Air pollution is the leading environmental risk to health, causing 7 million premature deaths each year. The burden of air pollution is not evenly distributed, with certain groups facing higher exposure to pollutants and greater health risks. Research has consistently shown that racial and ethnic minorities, especially Black, Asian, and Hispanic or Latino populations, are exposed to higher levels of air pollution and face a greater risk of adverse health outcomes as a result. Low-income groups are also disproportionately affected by air pollution, with higher rates of pollution-related diseases and premature deaths. Additionally, outdoor laborers, including migrant and seasonal farmworkers, are among the most vulnerable to air pollution due to their proximity to sources of pollution and limited political power to advocate for improved air quality. Addressing these disparities requires targeted strategies to reduce air pollution and ensure equal protection from environmental hazards for all people, regardless of race, ethnicity, or income level.
What You'll Learn
Fossil fuels
Coal, the dirtiest of all fossil fuels, is responsible for a significant temperature increase globally. Oil, when burned, releases substantial carbon emissions, accounting for approximately one-third of the world's total carbon emissions. Natural gas, often promoted as a cleaner alternative, is still a fossil fuel and contributes to one-fifth of global carbon emissions.
The extraction and production of fossil fuels also contribute to air and water pollution. Drilling, fracking, and mining operations generate vast amounts of wastewater, which can be contaminated with heavy metals, radioactive materials, and other pollutants. These pollutants can leak into waterways and contaminate aquifers, and have severe ecological and health impacts, including cancer, birth defects, and neurological damage. Additionally, the combustion of fossil fuels for energy contributes to smog and soot, which have adverse effects on human health, particularly for vulnerable individuals such as children, the elderly, and those with asthma or allergies.
The impact of fossil fuel pollution is exacerbated by the dominant "take, make, waste" linear economy, where goods are designed to be disposable, further straining the planet's finite resources. Addressing the root causes of pollution and transitioning towards a circular economy that prioritizes regenerative practices are crucial steps in mitigating the harmful effects of fossil fuel pollution.
To summarize, fossil fuels are a significant contributor to pollution, impacting both human health and the environment. The burning of fossil fuels leads to increased carbon emissions, global warming, and climate change. The extraction and production processes also generate air and water pollution, with severe ecological and health consequences. Transitioning to a more sustainable and regenerative economic model is essential to address the detrimental effects of fossil fuel pollution.

Livestock production
The livestock industry is responsible for a significant portion of global greenhouse gas emissions, with estimates ranging from 11.1% to 19.6%. The regular digestive process of ruminants, such as cattle and sheep, produces methane, which is released through burping. Methane is also emitted during the storage of solid waste, such as manure, and during the production and transportation of feed. The expansion of pastureland and cropland for animal grazing and feed crops also leads to the emission of carbon dioxide and the destruction of forests and grasslands.
In addition to greenhouse gas emissions, livestock production contributes to water pollution. The manufacturing of fertilizers and farm inputs, as well as the fertilizing of crops, results in the release of nitrous oxide and carbon dioxide. The improper management of manure can also lead to water contamination. The trend of increasing consumption of animal products exacerbates these issues, particularly in developing countries, where the environmental impact is more severe.
The environmental impact of livestock production is often overlooked, as consumers are disconnected from the processes involved in industrial animal food production. Many people are unaware of the link between their food choices and environmental degradation. However, the livestock industry's contribution to pollution and climate change is significant, and addressing it is crucial for the health and well-being of vulnerable communities and the planet.
To mitigate the environmental impact of livestock production, various interventions can be implemented. These include promoting more sustainable and regenerative agricultural practices, such as the circular economy, improving land-use efficiency, and reducing the consumption of animal products. By addressing the root causes of pollution in the livestock industry, we can work towards healthier and more prosperous communities, while also mitigating the effects of climate change.

Fashion industry
The fashion industry has a significant impact on the environment, with fast fashion being a major contributor to pollution. The industry's environmental impact includes the depletion of non-renewable resources, emissions of greenhouse gases, and the use of vast amounts of water and energy.
Fast fashion is defined by its rapid production cycles, low prices, and high sales volumes. This model promotes overconsumption and excessive production, with consumers buying 60% more garments in 2014 than in 2000 but keeping them for only half as long. The quantity of clothing produced and discarded has skyrocketed, with an estimated 85% of all textiles ending up in landfills each year.
The fashion industry is the second-largest consumer of water, requiring approximately 700 gallons of water to produce one cotton shirt and 2,000 gallons for a pair of jeans. It is estimated that the industry uses 215 trillion litres of water annually, contributing to water degradation and scarcity. The dyeing and finishing processes are particularly harmful, accounting for 36% of the industry's global pollution impact and polluting rivers and streams.
The fashion industry also contributes significantly to air pollution, which is the leading environmental risk to human health, causing approximately seven million premature deaths annually. The production of synthetic fibres, such as polyester, nylon, and acrylic, has increased dramatically since World War II, and these plastic-based textiles have a significant impact on the environment throughout their life cycle. The release of microplastics during the washing of synthetic textiles is a major concern, with an estimated 35% of all microplastics in the ocean originating from laundered synthetic clothing.
Additionally, the fashion industry's carbon emissions are substantial, accounting for about 10% of global carbon emissions, equivalent to the emissions of the entire European Union. The industry's reliance on fossil fuel energy and long supply chains further exacerbates its carbon footprint.
The social and human costs of the fashion industry are also significant, with textile workers in developing countries often subjected to poor working conditions, long hours, and meagre wages. The use of chemicals in clothing production raises health concerns for both workers and consumers, and the industry has been linked to infringements of human rights.
Addressing the environmental and social impacts of the fashion industry requires a shift towards more sustainable practices and business models, such as slow fashion, which emphasizes reduced production, simplified supply chains, and the reuse and maximization of clothing lifespan. Organizations worldwide are advocating for international cooperation and policy changes to promote sustainable fashion and foster a circular economy in the industry.

Food retail
The food retail industry has a significant impact on the environment, contributing to various forms of pollution, including plastic pollution, air pollution, and water pollution.
Plastic pollution is a significant issue in food retail, with plastic packaging being a major concern. Plastic waste, including plastic bags and food packaging, ends up in landfills, oceans, and rivers, leaching hazardous chemicals into the soil and water. Plastic makes up 80% of all marine debris and is lethal to marine life. Additionally, microplastics from plastic packaging can seep into bottled water, posing risks to human health.
Air pollution is another concern, with the food supply chain contributing to emissions of fine particulate matter PM2.5, leading to over 890,000 premature deaths per year, according to a study by the University of Minnesota. The agriculture sector is a significant contributor to these emissions, with livestock farming increasing land-use and contributing to higher PM2.5 emissions. Nitrogen oxides and sulfur dioxide emissions, commonly associated with fossil fuel burning, are also prevalent in food retail, distribution, and transportation.
Water pollution is impacted by food retail, particularly through eutrophication, which is the pollution of waterways with nutrient-rich water. Agriculture is responsible for 78% of global ocean and freshwater eutrophication. Water pollution can accumulate and concentrate in fish, which are then consumed by humans, potentially leading to health risks.
To address these issues, retailers and suppliers can drive demand for sustainable alternatives and incentivize farmers to adopt more biodiversity-positive practices. Reducing the use of environmentally damaging pesticides and fertilizers, as well as limiting intensive farming practices, can help meet global emission reduction targets. Additionally, shifting towards cleaner and more energy-efficient technologies can mitigate the impact of food retail on the environment.
Furthermore, tackling what we eat and how we produce our food is crucial. Red meat products, for example, tend to be associated with higher carbon emissions due to the methane produced by animals. Encouraging consumers, brands, and retailers to work together can support a more sustainable food industry and help address the challenges posed by food retail pollution.
