The organized environmental movement is represented by a wide range of non-governmental organizations or NGOs that seek to address environmental issues in the United States. They operate on local, national, and international scales. Environmental NGOs vary widely in political views and in the ways they seek to influence the environmental policy of the United States and other governments.
Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature.
Environmental science is an interdisciplinary academic field that integrates physics, biology, meteorology, mathematics and geography 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.
A geographer is a physical scientist, social scientist or humanist whose area of study is geography, the study of Earth's natural environment and human society, including how society and nature interacts. The Greek prefix "geo" means "earth" and the Greek suffix, "graphy", meaning "description", so a geographer is someone who studies the earth. The word "geography" is a Middle French word that is believed to have been first used in 1540.
Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of the U.N.'s Convention on Biodiversity.
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.
A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or human-made features, often considered in terms of their aesthetic appeal. A landscape includes the physical elements of geophysically defined landforms such as mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity.
Susan Augusta Fenimore Cooper was an American writer and amateur naturalist. She founded an orphanage in Cooperstown, New York and made it a successful charity. The daughter of writer James Fenimore Cooper, she served as his secretary and amanuensis late in his life.
The concept of race as a categorization of anatomically modern humans has an extensive history in Europe and the Americas. The contemporary word race itself is modern; historically it was used in the sense of "nation, ethnic group" during the 16th to 19th centuries. Race acquired its modern meaning in the field of physical anthropology through scientific racism starting in the 19th century. With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsolete. In 2019, the American Association of Biological Anthropologists stated: "The belief in 'races' as natural aspects of human biology, and the structures of inequality (racism) that emerge from such beliefs, are among the most damaging elements in the human experience both today and in the past."
The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:
George Perkins Marsh, an American diplomat and philologist, is considered by some to be America's first environmentalist and by recognizing the irreversible impact of man's actions on the earth, a precursor to the sustainability concept, although "conservationist" would be more accurate. The Marsh-Billings-Rockefeller National Historical Park in Vermont takes its name, in part, from Marsh. His 1864 book Man and Nature had a great impact in many parts of the world.

Callicott held the position of Professor of Philosophy and Natural Resources at the University of Wisconsin–Stevens Point from 1969 to 1995, where he taught the world's first course in environmental ethics in 1971. From 1994 to 2000, he served as vice president then president of the International Society for Environmental Ethics. Other distinguished positions include visiting professor of philosophy at Yale University; the University of California, Santa Barbara; the University of Hawaiʻi; and the University of Florida.
Environmental history is the study of human interaction with the natural world over time, emphasising the active role nature plays in influencing human affairs and vice versa.
Antonio Stoppani was an Italian Catholic priest, patriot, geologist and palaeontologist. He studied the geology of the Italian region and wrote a popular treatise, Il Bel Paese, on geology and natural history. He was among the first to propose a geological epoch dominated by human activities that altered the shape of the land.
Ellen Churchill Semple was an American geographer and the first female president of the Association of American Geographers. She contributed significantly to the early development of the discipline of geography in the United States, particularly studies of human geography. She is most closely associated with work in anthropogeography and environmentalism, and the debate about "environmental determinism".
Pantropy is a hypothetical process of space habitation or space colonization in which, rather than terraforming other planets or building space habitats suitable for human habitation, humans are modified to be able to thrive in the existing environment. The term was coined by science fiction author James Blish, who wrote a series of short stories based on the idea.
The World Without Us is a 2007 non-fiction book about what would happen to the natural and built environment if humans suddenly disappeared, written by American journalist Alan Weisman and published by St. Martin's Thomas Dunne Books. It is a book-length expansion of Weisman's own February 2005 Discover article "Earth Without People". Written largely as a thought experiment, it outlines, for example, how cities and houses would deteriorate, how long man-made artifacts would last, and how remaining lifeforms would evolve. Weisman concludes that residential neighborhoods would become forests within 500 years, and that radioactive waste, bronze statues, plastics and Mount Rushmore would be among the longest-lasting evidence of human presence on Earth.
This timeline of the history of environmentalism is a listing of events that have shaped humanity's perspective on the environment. This timeline includes human induced disasters, environmentalists that have had a positive influence, and environmental legislation.
