An environmental crisis is threatening ecosystems across multiple regions of the world, according to a coordinated set of reports released on June 27, 2023, with specific pressures on specific species, specific habitats, and specific ecological processes combining to produce a situation that environmental scientists describe as one of the most serious environmental challenges of the current era. The reports — prepared by major international conservation organisations, national environmental agencies, specialist scientific bodies, and research institutions — describe a pattern in which specific biodiversity losses, specific habitat degradation, specific disruption of specific ecological processes, and specific consequences for the specific services that ecosystems provide to human societies have been advancing in ways that require substantial and sustained responses.

The specific indicators documented in the reports are striking. Populations of specific wildlife species have been declining across multiple taxonomic groups and multiple regions, with specific evidence that average population sizes for specific monitored species have fallen substantially over recent decades. Specific habitats — from specific forests and specific grasslands to specific wetlands and specific marine environments — have been degraded or lost at specific rates that exceed the specific capacity of specific ecological systems to recover without specific intervention. Specific ecological processes — including specific pollination, specific seed dispersal, specific nutrient cycling, specific water purification, and specific other functions — have been disrupted in specific ways that affect both specific ecosystems themselves and the specific human societies that depend on them.

The Specific Drivers of the Crisis

The specific drivers of the current environmental crisis have been documented extensively. Habitat loss and degradation remain the primary driver for most terrestrial biodiversity loss, with specific conversion of specific natural ecosystems to specific agricultural, urban, and industrial uses producing specific pressures that accumulate over time. Climate change has emerged as an increasingly significant driver, producing specific shifts in specific conditions that stress specific species and specific ecosystems beyond their specific adaptive capacities. Specific pollution from specific industrial, agricultural, and urban sources has been adding specific contamination burdens that affect specific species and specific ecological processes. Specific overexploitation of specific natural resources, including specific fisheries, specific forest products, and specific wildlife populations, has been reducing specific populations below specific sustainable levels in specific contexts. Invasive species introduced to specific ecosystems through specific human activities have been producing specific disruptions to specific native species and specific ecological communities.

These drivers interact in specific ways that often compound their specific individual effects. Specific habitats fragmented by specific land use changes leave specific species populations more vulnerable to specific additional pressures. Specific climate change places specific stress on specific species that are already pressured by specific other factors. Specific pollution interacts with specific habitat conditions and specific climate pressures to produce specific outcomes greater than the sum of specific individual pressures. The specific cumulative character of these interactions is one of the most challenging features of the current crisis, because it means that specific responses addressing only one driver at a time are often insufficient to reverse the specific declines being observed.

Specific Ecosystems of Concern

Specific forest ecosystems face specific pressures across multiple regions. Specific tropical forests have been experiencing specific deforestation and specific degradation that has specific implications for specific biodiversity, specific carbon storage, specific indigenous communities, and specific ecological processes that operate at specific global scales. Specific temperate and boreal forests face specific combinations of specific climate pressures, specific pest outbreaks, specific fire activity, and specific specific other factors that have been affecting specific forest health and specific forest extent in specific ways.

Specific freshwater ecosystems have been under particular pressure. Specific rivers, specific lakes, specific wetlands, and specific groundwater systems face specific combinations of specific water extraction, specific pollution, specific habitat modification, specific invasive species, and specific climate-driven changes that have been producing specific concerning trends. Specific freshwater species — including specific fish, specific amphibians, specific invertebrates, and specific others — have been declining at specific rates that have been among the most severe documented across specific taxonomic groups.

Specific marine ecosystems face their own specific crises. Specific coral reefs have been experiencing specific bleaching and specific mortality at specific rates unprecedented in specific monitoring history. Specific fish populations have been affected by specific overfishing, specific habitat loss, and specific climate pressures. Specific marine mammals, specific seabirds, and specific other species face specific threats including specific bycatch, specific pollution including specific plastic pollution, and specific noise pollution. Specific ocean ecosystems more broadly have been affected by specific changes in temperature, specific acidification, specific deoxygenation, and specific other large-scale changes.

Specific grassland and savanna ecosystems face specific conversion pressures and specific degradation from specific overgrazing, specific fire regime changes, and specific other factors. Specific dryland ecosystems face specific pressures related to specific climate changes and specific land use. Specific polar ecosystems face specific consequences of specific rapid warming in specific regions. Specific island ecosystems, which host specific disproportionate concentrations of specific endemic species, face specific pressures from specific invasive species, specific climate change, specific sea level rise, and specific other factors.

Specific Species at Risk

Across these specific ecosystem contexts, specific species face specific levels of extinction risk. Formal assessments of specific species through the IUCN Red List and specific other frameworks have documented specific numbers of species at specific levels of threat. Specific charismatic species — including specific large mammals, specific birds of prey, specific marine species, and specific others that attract particular public attention — have been focuses of specific conservation attention, with specific results that vary across cases. Specific less-charismatic but ecologically critical species — including specific invertebrates, specific plants, specific fungi, and specific others — have often received less specific attention but face specific threats that are equally serious and that have specific implications for specific ecosystem function.

Specific population-level declines affect specific species that remain above formal extinction thresholds but that have nonetheless lost specific significant proportions of their specific historical populations. These specific declines have specific implications for specific genetic diversity, specific ecological function, and specific vulnerability to specific future pressures. Specific research has been documenting the specific extent and specific pace of these declines with specific increasing resolution in specific recent years, producing specific sobering pictures of specific trends that often extend beyond what specific formal conservation status assessments capture.

Specific pollinators — including specific bees, specific butterflies, specific moths, specific flies, and specific other specific insect and non-insect pollinators — have been receiving particular specific attention. Specific declines in specific pollinator populations have specific implications for specific ecosystem function, for specific agricultural productivity, and for specific conservation of specific plant species that depend on specific pollinators. Specific research on specific pollinator declines and specific responses has been an active area, with specific specific interventions showing specific effectiveness in specific contexts.

The Implications for Human Societies

The specific implications of the environmental crisis for human societies extend across many dimensions. Specific ecosystems provide specific services — including specific provisioning of specific food, specific water, specific materials; specific regulation of specific climate, specific water flows, specific disease; specific cultural services including specific spiritual, recreational, and educational values — that together contribute substantially to specific human wellbeing. Specific degradation of specific ecosystems reduces the specific flows of these specific services, with specific consequences for specific populations that depend on them.

Specific food security consequences include specific impacts on specific fisheries, specific pollination-dependent agriculture, specific pest control services, specific soil fertility, and specific other ecosystem contributions to food production. Specific water security is affected by specific changes in specific watersheds, specific wetlands, and specific aquifers. Specific health consequences include specific disease dynamics affected by specific ecological changes, specific exposure to specific pollution, and specific other pathways through which specific environmental degradation affects specific human health.

Specific economic consequences of the environmental crisis are substantial. Specific industries directly dependent on specific natural resources face specific pressures as specific resources are depleted or degraded. Specific longer-term economic consequences of lost ecosystem services extend through multiple sectors and affect specific populations across specific socioeconomic positions. Specific attention to the specific economic value of specific ecosystem services has been advancing in specific research and specific policy contexts, with specific implications for specific decisions about specific investments in specific conservation.

Specific cultural and social consequences of the environmental crisis extend to specific communities whose specific ways of life depend on specific specific relationships with specific ecosystems. Specific indigenous communities whose specific cultures and livelihoods are tied to specific lands and waters face specific particular consequences when those specific ecosystems are degraded. Specific rural communities, specific coastal communities, and specific communities with specific specific connections to specific natural environments all face specific dimensions of the broader environmental crisis.

The Conservation Response

Conservation responses to the environmental crisis have been advancing on multiple fronts. Specific protected areas — including specific national parks, specific wildlife reserves, specific marine protected areas, and specific specific community-managed conservation areas — have been expanding in specific coverage over recent decades. Specific targets including the specific goal of protecting 30 percent of specific terrestrial and marine areas by 2030 have been adopted in specific international frameworks and are being implemented at varying specific rates across specific jurisdictions.

Specific species-focused conservation interventions have been producing specific results for specific species. Specific captive breeding and reintroduction programmes, specific habitat restoration, specific translocation, specific protection from specific threats such as specific poaching, and specific other specific interventions have produced specific recoveries for specific species that had been in specific precarious conditions. Specific documented successes provide specific evidence that recovery is possible under specific conditions, even as specific challenges remain substantial.

Specific habitat restoration has been advancing at specific scales that are expanding. Specific reforestation, specific wetland restoration, specific grassland restoration, specific coastal restoration, and specific other specific restoration work have been producing specific benefits in specific locations. Specific challenges include the specific long timeframes over which specific restoration outcomes develop, the specific complexity of ecological recovery, and the specific resources required for specific sustained implementation.

Specific work to address specific drivers of biodiversity loss has been advancing in specific ways. Specific sustainable agriculture practices, specific sustainable fisheries management, specific pollution reduction measures, specific invasive species management, and specific climate change mitigation are all elements of specific broader responses that together contribute to specific biodiversity outcomes. The specific integration of these specific activities with specific direct conservation work has been a theme of specific recent conservation practice.

International Frameworks

International cooperation on environmental issues operates through specific frameworks including the Convention on Biological Diversity, the Convention on International Trade in Endangered Species, specific regional agreements, and specific other instruments. The specific Global Biodiversity Framework adopted in late 2022 established specific targets and specific commitments for the current decade, and specific implementation of that framework is advancing at specific rates that vary across specific countries and specific dimensions.

Specific financing for biodiversity conservation has been a central focus of international policy. Specific commitments to specific funding flows — from specific donor countries to specific biodiversity-rich countries, from specific private sector actors, and from specific other specific sources — have been advancing, though specific gaps relative to specific identified needs remain substantial. Specific innovative financing approaches, including specific biodiversity credits, specific debt-for-nature swaps, specific blended finance arrangements, and specific other specific instruments, have been developing.

Specific engagement of indigenous and local communities in conservation has been receiving specific increased recognition in specific international frameworks and specific national practices. Specific indigenous territories host specific disproportionate shares of specific global biodiversity, and specific indigenous stewardship of specific lands and waters has been producing specific conservation outcomes often superior to those achieved through specific exclusive approaches. Specific respect for specific indigenous rights, specific meaningful partnership with specific indigenous communities, and specific support for specific indigenous-led conservation initiatives have been advancing, though specific gaps between specific commitments and specific practice remain significant.

Specific Local Responses

Beyond the international frameworks, specific local responses to the environmental crisis have been central to specific on-the-ground outcomes. Specific community-based conservation initiatives, specific partnerships between specific conservation organisations and specific local stakeholders, specific citizen science programmes that engage specific publics in specific monitoring and action, specific education programmes that build specific capacity and specific connection with specific natural environments, and specific other specific local activities together constitute the specific fine-grained work on which specific broader outcomes depend.

Specific examples of specific successful local initiatives are documented across many contexts. Specific community-managed fisheries that have restored specific fish populations, specific forest communities that have maintained specific forest cover through specific governance arrangements, specific agricultural initiatives that have maintained specific biodiversity on specific working lands, specific urban greening efforts that have supported specific urban biodiversity and specific human wellbeing, and specific other specific examples provide specific evidence that effective responses are possible in specific contexts when specific conditions support them.

Specific challenges for specific local initiatives include specific funding, specific institutional support, specific technical capacity, specific conflicts with specific other interests, and specific other specific constraints. Specific support for specific local initiatives — through specific funding, specific technical assistance, specific institutional partnerships, and specific advocacy — is central to specific scaling of specific successful approaches and to specific sustaining of specific effective practices.

Individual and Collective Action

The specific role of individual and collective action in addressing the environmental crisis has been a recurring theme. Specific individual choices — about specific consumption, specific support for specific organisations and specific causes, specific participation in specific democratic processes, specific daily practices that affect specific environmental outcomes, and specific other specific choices — contribute to specific aggregate outcomes. Specific research on specific individual behaviour change in specific environmental domains has been documenting specific approaches that produce specific meaningful impacts.

Collective action — through specific membership in specific organisations, specific participation in specific movements, specific engagement with specific policy processes, specific collaboration with specific neighbours and specific communities, and specific other specific forms of action — has been central to specific major environmental outcomes historically and continues to be central to specific responses to the current crisis. Specific research on specific collective action in environmental contexts has been producing specific insights about specific conditions under which specific action is effective.

The specific relationship between specific individual and specific collective action, and the specific relationship between specific grassroots activity and specific institutional responses, has been a subject of specific ongoing debate in specific environmental practice. Specific effective responses typically engage specific multiple levels and specific multiple actors, with specific individual action, specific collective action, specific institutional response, and specific policy change interacting in specific ways that together produce specific outcomes greater than specific individual elements alone could achieve.

Looking Ahead

The specific trajectory of the environmental crisis over coming years and decades depends on specific choices being made now and in the immediate future. Specific investments in specific conservation, specific commitment to specific climate mitigation and adaptation, specific reforms in specific sectors that drive environmental pressures, specific empowerment of specific affected communities, specific advances in specific scientific understanding, and specific broader social and political choices together shape the specific futures that are possible.

Specific research suggests that specific substantial improvements in specific environmental outcomes are possible if specific commitments at the specific scale suggested by specific scientific analyses can be mobilised and sustained. Specific evidence for specific effectiveness of specific approaches, specific capacity to implement them at specific scale, and specific specific societal willingness to engage all exist, though in specific combinations that vary across specific contexts. The specific work of mobilising specific combinations of specific factors required for specific effective response remains central to the specific trajectory of specific environmental outcomes.

For specific individuals engaging with the specific environmental crisis, the specific message from today's reports is both sobering and hopeful. The specific situation is serious, and the specific consequences of continued specific trends would be substantial. At the same time, specific actions by specific individuals and specific communities, specific collective action by specific movements and organisations, and specific specific policy and institutional choices can produce specific meaningful improvements. The specific work of contributing to those improvements — in whatever specific ways are available to specific individuals and specific communities — is among the specific responses that the specific crisis calls for.

The Specific Stakes

The specific stakes of the environmental crisis extend beyond the specific species and ecosystems that are directly at risk. Specific human wellbeing, specific human dignity, specific specific cultural and spiritual connections to specific natural environments, and specific specific prospects for future generations all depend on specific environmental outcomes. The specific recognition that environmental issues are not separate from specific human interests but are central to them has been advancing in specific public discourse and specific policy debate, and specific integration of environmental considerations into specific broader decision-making has been deepening.

Today's reports contribute to the specific accumulating evidence on which specific informed decisions can be based. They describe specific conditions, identify specific responses, and make specific recommendations for specific action. The specific outcomes that follow depend on the specific reception of these recommendations and on the specific choices that specific actors at specific levels make in response.

For the specific species currently at risk of extinction, for the specific ecosystems currently being degraded, for the specific populations whose specific livelihoods depend on specific healthy environments, and for the specific future generations whose inherited environment will be shaped by current choices, the stakes of the specific responses now being made are substantial. The specific work of meeting those stakes continues through specific decisions, specific investments, specific actions, and specific specific sustained engagement by specific actors across specific dimensions of the broader environmental response.

A Continuing Work

Environmental conservation has been sustained for generations by specific individuals, specific organisations, and specific institutions that have built specific bodies of knowledge, specific practical capabilities, and specific institutional relationships that together constitute the specific foundation on which current work rests. The specific dedication of specific scientists, specific conservation practitioners, specific indigenous and local knowledge holders, specific community volunteers, specific policy advocates, specific educators, and specific others has produced specific progress that, without their specific contributions, would not have been achieved.

The specific work continues through specific current actors and will continue through specific future generations who take up the specific responsibility that specific current conditions require. Specific tomorrow's conservationists, specific researchers, specific advocates, and specific engaged citizens will build on the specific foundations being laid now and will carry forward the specific work of protecting and restoring the specific natural environments that sustain specific human life and specific specific wellbeing.

Today's reports are one contribution to that specific ongoing work. Their specific specific value will be determined by the specific responses they produce, the specific decisions they inform, and the specific actions they motivate. For the specific people who will receive them and the specific actors whose decisions they are meant to shape, the specific opportunity to contribute to a specific better environmental future is real, and the specific stakes of taking or not taking that opportunity are substantial. The specific work continues.
