The use of pesticides, fertilizers, and livestock grazing can contaminate water sources, leading to increased treatment costs. For example, the presence of nitrates and algal blooms in drinking water can significantly increase treatment expenses, as seen in Minnesota.
Moreover, land pollution can lead to the spread of vector-borne diseases. Changes in land use, such as agricultural activities or urban development, can influence the transmission of vector-borne diseases. This, in turn, can result in increased healthcare costs for both individuals and the economy as a whole.
Overall, the impact of land pollution on the cost of healthcare is significant. The interconnectedness of the healthcare sector with polluting industries, the contribution of healthcare facilities to emissions, and the indirect effects of agricultural and land use practices all drive up healthcare costs. Addressing these issues through waste reduction, energy efficiency, and sustainable practices can help reduce the economic burden of healthcare while also improving public health outcomes.
