Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance or energy. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
Smoke is a suspension of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires, but may also be used for pest control (fumigation), communication, defensive and offensive capabilities in the military, cooking, or smoking. It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative.
Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans and their natural, social, and built environments. The philosophy and study of human ecology has a diffuse history with advancements in ecology, geography, sociology, psychology, anthropology, zoology, epidemiology, public health, and home economics, among others.
Chemical waste is any excess, unused, or unwanted chemical, especially those that cause damage to human health or the environment. Chemical waste may be classified as hazardous waste, non-hazardous waste, universal waste, or household hazardous waste. Hazardous waste is material that displays one or more of the following four characteristics: ignitability, corrosivity, reactivity, and toxicity. This information, along with chemical disposal requirements, is typically available on a chemical's Material Safety Data Sheet (MSDS). Radioactive waste requires special ways of handling and disposal due to its radioactive properties. Biohazardous waste, which may contain hazardous materials, is also handled differently.
Green chemistry, similar to sustainable chemistry or circular chemistry, is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. While environmental chemistry focuses on the effects of polluting chemicals on nature, green chemistry focuses on the environmental impact of chemistry, including lowering consumption of nonrenewable resources and technological approaches for preventing pollution.
Environmental racism, ecological racism, or ecological apartheid is a form of institutional racism leading to landfills, incinerators, and hazardous waste disposal being disproportionately placed in communities of color. Internationally, it is also associated with extractivism, which places the environmental burdens of mining, oil extraction, and industrial agriculture upon indigenous peoples and poorer nations largely inhabited by people of color.
Environmental justice or eco-justice, is a social movement to address environmental injustice, which occurs when poor or marginalized communities are harmed by hazardous waste, resource extraction, and other land uses from which they do not benefit. The movement has generated hundreds of studies showing that exposure to environmental harm is inequitably distributed.
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are also available as coatings or sprays to be applied to an object.
Charles Tilly was an American sociologist, political scientist, and historian who wrote on the relationship between politics and society. He was a professor of history, sociology, and social science at the University of Michigan from 1969 to 1984 before becoming the Joseph L. Buttenwieser Professor of Social Science at Columbia University.
A waste picker is a person who salvages reusable or recyclable materials thrown away by others to sell or for personal consumption. There are millions of waste pickers worldwide, predominantly in developing countries, but increasingly in post-industrial countries as well.
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere. There are many different types of air pollutants, such as gases, particulates, and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment or built environment. Air pollution can be caused by both human activities and natural phenomena.
Activism consists of efforts to promote, impede, direct or intervene in social, political, economic or environmental reform with the desire to make changes in society toward a perceived greater good. Forms of activism range from mandate building in a community, petitioning elected officials, running or contributing to a political campaign, preferential patronage of businesses, and demonstrative forms of activism like rallies, street marches, strikes, sit-ins, or hunger strikes.
Environmental issues in Chile include deforestation, water scarcity, pollution, soil erosion, climate change, and biodiversity loss, especially in its industry-heavy "sacrifice zones". The country of Chile is a virtual continental island that spans over 4,200 kilometers. It is bounded by the Pacific Ocean on the west, the Andes Mountains on the east, and the Atacama Desert in the north; it is home to several important eco-regions, such as the Chilean Winter Rainfall-Valdivian Forests, a biodiversity hot-spot that harbors richly endemic flora and fauna, and the Tropical Andes, which stretches into northern Chile. The country has a wide variety of climates due to its large size and extreme geographical features including glaciers, volcanoes, rain forests, and deserts. Chile faces many environmental issues that impact both its people and economy.
The Charles Tilly Award for Best Book is given by the Collective Behavior and Social Movements section of the American Sociological Association in recognition of a significant contribution to the field. Nominees of the award are regarded as being representative of the "best new books in the field of social movements." The award was established in 1986 and is named after sociologist Charles Tilly.
Dorceta E. Taylor is an American environmental sociologist known for her work on both environmental justice and racism in the environmental movement. She is the senior associate dean of diversity, equity, and inclusion at Yale School of the Environment, as well as a professor of environmental justice. Prior to this, she was the director of diversity, equity, and inclusion at the University of Michigan's School of Environment and Sustainability (SEAS), where she also served as the James E. Crowfoot Collegiate Professor of Environmental Justice. Taylor's research has ranged over environmental history, environmental justice, environmental policy, leisure and recreation, gender and development, urban affairs, race relations, collective action and social movements, green jobs, diversity in the environmental field, food insecurity, and urban agriculture.
Toxic abortion is a medical phenomenon of spontaneous abortion, miscarriage, or stillbirth caused by toxins in the environment of the mother during pregnancy, especially as caused by toxic environmental pollutants, though sometimes reported as caused by naturally occurring plant toxins
Cathy Lisa Schneider is an American author and professor of democracy and dictatorship; comparative social movements; political violence; and policing. She is a professor at American University's School of International Service.
Dumping in Dixie is a 1990 book by the American professor, author, activist, and environmental sociologist Robert D. Bullard. Bullard spotlights the quintessence of the economic, social, and psychological consequences induced by the siting of noxious facilities in mobilizing the African American community. Starting with the assertion that every human has the right to a healthy environment, the book documents the journey of five American communities of color as they rally to safeguard their health and homes from the lethal effects of pollution. Further, Bullard investigates the heterogeneous obstacles to social and environmental justice that African American communities often encounter. Dumping in Dixie is widely acknowledged as the first book to discuss environmental injustices and distill the concept of environmental justice holistically. Since the publication of Dumping in Dixie, Bullard has emerged as one of the seminal figures of the environmental justice movement; some even label Bullard as the "father of environmental justice".
The sociology of death explores and examines the relationships between society and death.
Slow violence is violence which occurs gradually and is not necessarily visible. Slow violence is 'incremental and accretive', contrasted with other violences that are spectacular and instantaneous. The key outcome of slow violence is environmental degradation, long-term pollution and climate change. Slow violence is also closely linked to many instances of environmental racism. Rob Nixon states that people lacking resources or people who are living in poverty are the main casualties of slow violence, as it is "built on the bedrock of social inequality".
