Environmental issues in the United States include climate change, energy, species conservation, invasive species, deforestation, mining, nuclear accidents, pesticides, pollution, waste and over-population. Despite taking hundreds of measures, the rate of environmental issues is increasing rapidly instead of reducing. The United States is among the most significant emitters of greenhouse gasses in the world. In terms of both total and per capita emissions, it is among the largest contributors.[1] The climate policy of the United States has big influence on the world.[2][3]


Movements and ideas[edit]

20th century[edit]

Both Conservationism and Environmentalism appeared in political debate in forests about the Progressive Era in the early 20th century. There were three main positions. The laissez-faire position held that owners of private property—including lumber and mining companies, should be allowed to do anything they wished for their property.[4]

The Conservationists, led by President Theodore Roosevelt and his close ally Gifford Pinchot, said that the laissez-faire approach was too wasteful and inefficient. In any case, they noted, most of the natural resources in the western states were already owned by the federal government. The best course of action, they argued, was a long-term plan devised by national experts to maximize the long-term economic benefits of natural resources.

Environmentalism was the third position, led by John Muir (1838–1914). Muir's passion for nature made him the most influential American environmentalist. Muir preached that nature was sacred and humans are intruders who should look but not develop. He founded the Sierra Club and remains an icon of the environmentalist movement. He was primarily responsible for defining the environmentalist position, in the debate between Conservation and environmentalism.

Environmentalism preached that nature was almost sacred, and that man was an intruder. It allowed for limited tourism (such as hiking), but opposed automobiles in national parks. It strenuously opposed timber cutting on most public lands, and vehemently denounced the dams that Roosevelt supported for water supplies, electricity and flood control. Especially controversial was the Hetch Hetchy dam in Yosemite National Park, which Roosevelt approved, and which supplies the water supply of San Francisco.

Climate change[edit]

Climate change in the United States refers to historical changes in the climate of the United States, as well as the regional climactic, economic, and cultural responses to global warming.

The current effects of global warming in the United States are widespread and varied. In 2012, the United States experienced its warmest year on record. As of 2012, the thirteen warmest years for the entire planet have all occurred since 1998, transcending those from 1880.[5][6] Different regions experience widely different climatic changes. Changes in climate in the regions of the United States appear significant. For example, drought conditions appear to be worsening in the southwest while improving in the northeast.[7] Generally, states that emit more carbon dioxide per person and block climate action, are suffering more.[8][9] Some research has warned against possible problems due to American climate changes such as the spread of invasive species and possibilities of floods as well as droughts.[10] Climate change is seen as a national security threat to the United States.[11]

The United States is among the most significant emitters of greenhouse gasses in the world. In terms of both total and per capita emissions, it is among the largest contributors.[12]

As of April 2019, 69% of Americans think that climate change is happening and 55% think that it is mostly human caused.[13]

In 2015, according to The New York Times and others, oil companies knew that burning oil and gas could cause global warming since the 1970s but, nonetheless, funded deniers for years.[14][15] 2016 was a historic year for billion-dollar weather and climate disasters in U.S.[16]


Energy[edit]

Since about 26% of all types of energy used in the United States are derived from fossil fuel consumption it is closely linked to greenhouse gas emissions. The energy policy of the United States is determined by federal, state and local public entities, which address issues of energy production, distribution, and consumption, such as building codes and gas mileage advancements. The production and transport of fossil fuels are also tied to significant environmental issues.

Species conservation[edit]

Many plant and animal species became extinct in North America soon after first human arrival, including the North American megafauna; others have become nearly extinct since European settlement, among them the American bison and California condor.[17]

The last of the passenger pigeons died in 1914 after being the most common bird in North America. They were killed as both a source of food and because they were a threat to farming. Saving the bald eagle, the national bird of the U.S., from extinction was a notable conservation success.

As of 13 December, 2016, the International Union for the Conservation of Nature's Red List shows the United States has 1,514 species on its Threatened list (Critically Endangered, Endangered and Vulnerable categories).

Invasive species[edit]

Invasive species are a significant problem, some of the most notable being zebra mussels, Burmese pythons, kudzu, brown tree snakes and European starlings. Economic damages are estimated at $120 billion per year.

Deforestation[edit]

Deforestation in the United States is an ongoing process in the United States. Like deforestation in the rest of the world, it is a complex environmental issue caused by both social and economic pressures.

Prior to the arrival of European-Americans, about one half of the United States land area was forest, about 1,023,000,000 acres (4,140,000 km2) estimated in 1630. Recently, the Forest Service reported total forestation as 766,000,000 acres (3,100,000 km2) in 2012.[18][19][20] The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km2) around 1920.[21] The forest resources of the United States have remained relatively constant through the 20th century.[20] A 2017 study estimated 3 percent loss of forest between 1992-2001.[22]

The 2005 Food and Agriculture Organization (FAO) Global Forest Resources Assessment ranked the United States as seventh highest country losing its old growth forests, a vast majority of which were removed prior to the 20th century.[20]

Mining[edit]

Mining in the United States has been active since the beginning of colonial times, but became a major industry in the 19th century with a number of new mineral discoveries causing a series of mining rushes. In 2015, the value of coal, metals, and industrial minerals mined in the United States was US $109.6 billion. 158,000 workers were directly employed by the mining industry.[23]

The mining industry has a number of impacts on communities, individuals and the environment. Mine safety incidents have been important parts of American occupational safety and health history. Mining has a number of environmental impacts. In the United States, issues like mountaintop removal, and acid mine drainage have widespread impacts on all parts of the environment. As of January 2020. the EPA lists 142 mines in the Superfund program.[24]

Nuclear[edit]

The most notable accident involving nuclear power in the United States was Three Mile Island accident in 1979. Davis-Besse Nuclear Power Station has been the source of two of the top five most dangerous nuclear incidents in the United States since 1979.[25]

Nuclear safety in the United States is governed by federal regulations and continues to be studied by the Nuclear Regulatory Commission (NRC). The safety of nuclear plants and materials controlled by the U.S. government for research and weapons production, as well those powering naval vessels, is not governed by the NRC.

The anti-nuclear movement in the United States consists of more than eighty anti-nuclear groups which have acted to oppose nuclear power and/or nuclear weapons in the USA. The movement has delayed construction or halted commitments to build some new nuclear plants,[26][27] and has pressured the Nuclear Regulatory Commission to enforce and strengthen the safety regulations for nuclear power plants.[28] Anti-nuclear campaigns that captured national public attention in the 1970s and 1980s involved the Calvert Cliffs Nuclear Power Plant, Seabrook Station Nuclear Power Plant, Diablo Canyon Power Plant, Shoreham Nuclear Power Plant, and Three Mile Island.[26]

Pesticides[edit]

Pesticide use in the United States is predominately by the agricultural sector, which in 2012 comprised 89% of conventional pesticide usage in the United States.[29]

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) was first passed in 1947, giving the United States Department of Agriculture responsibility for regulating pesticides. In 1972, FIFRA underwent a major revision and transferred responsibility of pesticide regulation to the Environmental Protection Agency and shifted emphasis to protection of the environment and public health.

Pollution[edit]

As with many countries, pollution in the United States is a concern for environmental organizations, government agencies and individuals.

Pollution from U.S. manufacturing has declined massively since 1990 (despite an increase in production). A 2018 study in the American Economic Review found that environmental regulation is the primary driver of the reduction in pollution.[30]

Air pollution[edit]

Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere, causing harm or discomfort to humans or other living organisms, or damaging ecosystems. Air pollution can cause health problems including (but not limited to) infections, behavioral changes, cancer, organ failure, and premature death. These health effects are not equally distributed across the U.S population; there are demographic disparities by race, ethnicity, socioeconomic status, and education. Air pollution has affected the United States since the beginning of the Industrial Revolution.

According to a 2009 report, around "60 percent of Americans live in areas where air pollution has reached unhealthy levels that can make people sick".[31] Analyzing data from 2016–2018, the American Lung Association found major declines in air quality, including increases in ground-level ozone.[32]

In 2016, a study found that levels of nitrogen oxides had plummeted over the previous decade,[33] due to better regulations, economic shifts, and technological innovations. NASA reported a 32% decrease of nitrogen dioxide in New York City and a 42% decrease in Atlanta between the periods of 2005–2007 and 2009–2011.[citation needed]

Water pollution[edit]

Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although recent regulation has drastically reduced water pollution throughout the nation.[34] Extensive industrialization and rapid urban growth exacerbated water pollution as a lack of regulation allowed for discharges of sewage, toxic chemicals, nutrients and other pollutants into surface water.

In the early 20th century, communities began to install drinking water treatment systems, but control of the principal pollution sources—domestic sewage, industry, and agriculture—was not effectively addressed in the US until the later 20th century. These pollution sources can affect both groundwater and surface water. Multiple pollution incidents such as the Kingston Fossil Plant coal fly ash slurry spill (2008) and the Deepwater Horizon oil spill (2010) have left lasting impacts on water quality, ecosystems, and public health in the United States.[35][36]

Many solutions to water pollution in the United States can be implemented to curtail water pollution. This includes municipal wastewater treatment, agricultural and industrial wastewater treatment, erosion and sediment control, and the control of urban runoff. The continued implementation of pollution prevention, control and treatment measures are used to pursue the goal of maintaining water quality within levels specified in federal and state regulations. However, many water bodies across the country continue to violate water quality standards in the 21st century.[37]

Marine pollution[edit]


Plastic pollution[edit]

United Stated are the biggest creator of plastic waste and the third source of ocean plastic pollution, e.g. plastic waste that gets into the oceans. Many of the plastic waste of the United States is shipped to other countries.[38]

Solid waste[edit]

At 760 kg per person the United States generates the greatest amount of municipal waste.[39] As of 2017, municipal waste totalled 267.8 million tons in total, or 4.51 pounds per person per day.[40]

Policy[edit]

Solid waste policy in the United States is aimed at developing and implementing proper mechanisms to effectively manage solid waste. For solid waste policy to be effective, inputs should come from stakeholders, including citizens, businesses, community based-organizations, non governmental organizations, government agencies, universities, and other research organizations. These inputs form the basis of policy frameworks that influence solid waste management decisions.[41] In the United States, the Environmental Protection Agency (EPA) regulates household, industrial, manufacturing, and commercial solid and hazardous wastes under the 1976 Resource Conservation and Recovery Act (RCRA).[42] Effective solid waste management is a cooperative effort involving federal, state, regional, and local entities.[43] Thus, the RCRA's Solid Waste program section D encourages the environmental departments of each state to develop comprehensive plans to manage nonhazardous industrial and municipal solid waste.[42]
Electronic waste[edit]

Electronic waste or e-waste in the United States refers to electronic products that have reached the end of their operable lives, and the United States is beginning to address its waste problems with regulations at a state and federal level. Used electronics are the quickest-growing source of waste and can have serious health impacts.[44] The United States is the world leader in producing the most e-waste, followed closely by China; both countries domestically recycle and export e-waste.[45] Only recently has the United States begun to make an effort to start regulating where e-waste goes and how it is disposed of. There is also an economic factor that has an effect on where and how e-waste is disposed of. Electronics are the primary users of precious and special metals, retrieving those metals from electronics can be viewed as important as raw metals may become more scarce[46]

The United States does not have an official federal e-waste regulation system, yet certain states have implemented state regulatory systems. The National Strategy for Electronic Stewardship was co-founded by the Environmental Protection Agency (EPA), the Council on Environmental Quality, and the General Services Administration (GSA), and was introduced in 2011 to focus on federal action to establish electronic stewardship in the United States.[47] E-waste management is critical due to the toxic chemicals present in electronic devices. According to the United States EPA, toxic substances such as lead, mercury, arsenic, and cadmium are often released into the environment and endanger whole communities; these toxic contaminants can have detrimental effects on the health of ecosystems and living organisms.[48] United States e-waste management includes recycling and reuse programs, domestic landfill dumping, and international shipments of domestically produced e-waste. The EPA estimates that in 2009, the United States disposed of 2.37 million tons of e-waste, 25% of which was recycled domestically.[48]

Hazardous waste[edit]

Under United States environmental policy, hazardous waste is a waste (usually a solid waste) that has the potential to:

  • cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible illness; or
  • pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed.

Under the 1976 Resource Conservation and Recovery Act (RCRA), a facility that treats, stores or disposes of hazardous waste must obtain a permit for doing so. Generators of and transporters of hazardous waste must meet specific requirements for handling, managing, and tracking waste. Through RCRA, Congress directed EPA to issue regulations for the management of hazardous waste. EPA developed strict requirements for all aspects of hazardous waste management including the treatment, storage, and disposal of hazardous waste. In addition to these federal requirements, states may develop more stringent requirements or requirements that are broader in scope than the federal regulations.

EPA authorizes states to implement the RCRA hazardous waste program. Authorized states must maintain standards that are equivalent to and at least as stringent as the federal program. Implementation of the authorized program usually includes activities such as permitting, corrective action, inspections, monitoring and enforcement.


Population[edit]

The total U.S. population crossed the 100 million mark around 1915, the 200 million mark in 1967, and the 300 million mark in 2006 (estimated on Tuesday, October 17).[49][50] The U.S. population more than tripled during the 20th century — a growth rate of about 1.3 percent a year — from about 76 million in 1900 to 281 million in 2000. This is unlike most European countries, especially Germany, Russia, Italy and Greece, whose populations are slowly declining, and whose fertility rates are below replacement.

Population growth is fastest among minorities, and according to the United States Census Bureau's estimation for 2005, 45% of American children under the age of 5 are minorities.[51] In 2007, the nation’s minority population reached 102.5 million.[52] A year before, the minority population totaled 100.7 million. Hispanic and Latino Americans accounted for almost half (1.4 million) of the national population growth of 2.9 million between July 1, 2005, and July 1, 2006.[53]

Based on a population clock maintained by the U.S. Census Bureau, the current U.S. population, as of 5:55 GMT (EST+5) 27 April 2012 is 316,237,337.[54] A 2004 U.S. Census Bureau report predicted an increase of one third by the year 2050.[55] A subsequent 2008 report projects a population of 439 million, which is a 44% increase from 2008.

Conservation and environmental movement[edit]

Today, the organized environmental movement is represented by a wide range of organizations sometimes called non-governmental organizations or NGOs. These organizations exist on local national and international scales. Environmental NGOs vary widely in political views and in the amount they seek to influence the government. The environmental movement today consists of both large national groups and also many smaller local groups with local concerns. Some resemble the old U.S. conservation movement - whose modern expression is the Nature Conservancy, Audubon Society and National Geographic Society - American organizations with a worldwide influence.
