Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic eruptions. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.
The National Oceanic and Atmospheric Administration is an American scientific agency within the United States Department of Commerce that focuses on the conditions of the oceans, major waterways, and the atmosphere.
The Environmental Protection Agency (EPA) is an independent agency of the United States federal government for environmental protection. President Richard Nixon proposed the establishment of EPA on July 9, 1970 and it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the President and approved by Congress. The current Administrator is former Deputy Administrator Andrew R. Wheeler, who had been acting administrator since July 2018. The EPA is not a Cabinet department, but the Administrator is normally given cabinet rank.
Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems.
Superfund is a United States federal government program designed to fund the cleanup of sites contaminated with hazardous substances and pollutants. Sites managed under this program are referred to as "Superfund" sites. It was established as the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). It authorizes federal natural resource agencies, primarily the Environmental Protection Agency (EPA), states and Native American tribes to recover natural resource damages caused by hazardous substances, though most states have and most often use their own versions of CERCLA. CERCLA created the Agency for Toxic Substances and Disease Registry (ATSDR). The EPA may identify parties responsible for hazardous substances releases to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund and costs recovered from polluters by referring to the U.S. Department of Justice.
The Ontario Agricultural College (OAC) originated at the agricultural laboratories of the Toronto Normal School, and was officially founded in 1874 as an associate agricultural college of the University of Toronto. Since 1964, it has become affiliated with the University of Guelph, which operates four campuses throughout Ontario.
Environmental design is the process of addressing surrounding environmental parameters when devising plans, programs, policies, buildings, or products. Classical prudent design may have always considered environmental factors; however, the environmental movement beginning in the 1940s has made the concept more explicit.
Environmentally friendly or environment-friendly, are sustainability and marketing terms referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment. Companies use these ambiguous terms to promote goods and services, sometimes with additional, more specific certifications, such as ecolabels. Their overuse can be referred to as greenwashing.
Environmental psychology is an interdisciplinary field that focuses on the interplay between individuals and their surroundings. It examines the way in which the natural environment and our built environments shape us as individuals. The field defines the term environment broadly, encompassing natural environments, social settings, built environments, learning environments, and informational environments.
Environmental justice emerged as a concept in the United States in the early 1980s. The term has two distinct uses with the more common usage describing a social movement that focuses on the fair distribution of environmental benefits and burdens. The other use is an interdisciplinary body of social science literature that includes theories of the environment and justice, environmental laws and their implementations, environmental policy and planning and governance for development and sustainability, and political ecology.
Environmental education (EE) refers to organized efforts to teach how natural environments function, and particularly, how human beings can manage behavior and ecosystems to live sustainably. It is a multi-disciplinary field integrating disciplines such as biology, chemistry, physics, ecology, earth science, atmospheric science, mathematics, and geography. The United Nations Educational, Scientific and Cultural Organisation (UNESCO) states that EE is vital in imparting an inherent respect for nature amongst society and in enhancing public environmental awareness. UNESCO emphasises the role of EE in safeguarding future global developments of societal quality of life (QOL), through the protection of the environment, eradication of poverty, minimization of inequalities and insurance of sustainable development. The term often implies education within the school system, from primary to post-secondary. However, it sometimes includes all efforts to educate the public and other audiences, including print materials, websites, media campaigns, etc.. There are also ways that environmental education is taught outside the traditional classroom. Aquariums, zoos, parks, and nature centers all have ways of teaching the public about the environment.
Environmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues. These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the protection of natural resources, wildlife and endangered species. Concerning environmental policy, the importance of implementation of an eco-energy-oriented policy at a global level to address the issues of global warming and climate changes should be accentuated. Policies concerning energy or regulation of toxic substances including pesticides and many types of industrial waste are part of the topic of environmental policy. This policy can be deliberately taken to direct and oversee human activities and thereby prevent harmful effects on the biophysical environment and natural resources, as well as to make sure that changes in the environment do not have harmful effects on humans.
GRID-Arendal is a centre collaborating with the United Nations Environment Programme, located in Arendal, Norway. The centre was established in 1989 by the Norwegian Government as a non-profit foundation to support the United Nations in the field of environmental information management and assessment, capacity-building and communications and outreach. It is part of the GRID network of environmental data and information centers, under the UN Environment Division of early warning and assessment. The GRID program itself was established in 1985 as a part of Earthwatch with the goal of providing useful environmental data to researchers and policy makers. GRID centers also support developing countries through training programs and transfer of technology pertinent to geographic information systems and remote sensing.
