Ethics and Values: This topic explores the ethical and moral values that underlie our relationship with the environment and the need to integrate them into policies, decision-making, and behavior.
Environmental Health: This topic explores the relationship between environmental factors and human health, and the strategies for preventing, diagnosing, and treating environmentally induced diseases.
Biodiversity and Habitat Conservation: This topic covers the importance of biodiversity, the threats to biodiversity, and the measures taken to conserve habitats and species.
Ocean Pollution: This topic elaborates on the sources, types, and effects of ocean pollution, and the measures to reduce it.
Environmental Art: This topic explores the role of art in raising awareness about environmental issues, promoting sustainable practices, and inspiring social change.
Environmental Philosophy: This topic explores different schools of environmental philosophy and their views on the relationship between humans and the environment, and the ethical dimensions of environmental issues.
Ecotourism and Wildlife Conservation: This topic covers the concept of ecotourism and its role in promoting environmental awareness, responsible travel, and the conservation of wildlife and natural habitats.
Air pollution: The presence of harmful substances such as gases, particulate matter, and chemicals in the air.
Water pollution: Contamination of water bodies such as rivers, lakes, oceans, and groundwater due to the release of harmful substances.
Soil pollution: Contamination of the soil with harmful chemicals, radioactive materials, or other pollutants, which can make the land unfit for agricultural purposes.
Noise pollution: The presence of excessive noise in the environment from sources such as transportation, machinery, and construction.
Thermal pollution: The increase in temperature of natural water bodies due to the discharge of hot water from power plants or factory processes, which can harm aquatic life.
Light pollution: The excessive and intrusive presence of artificial light in the environment, which can affect ecosystems, wildlife, and human health.
Radioactive pollution: The release of radioactive materials into the environment, which can cause long-term damage to human health and the environment.
Visual pollution: The presence of unsightly structures, advertisements, and debris in the environment, which can detract from the natural beauty of an area.
Biological pollution: The introduction of non-native species into an ecosystem or the release of harmful pathogens, which can cause harm to native species and disrupt ecosystem functioning.
Plastic pollution: The accumulation of plastic waste in the environment, particularly in oceans and other bodies of water, which can cause harm to marine life and the ecosystem.
"Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution."
"Pollutants can be either foreign substances/energies or naturally occurring contaminants."
"Sources created by human activities, such as manufacturing, extractive industries, poor waste management, transportation, or agriculture."
"Pollution is often classed as point source or nonpoint source pollution."
"Many sources of pollution were unregulated parts of industrialization during the 19th and 20th centuries until the emergence of environmental regulation and pollution policy in the later half of the 20th century."
"In 2019, pollution killed nine million people worldwide (one in six deaths), a number unchanged since 2015."
"Air pollution accounted for 3⁄4 of these earlier deaths."
"A 2022 literature review found that levels of anthropogenic chemical pollution have exceeded planetary boundaries and now threaten entire ecosystems around the world."
"Pollutants frequently have outsized impacts on vulnerable populations, such as children and the elderly, and marginalized communities."
"Polluting industries and toxic waste sites tend to be collocated with populations with less economic and political power."
"This outsized impact is a core reason for the formation of the environmental justice movement."
"The outsized impact on marginalized communities continues to be a core element of environmental conflicts."
"Local, country, and international policy have increasingly sought to regulate pollutants, resulting in increasing air and water quality standards, alongside regulation of specific waste streams."
"Regional and national policy is typically supervised by environmental agencies or ministries."
"International efforts are coordinated by the UN Environmental Program and other treaty bodies."
"Pollution mitigation is an important part of all of the Sustainable Development Goals."
"In 2019, pollution killed nine million people worldwide (one in six deaths)."
"Air pollution accounted for 3⁄4 of these earlier deaths."
"A number unchanged since 2015."
