⛑️Public Health Ethics Unit 9 – Environmental Health: Ethics & Policy

Key Concepts in Environmental Health

• Environmental health focuses on the interrelationships between human health and the natural and built environments
• Encompasses the assessment and control of environmental factors that can potentially affect health (air pollution, water quality, chemical exposure)
• Considers both the direct pathological effects of chemicals, radiation, and biological agents, as well as the effects on health of the broad physical and social environment
  • Includes housing, urban development, land-use and transportation, industry, and agriculture
• Emphasizes preventive measures to reduce environmental health risks and protect populations
• Recognizes the disproportionate impact of environmental hazards on vulnerable populations (low-income communities, children, elderly)
• Involves multidisciplinary approaches from fields such as toxicology, epidemiology, environmental sciences, and public policy
• Requires consideration of the complex interactions between environmental factors and human health outcomes
  • For example, air pollution can exacerbate respiratory conditions like asthma and contribute to cardiovascular disease

Ethical Frameworks in Environmental Policy

• Utilitarianism evaluates actions based on their consequences and aims to maximize overall welfare or well-being
  • Supports policies that provide the greatest good for the greatest number of people
• Deontology emphasizes moral duties and obligations, such as the duty to prevent harm and respect individual rights
  • Argues for the inherent value of the environment and the moral obligation to protect it
• Virtue ethics focuses on character traits and moral virtues, such as compassion, integrity, and environmental stewardship
• Environmental justice considers the fair distribution of environmental benefits and burdens across different populations
  • Addresses the disproportionate impact of environmental hazards on marginalized communities
• Precautionary principle states that when an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause-and-effect relationships are not fully established scientifically
• Sustainability ethics emphasizes the importance of meeting the needs of the present without compromising the ability of future generations to meet their own needs
• Ecocentric ethics extends moral consideration to all living beings and ecosystems, recognizing their intrinsic value beyond human use

Major Environmental Health Challenges

• Air pollution from sources like industrial emissions, transportation, and household fuel combustion contributes to respiratory and cardiovascular diseases
• Water pollution and lack of access to safe drinking water and sanitation facilities lead to waterborne illnesses (cholera, typhoid)
• Climate change impacts, such as extreme weather events, rising sea levels, and changes in disease vector distribution, pose risks to human health
  • Heat waves can cause heat stress, dehydration, and exacerbate cardiovascular conditions
• Exposure to toxic chemicals, such as pesticides, heavy metals, and persistent organic pollutants, can have acute and chronic health effects (cancer, neurodevelopmental disorders)
• Food safety concerns, including foodborne illnesses and contamination of food supplies with chemicals or pathogens
• Environmental degradation, such as deforestation, soil erosion, and biodiversity loss, can affect food security, water resources, and ecosystem services
• Occupational health hazards, particularly in industries with high exposure to chemicals, dust, or physical hazards (mining, agriculture, manufacturing)
• Urban health challenges related to overcrowding, inadequate housing, and lack of green spaces in rapidly growing cities

Policy Development and Implementation

• Involves identifying environmental health problems, setting priorities, and formulating policies to address them
• Requires consideration of scientific evidence, risk assessment, and cost-benefit analysis in decision-making processes
• Engages stakeholders, including government agencies, industry, non-governmental organizations, and affected communities, in policy development
• Utilizes various policy instruments, such as regulations, standards, economic incentives, and voluntary agreements, to achieve environmental health goals
  • For example, setting air quality standards, implementing carbon pricing mechanisms, or providing subsidies for clean energy technologies
• Ensures effective implementation and enforcement of policies through monitoring, inspections, and penalties for non-compliance
• Incorporates principles of environmental justice and equity in policy design and implementation
  • Addresses the disproportionate impact of environmental hazards on vulnerable populations
• Requires coordination and collaboration across different sectors and levels of government (local, regional, national)
• Adapts to changing scientific knowledge, technological advancements, and societal values over time

Stakeholder Analysis and Engagement

• Identifies and maps the various individuals, groups, and organizations that have an interest or stake in an environmental health issue
  • Includes affected communities, government agencies, industry, non-governmental organizations, and academic institutions
• Assesses the interests, influence, and power dynamics among different stakeholders
• Engages stakeholders through participatory processes, such as public consultations, workshops, and advisory committees, to gather input and build consensus
• Ensures meaningful participation of marginalized and vulnerable populations in decision-making processes
  • Provides accessible information, language translation, and culturally appropriate engagement methods
• Facilitates dialogue and negotiation among stakeholders with conflicting interests or values
• Incorporates stakeholder perspectives and knowledge in problem definition, policy formulation, and implementation
• Builds trust and transparency through regular communication and information sharing with stakeholders
• Evaluates and adapts stakeholder engagement strategies throughout the policy development and implementation process

Case Studies in Environmental Ethics

• Love Canal, New York: A neighborhood built on a former chemical waste dump, leading to health problems and relocation of residents, raises questions of corporate responsibility and government oversight
• Flint Water Crisis, Michigan: Contamination of the city's water supply with lead due to cost-cutting measures and inadequate treatment, disproportionately affecting low-income and minority communities
• Deepwater Horizon Oil Spill, Gulf of Mexico: The largest marine oil spill in history, causing extensive ecological damage and economic losses, highlighting the risks of offshore drilling and the need for stronger safety regulations
• Bhopal Gas Tragedy, India: A gas leak at a pesticide plant exposed over 500,000 people to toxic chemicals, resulting in thousands of deaths and long-term health effects, raising issues of corporate negligence and inadequate emergency response
• Chevron-Texaco Oil Pollution, Ecuador: Decades of oil extraction in the Amazon rainforest led to widespread environmental contamination and health problems for indigenous communities, leading to a long-running legal battle over corporate accountability
• Minamata Disease, Japan: Industrial discharge of methylmercury into Minamata Bay contaminated fish and shellfish, causing severe neurological disorders in the local population and leading to stricter regulations on industrial waste
• Three Gorges Dam, China: The construction of the world's largest hydroelectric dam displaced over a million people and caused significant ecological impacts, illustrating the trade-offs between development and environmental conservation

Global Perspectives and International Agreements

• Stockholm Declaration (1972) was the first major international conference on environmental issues, recognizing the importance of environmental protection and sustainable development
• Montreal Protocol (1987) is an international treaty designed to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances
• Basel Convention (1989) controls the transboundary movement and disposal of hazardous wastes, aiming to protect human health and the environment
• United Nations Framework Convention on Climate Change (UNFCCC) (1992) provides a framework for international cooperation to combat climate change and adapt to its effects
  • Kyoto Protocol (1997) and Paris Agreement (2015) are subsequent agreements under the UNFCCC, setting targets for greenhouse gas emissions reduction
• Convention on Biological Diversity (1993) aims to conserve biodiversity, promote sustainable use of its components, and ensure fair and equitable sharing of benefits from genetic resources
• Rotterdam Convention (1998) promotes shared responsibility and cooperative efforts in the international trade of certain hazardous chemicals, through information exchange and informed consent procedures
