An environmental movement is a social movement concerned with protecting the natural environment, reducing environmental damage and influencing how societies use natural resources, energy, land and ecosystems. Environmental movements can address pollution, climate change, biodiversity loss, deforestation, habitat destruction, waste, water quality, air quality, industrial hazards, resource extraction and environmental justice. The movement is not a single organisation or ideology.
It includes conservation organisations, local community campaigns, climate activism groups, scientific advocacy organisations, Indigenous organisations, youth groups, political organisations and informal networks. Some environmental movements focus on preserving particular places or species, while others address global ecological processes or the relationship between economic systems and environmental degradation. Environmental activism can involve scientific research, public education, lobbying, litigation, consumer campaigns, protests, direct action, conservation projects and participation in formal policy processes.
The modern environmental movement developed from several partly distinct traditions. Conservation movements sought to protect landscapes, wildlife and natural resources, while preservation movements emphasised the protection of areas from human development. Public concern about industrial pollution expanded significantly during the twentieth century as scientific research documented environmental risks. Rachel Carson's 1962 book Silent Spring played an important role in increasing public awareness of pesticide impacts, although environmental concern had important predecessors.
The creation of environmental agencies, environmental legislation and international institutions followed in many countries. Earth Day was first observed in 1970 in the United States and became an internationally recognised environmental event. Later environmental movements increasingly addressed global issues such as climate change, ozone depletion and biodiversity loss. Contemporary environmentalism therefore combines older conservation concerns with newer scientific and political debates about planetary-scale environmental change.
Environmental movements use many different strategies because environmental problems involve governments, corporations, consumers, communities and international institutions. Campaigners may lobby legislators, participate in consultations, bring legal challenges, organise public demonstrations, conduct citizen science, raise funds for conservation or pressure companies through boycotts and shareholder activism. Climate movements may use school strikes, marches, civil disobedience or campaigns for changes in energy policy. Local environmental groups may concentrate on planning decisions, roads, waste facilities, industrial developments or protection of particular habitats.
Digital communication allows campaigns to coordinate across geographical boundaries and circulate scientific information rapidly. Different strategies can produce disagreements within movements about legality, disruption, public communication and the pace of change. Environmental movements are therefore organisationally diverse and cannot be reduced to one preferred form of activism.
A central feature of environmental movements is the connection between human activity and ecological systems. Environmental problems often involve externalities, meaning that some costs of economic activity are imposed on people or ecosystems that are not directly involved in the transaction producing the activity. Pollution is a common example. A factory may generate economic benefits while emissions create health or environmental costs for surrounding communities.
Environmental movements often argue that such costs should be recognised in decision making through regulation, taxation, standards, liability, conservation rules or other mechanisms. Ecological concepts such as ecosystems, biodiversity, carrying capacity, habitat fragmentation, carbon cycles and ecosystem services are therefore important to environmental politics and activism. Environmental movements frequently translate scientific evidence into public and political demands.
Environmental justice has become an important dimension of environmental movements. Environmental burdens and benefits are not always distributed equally between social groups. Communities with fewer political or economic resources may experience disproportionate exposure to pollution, hazardous facilities, poor air quality or environmental degradation. Environmental justice movements connect ecological concerns with questions of race, ethnicity, class, health, land rights and political representation. Indigenous movements have also highlighted relationships between environmental protection, territorial rights, cultural survival and traditional knowledge. This broadens environmentalism beyond the preservation of wilderness by asking who controls natural resources, who experiences environmental risks and who participates in decisions concerning development. Environmental justice therefore links environmental issues to wider questions of inequality and social power.
Climate change has become one of the most prominent issues within contemporary environmental movements. Scientific research has established that human activities, particularly greenhouse gas emissions from fossil fuel combustion, land use change and industrial processes, are causing global warming. Climate movements advocate measures such as reducing emissions, expanding renewable energy, improving energy efficiency, protecting ecosystems and adapting to unavoidable impacts.
Debates within the movement concern the pace of transition, the role of nuclear energy, carbon pricing, technological solutions, lifestyle change, economic growth and the distribution of transition costs. Climate activism also raises questions about intergenerational justice because future generations may experience consequences from emissions produced today. Environmental movements consequently operate at local, national and international scales.
Environmental movements have influenced law, corporate practices, public awareness and international policy. Governments have introduced environmental standards, protected areas, pollution controls and climate policies partly in response to public pressure and scientific evidence. Businesses have developed environmental reporting, sustainability programmes and cleaner technologies, although the effectiveness and sincerity of particular initiatives can vary. Environmental movements also contribute to changing cultural expectations concerning recycling, energy use, conservation and consumption.
Critics sometimes argue that environmental policies can impose unequal costs or restrict economic activity, while environmental activists argue that failing to address ecological damage can create larger long-term social and economic costs. These competing claims demonstrate that environmental politics involves conflicts over evidence, resources, values, regulation and responsibility.
The environmental movement is significant because environmental conditions affect human health, economic activity, food systems, water supplies, biodiversity and the stability of ecological systems on which societies depend. Its concerns range from highly local disputes to global problems requiring international cooperation. Environmental movements combine scientific knowledge, political organisation, community action and cultural change, and their internal diversity means that conservationists, climate campaigners, environmental justice organisations and local activists may pursue different objectives. Understanding the movement requires distinguishing environmental protection from particular political ideologies and recognising that environmental debates involve both empirical questions about ecological effects and normative questions about acceptable risks, responsibilities and priorities.
