Environmental issues are disruptions in the usual function of ecosystems. [1] Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly collapse.

Contents

Environmental protection is the practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism is a social and environmental movement that addresses environmental issues through advocacy, legislation education, and activism. [3]

Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary boundaries. [6] [7] [8] The bulk of environmental impacts are caused by excessive consumption of industrial goods by the world's wealthiest populations. [9] [10] [11] The UN Environmental Program, in its "Making Peace With Nature" Report in 2021, found addressing key planetary crises, like pollution, climate change and biodiversity loss, was achievable if parties work to address the Sustainable Development Goals. [12]

Types

Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming. The UN system has adopted international frameworks for environmental issues in three key issues, which has been encoded as the "triple planetary crises": climate change, pollution, and biodiversity loss. [13]

Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments [14] and to ecosystems, biodiversity, and natural resources [15] caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects [16] [17] including global warming, [14] [18] [19] environmental degradation [14] (such as ocean acidification [14] [20] ), mass extinction and biodiversity loss, [21] [22] [23] ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, [24] [25] [26] neoliberal economic policies [27] [28] [29] and rapid economic growth, [30] overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. [31] [32]

The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. [33] The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. [34] The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment. [35] [36] [37] Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as: electricity, cars, planes, space heating, manufacturing, or the destruction of forests. [38]

Degradation

Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. [39] [40] Environmental degradation process amplify the impact of environmental issues leave lasting impacts on the environment. [41]

Environmental degradation is one of the ten threats officially cautioned by the High-level Panel on Threats, Challenges and Change of the United Nations. The United Nations International Strategy for Disaster Reduction defines environmental degradation as "the reduction of the capacity of the environment to meet social and ecological objectives, and needs". [42]

Environmental degradation comes in many types. When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degredation, such as deforestation which has readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in the climate system. Efforts to counteract this problem include environmental protection and environmental resources management. Mismanagement that leads to degradation can also lead to environmental conflict where communities organize in opposition to the forces that mismanaged the environment.

Environmental conflicts, socio-environmental conflict or ecological distribution conflicts (EDCs) are social conflicts caused by environmental degradation or by unequal distribution of environmental resources. [43] [44] [45] The Environmental Justice Atlas documented 3,100 environmental conflicts worldwide as of April 2020 and emphasised that many more conflicts remained undocumented. [43]

Parties involved in these conflicts include locally affected communities, states, companies and investors, and social or environmental movements; [46] [47] typically environmental defenders are protecting their homelands from resource extraction or hazardous waste disposal. [43] Resource extraction and hazardous waste activities often create resource scarcities (such as by overfishing or deforestation), pollute the environment, and degrade the living space for humans and nature, resulting in conflict. [48] A particular case of environmental conflicts are forestry conflicts, or forest conflicts which "are broadly viewed as struggles of varying intensity between interest groups, over values and issues related to forest policy and the use of forest resources". [49] In the last decades, a growing number of these have been identified globally. [50]

Frequently environmental conflicts focus on environmental justice issues, the rights of indigenous people, the rights of peasants, or threats to communities whose livelihoods are dependent on the ocean. [43] Outcomes of local conflicts are increasingly influenced by trans-national environmental justice networks that comprise the global environmental justice movement. [43] [51]

Environmental conflict can complicate response to natural disaster or exacerbate existing conflicts –especially in the context of geopolitical disputes or where communities have been displaced to create environmental migrants. [52] [45] [48] The study of these conflicts is related to the fields of ecological economics, political ecology, and environmental justice.

Justice

This section is an excerpt from Environmental justice.[ edit ]

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. [53] The movement has generated hundreds of studies showing that exposure to environmental harm is inequitably distributed. [54]

The movement began in the United States in the 1980s. It was heavily influenced by the American civil rights movement and focused on environmental racism within rich countries. The movement was later expanded to consider gender, international environmental injustice, and inequalities within marginalised groups. As the movement achieved some success in rich countries, environmental burdens were shifted to the Global South (as for example through extractivism or the global waste trade). The movement for environmental justice has thus become more global, with some of its aims now being articulated by the United Nations. The movement overlaps with movements for Indigenous land rights and for the human right to a healthy environment. [55]

The goal of the environmental justice movement is to achieve agency for marginalised communities in making environmental decisions that affect their lives. The global environmental justice movement arises from local environmental conflicts in which environmental defenders frequently confront multi-national corporations in resource extraction or other industries. Local outcomes of these conflicts are increasingly influenced by trans-national environmental justice networks. [56] [57]

Environmental justice scholars have produced a large interdisciplinary body of social science literature that includes contributions to political ecology, environmental law, and theories on justice and sustainability. [53] [58] [59]

The 2023 IPCC report highlighted the disproportionate effects of climate change on vulnerable populations. The report's findings make it clear that every increment of global warming exacerbates challenges such as extreme heatwaves, heavy rainfall, and other weather extremes, which in turn amplify risks for human health and ecosystems. With nearly half of the world's population residing in regions highly susceptible to climate change, the urgency for global actions that are both rapid and sustained is underscored. The importance of integrating diverse knowledge systems, including scientific, Indigenous, and local knowledge, into climate action is highlighted as a means to foster inclusive solutions that address the complexities of climate impacts across different communities. [60]

In addition, the report points out the critical gap in adaptation finance, noting that developing countries require significantly more resources to effectively adapt to climate challenges than what is currently available. This financial disparity raises questions about the global commitment to equitable climate action and underscores the need for a substantial increase in support and resources. The IPCC's analysis suggests that with adequate financial investment and international cooperation, it is possible to embark on a pathway towards resilience and sustainability that benefits all sections of society. [60]

Law

This section is an excerpt from Environmental law.[ edit ]
Environmental laws are laws that protect the environment. [61] Environmental law is the collection of laws, regulations, agreements and common law that governs how humans interact with their environment. [62] This includes environmental regulations; laws governing management of natural resources, such as forests, minerals, or fisheries; and related topics such as environmental impact assessments. Environmental law is seen as the body of laws concerned with the protection of living things (human beings inclusive) from the harm that human activity may immediately or eventually cause to them or their species, either directly or to the media and the habits on which they depend. [63]

Assessment

This section is an excerpt from Environmental impact assessment.[ edit ]

Environmental Impact assessment (EIA) is the assessment of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term "strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. [64] [65] It is a tool of environmental management forming a part of project approval and decision-making. [66] Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review.

The purpose of the assessment is to ensure that decision-makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an environmental impact assessment as "the process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made". [67] EIAs are unique in that they do not require adherence to a predetermined environmental outcome, but rather they require decision-makers to account for environmental values in their decisions and to justify those decisions in light of detailed environmental studies and public comments on the potential environmental impacts. [68]

Movement

The environmental movement (sometimes referred to as the ecology movement), is a social movement that aims to protect the natural world from harmful environmental practices in order to create sustainable living. [69] Environmentalists advocate the just and sustainable management of resources and stewardship of the environment through changes in public policy and individual behavior. [70] In its recognition of humanity as a participant in (not an enemy of) ecosystems, the movement is centered on ecology, health, as well as human rights.

The environmental movement is an international movement, represented by a range of environmental organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest, the movement includes private citizens, professionals, religious devotees, politicians, scientists, nonprofit organizations, and individual advocates like former Wisconsin Senator Gaylord Nelson and Rachel Carson in the 20th century.

Organizations

Environmental issues are addressed at a regional, national or international level by government organizations.

The largest international agency, set up in 1972, is the United Nations Environment Programme. The International Union for Conservation of Nature brings together 83 states, 108 government agencies, 766 Non-governmental organizations and 81 international organizations and about 10,000 experts, scientists from countries around the world. [71] International non-governmental organizations include Greenpeace, Friends of the Earth and World Wide Fund for Nature. Governments enact environmental policy and enforce environmental law and this is done to differing degrees around the world.

Film and television

There are an increasing number of films being produced on environmental issues, especially on climate change and global warming. Al Gore's 2006 film An Inconvenient Truth gained commercial success and a high media profile.

<span class="mw-page-title-main">Biodiversity</span> Variety and variability of life forms

Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem levels. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of Earth's terrestrial surface and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Marine coastal biodiversity is highest globally speaking in the Western Pacific ocean steered mainly by the higher surface temperatures. In all oceans across the planet, marine species diversity peaks in the mid-latitudinal zones. Terrestrial species threatened with mass extinction can be observed in exceptionally dense regional biodiversity hotspots, with high levels of species endemism under threat. There are 36 such hotspot regions which require the world's attention in order to secure global biodiversity.

The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment's maximal load, which in population ecology corresponds to the population equilibrium, when the number of deaths in a population equals the number of births. The effect of carrying capacity on population dynamics is modelled with a logistic function. Carrying capacity is applied to the maximum population an environment can support in ecology, agriculture and fisheries. The term carrying capacity has been applied to a few different processes in the past before finally being applied to population limits in the 1950s. The notion of carrying capacity for humans is covered by the notion of sustainable population.

Overconsumption describes a situation where a consumer overuses their available goods and services to where they can't, or don't want to, replenish or reuse them. In microeconomics, this may be described as the point where the marginal cost of a consumer is greater than their marginal utility. The term overconsumption is quite controversial in use and does not necessarily have a single unifying definition. When used to refer to natural resources to the point where the environment is negatively affected, it is synonymous with the term overexploitation. However, when used in the broader economic sense, overconsumption can refer to all types of goods and services, including manmade ones, e.g. "the overconsumption of alcohol can lead to alcohol poisoning". Overconsumption is driven by several factors of the current global economy, including forces like consumerism, planned obsolescence, economic materialism, and other unsustainable business models and can be contrasted with sustainable consumption.

<span class="mw-page-title-main">Conservation biology</span> Study of threats to biological diversity

Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management.

<span class="mw-page-title-main">Habitat conservation</span> Management practice for protecting types of environments

Habitat conservation is a management practice that seeks to conserve, protect and restore habitats and prevent species extinction, fragmentation or reduction in range. It is a priority of many groups that cannot be easily characterized in terms of any one ideology.

<span class="mw-page-title-main">Environmental protection</span> Practice of protecting the natural environment

Environmental protection is the practice of protecting the natural environment by individuals, groups and governments. Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends.

An ecological or environmental crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include:

<span class="mw-page-title-main">Environmental degradation</span> Any change or disturbance to the environment perceived to be deleterious or undesirable

Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. Environmental degradation process amplify the impact of environmental issues leave lasting impacts on the environment.

<span class="mw-page-title-main">Habitat destruction</span> Process by which a natural habitat becomes incapable of supporting its native species

Habitat destruction occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.

<span class="mw-page-title-main">Human impact on the environment</span> Impact of human life on Earth and environment

Human impact on the environment refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation, mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species.

<span class="mw-page-title-main">Ecosystem service</span> Benefits provided by healthy nature, forests and environmental systems

Ecosystem services are the many and varied benefits to humans provided by the natural environment and healthy ecosystems. Such ecosystems include, for example, agroecosystems, forest ecosystem, grassland ecosystems, and aquatic ecosystems. These ecosystems, functioning in healthy relationships, offer such things as natural pollination of crops, clean air, extreme weather mitigation, and human mental and physical well-being. Collectively, these benefits are becoming known as ecosystem services, and are often integral to the provision of food, the provisioning of clean drinking water, the decomposition of wastes, and the resilience and productivity of food ecosystems.

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.

<span class="mw-page-title-main">Ecological resilience</span> Capacity of ecosystems to resist and recover from change

In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and subsequently recovering. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil, and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. When such thresholds are associated with a critical or bifurcation point, these regime shifts may also be referred to as critical transitions.

<span class="mw-page-title-main">Deforestation in Nigeria</span>

Deforestation in Nigeria refers to the extensive and rapid clearing of forests within the borders of Nigeria. This environmental issue has significant impacts on both local and global scales.

<span class="mw-page-title-main">Sustainability</span> Goal of people safely co-existing on Earth

Sustainability is a social goal for people to co-exist on Earth over a long time. Definitions of this term are disputed and have varied with literature, context, and time. Experts often describe sustainability as having three dimensions : environmental, economic, and social, and many publications emphasize the environmental dimension. In everyday use, sustainability often focuses on countering major environmental problems, including climate change, loss of biodiversity, loss of ecosystem services, land degradation, and air and water pollution. The idea of sustainability can guide decisions at the global, national, and individual levels. A related concept is sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal, while sustainable development refers to the many processes and pathways to achieve it."

<span class="mw-page-title-main">Planetary boundaries</span> Limits not to be exceeded if humanity wants to survive in a safe ecosystem

Planetary boundaries are a framework to describe limits to the impacts of human activities on the Earth system. Beyond these limits, the environment may not be able to self-regulate anymore. This would mean the Earth system would leave the period of stability of the Holocene, in which human society developed. The framework is based on scientific evidence that human actions, especially those of industrialized societies since the Industrial Revolution, have become the main driver of global environmental change. According to the framework, "transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing thresholds that will trigger non-linear, abrupt environmental change within continental-scale to planetary-scale systems."

<span class="mw-page-title-main">Biodiversity loss</span> Extinction of species or loss of species in a given habitat

Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent. It is temporary if the damage that led to the loss is reversible in time, for example through ecological restoration. If this is not possible, then the decrease is permanent. The cause of most of the biodiversity loss is, generally speaking, human activities that push the planetary boundaries too far. These activities include habitat destruction and land use intensification. Further problem areas are air and water pollution, over-exploitation, invasive species and climate change.

Environmentalism of the poor is a set of social movements that arise from environmental conflicts when impoverished people struggle against powerful state or private interests that threaten their livelihood, health, sovereignty, and culture. Part of the global environmental justice movement, it differs from mainstream environmentalism by emphasizing social justice issues instead of emphasizing conservation and eco-efficiency. It is becoming an increasingly important force for global sustainability.

Still increasing by roughly 80 million people per year, or more than 200,000 per day (figure 1a–b), the world population must be stabilized—and, ideally, gradually reduced—within a framework that ensures social integrity. There are proven and effective policies that strengthen human rights while lowering fertility rates and lessening the impacts of population growth on GHG emissions and biodiversity loss. These policies make family-planning services available to all people, remove barriers to their access and achieve full gender equity, including primary and secondary education as a global norm for all, especially girls and young women (Bongaarts and O'Neill 2018).

Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance. As the amount of carbon dioxide in the atmosphere rises, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid. This causes the acidity of seawater to increase.
