Consumption, Pollution, And The Link To Environmental Degradation

Consumption has a significant impact on pollution levels, with the production and consumption of goods and services being a major driver of global resource use and environmental impacts. This is particularly evident in the case of food and drink, housing, mobility, and tourism, which are responsible for a large share of the pressures and impacts caused by consumption. Overconsumption exacerbates climate breakdown and air pollution, depletes natural resources, and contributes to biodiversity loss and soil sealing. The consequences of overconsumption are evident in the Niger Delta, where oil extraction has led to acid rain and health issues, and in Brazil, where deforestation has resulted in soil erosion, loss of biodiversity, and increased CO2 emissions. Addressing overconsumption requires a combination of individual behavioural changes, such as reducing meat consumption and adopting reusable products, and systemic reforms, including degrowth, eco-socialism, and eco-anarchism.

The impact of overconsumption on natural resource extraction and environmental degradation

Overconsumption has a significant impact on natural resource extraction and environmental degradation. It occurs when humans consume more resources than they produce, and it is a major driver of global resource depletion and environmental degradation. The impact of overconsumption is far-reaching, affecting both the environment and human health.

Firstly, overconsumption leads to increased natural resource extraction. As consumption rates outpace the planet's ability to regenerate resources, we are using up finite resources faster than they can be replenished. This includes the extraction of raw materials such as trees, gas, oil, metal ores, water, and fertile land, which are essential for various economic sectors, including manufacturing, agriculture, and energy production. For example, the Amazon rainforest in Brazil has been deforested for logging and cattle farming, leading to soil erosion, loss of biodiversity, and increased CO2 emissions.

Secondly, overconsumption contributes to environmental degradation and pollution. The production and consumption of goods generate direct and indirect environmental pressures, such as global warming, biodiversity degradation, soil sealing, and air and water pollution. For instance, the extraction of oil in the Niger Delta has resulted in the release of harmful chemicals into the air, causing acid rain that corrodes infrastructure and pollutes water sources. Similarly, copper mining and smelting in Peru have led to water shortages and air pollution, with high levels of lead poisoning found in children.

Moreover, overconsumption is closely linked to economic growth and affluence. The wealthiest countries and individuals consume a disproportionately large share of the world's resources. North America and Europe, for example, have the biggest material footprints globally, with the average person in North America consuming nine times more natural resources than the average person in Africa. This inequality in consumption patterns has significant environmental implications, as the environmental impact per capita increases with higher consumption levels.

To address the impact of overconsumption on natural resource extraction and environmental degradation, a multi-faceted approach is necessary. This includes reducing consumption, particularly in high-income countries, transitioning to renewable energy sources, adopting more sustainable production practices, and implementing policies that promote sustainable consumption and reduce pollution. Individual actions, such as reducing meat consumption, using reusable products, and choosing environmentally friendly transportation, can also help mitigate the effects of overconsumption.

The role of international trade in shifting environmental burdens from high-income to low-income countries

International trade has been a key driver of economic growth and development for many countries, particularly those in Asia and Latin America. However, the process of trade liberalization, which involves reducing trade barriers and increasing market access, has also led to a shift in environmental burdens from high-income to low-income countries. This phenomenon, known as environmental burden shifting, occurs when high-income countries dissociate consumption from production by importing goods produced in low-income countries, thereby exporting the environmental impacts associated with production.

The pollution-haven hypothesis suggests that international trade allows richer countries to shift their pollution and environmental degradation to poorer countries. While there is only partial evidence to support this hypothesis, it is clear that trade liberalization has led to an increase in footprint exports from low-income countries without a corresponding increase in footprint imports by high-income countries. This indicates that low-income countries are bearing a disproportionate share of the environmental burdens associated with production.

Domestic institutions and policies in both high-income and low-income countries play a significant role in shaping the distribution of environmental burdens. For example, political incentives inherent to democratic institutions in high-income countries may encourage environmental burden shifting by prioritizing economic growth over environmental protection. On the other hand, sound domestic policies and institutions in low-income countries can help to partially curb the negative impacts of climate change. For instance, countries with lower public debt and flexible exchange rates tend to experience smaller output losses from temperature shocks.

To address the issue of environmental burden shifting, it is crucial to consider the role of international environmental agreements and preferential trade agreements (PTAs). While the inclusion of environmental clauses in PTAs may not directly influence the distribution of environmental burdens, the design characteristics of these agreements can have an impact. Additionally, the participation of countries in international environmental agreements can help mitigate the negative consequences of trade liberalization on the environment.

Furthermore, the transition to a circular economy, where production and consumption systems are regenerative and restorative, is essential to reducing environmental impacts. This involves promoting sustainable consumption patterns, such as shifting from private car use to collective transport and choosing eco-labelled products. By addressing the root causes of pollution and environmental degradation, such as the dominant "take, make, waste" linear economy, we can alleviate the burden on low-income countries and work towards a more sustainable future for all.

The health risks of air pollution, including premature deaths and cardiovascular disease

Consumption is a major driver of environmental impacts, including air pollution, which poses significant health risks. Air pollution is one of the greatest environmental risks to child health, and it affects people of all ages, causing an estimated 6.7 million premature deaths annually worldwide.

Outdoor air pollution, in particular, is a major environmental health problem, causing approximately 4.2 million premature deaths per year as of 2019. This mortality is due to exposure to fine particulate matter, which causes cardiovascular and respiratory disease, as well as cancers. The majority (68%) of these premature deaths are attributed to ischaemic heart disease and stroke, with the remaining attributed to chronic obstructive pulmonary disease, acute lower respiratory infections, and lung cancers.

People living in low- and middle-income countries are disproportionately affected by outdoor air pollution, with 89% of premature deaths occurring in these areas, particularly in the WHO South-East Asia and Western Pacific Regions. However, air pollution is a global issue, and even in high-income countries, it poses a significant risk to public health.

Air pollution can exacerbate existing cardiovascular disease and contribute to the development of this disease. Fine particulate matter, with diameters less than 2.5 µm (PM2.5), has been found to increase the risk of cardiovascular events. Exposure to increased concentrations of PM2.5 over a short period of time can trigger cardiovascular disease-related heart attacks and death. Longer-term exposure can lead to an increased risk of cardiovascular mortality and decreased life expectancy.

Overall, consumption patterns, particularly in the areas of food and drink, housing, mobility, and tourism, contribute significantly to environmental impacts, including air pollution. This, in turn, poses serious health risks, including premature deaths and cardiovascular disease.

The impact of intensive farming on wildlife loss, soil and water pollution, and animal welfare

Intensive farming has been linked to wildlife loss, soil and water pollution, and poor animal welfare. The world's richest countries consume, on average, ten times as many materials as the poorest, and North America and Europe have the biggest material footprints on the planet. This overconsumption worsens climate breakdown and increases air pollution.

Wildlife Loss

The agricultural industry's demand for more land is a key driver of habitat destruction and degradation. The Earth loses about 18.7 million acres of forests per year, and about 80% of the world's plants and animals live in forests, losing their habitats to deforestation. This puts species under the threat of extinction.

Soil and Water Pollution

Pesticides and fertilisers used on crops fed to animals are a major contributor to land and water pollution. A portion of the fertiliser washes into waterways, along with eroded sediments, and this can lead to the creation of dead zones that kill aquatic life. The use of artificial fertilisers in place of manure can deplete soils, making them lose their ability to hold water and causing them to be more susceptible to erosion.

Improper disposal of waste is also a significant issue in intensive farming. The high concentration of livestock in factory farms results in a build-up of animal waste. When liquid manure is sprayed onto fields, the amount often exceeds what the crops can absorb, causing the excess to escape into the air or run off into surface waters. This can harm soil health, local water supplies, and human health.

Animal Welfare

Animal agriculture, particularly meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. It is a significant contributor to global warming and climate change, with livestock producing the majority of greenhouse gas emissions from agriculture.

Meat consumption is expected to increase by 40% by 2050, driven by the growing world population and increased per capita consumption, particularly in the developing world. This will have a significant impact on the environment, as the livestock sector already consumes 83% of global arable land.

Solutions

To address the negative impacts of intensive farming, a shift towards more sustainable farming practices and a reduction in meat consumption are necessary. Sustainable farming methods, such as zero-waste agriculture and composting, can help reduce agricultural pollution and improve soil health. Additionally, adopting plant-based diets and reducing meat consumption can significantly mitigate climate change and lower the pressure on natural resources.

The contribution of plastic consumption to climate breakdown and the spread of toxins

Consumption is a major driver of environmental impacts, and plastic consumption is a significant contributor to climate breakdown and the spread of toxins.

Plastic production and disposal emit around 3% of global greenhouse gas emissions, with most emissions coming from the production stage, particularly from converting fossil fuels into plastics. In 2019, the plastic industry added over 850 million metric tons of greenhouse gases to the atmosphere, and by 2050, plastic is predicted to account for up to 13% of the total remaining carbon budget. This will push the planet past the 1.5-degree danger line for global warming.

The entire lifecycle of plastic, from extraction and transport to refining, manufacturing, and waste management, emits greenhouse gases. Single-use packaging is a large and fast-growing area of the plastic economy, and plastic waste is expected to increase to 617 million tons by 2040. Globally, less than 10% of plastic waste is recycled, and plastic that ends up in the environment pollutes the seas, rivers, soils, air, and even living organisms in the form of microplastics and nanoplastics.

Microplastics have been detected in human blood, organs, and semen, and have been linked to harmful health effects. They can pass through the intestinal barrier and enter the bloodstream, reaching the heart, brain, and placenta. Inhaled nanoplastics can disrupt the respiratory system, and exposure to plastic particles has been linked to lung function impairments, inflammation, fibrosis, and even lung cancer. A recent study found a higher risk of myocardial infarction, stroke, and all-cause mortality among individuals with microplastics and nanoplastics in their carotid plaque.

Additionally, chemicals used in plastics, such as phthalates, bisphenol A (BPA), and polybromodiphenyl ethers (PBDEs), have been linked to various health issues. Fetal exposure to PBDEs has been associated with low birth weight and impaired cognitive development in children. BPA exposure has been linked to genital malformations in female newborns, insulin resistance, polycystic ovary syndrome, obesity, hypertension, and cardiovascular disease. DEHP exposure has been linked to miscarriages, genital malformations in male newborns, impaired cognitive development, loss of IQ, early puberty in young girls, and endometriosis.

The economic costs associated with the health impacts of these chemicals have been significant, estimated at $675 billion in the United States alone. Addressing plastic consumption and pollution is crucial for protecting human health and mitigating climate change.
