Summary
Biodiversity loss refers to the decline or disappearance of biological diversity, encompassing the variety of genes, species, and ecosystems. This loss is a significant environmental and societal concern, driven primarily by human activities like habitat destruction, climate change, and overexploitation of natural resources. The consequences include ecosystem degradation, reduced resilience to environmental changes, and threats to human well-being, including food security.
Biodiversity loss has far-reaching consequences, requiring urgent action to protect the planet’s rich web of life.

News
Earth.org, – May 30, 2025
Collaboration among researchers, policymakers, and civil society is needed to reverse biodiversity loss in Europe and create a nature-positive future for the continent. The European Union-funded project BIOTraCes employs an innovative approach to the problem, focussing on tackling the root causes of biodiversity loss, emphasizing equity and justice for both people and the planet.
Biodiversity in Europe is facing a significant and ongoing decline. Data from the European Environment Agency indicates that nearly 40% of the 463 bird species in the European Union (EU) are classified as having poor or bad conservation status. Approximately 5% of habitats require improvement, and 50% of dunes, bogs, mires, and fens are in a state of poor conservation.
The main pressure on biodiversity in our continent comes from the agriculture sector, which accounts for 21% of the impact on habitats and species, followed by urbanization at 13% and forestry at 11%.
“Growing economies coincide with increased exploitation and extraction of resources, which leads to climate change, land use, and alteration,” said Esther Turnhout, a partner in the EU-funded project Biodiversity and Transformative Change for plural and nature positive societies (BIOTraCes) at the University of Twente in the Netherlands. “This, in turn, results in biodiversity loss.”

Causes of Biodiversity Loss
- Habitat Loss and DegradationConversion of natural areas for agriculture, urbanization, and infrastructure development reduces the space available for species to live and thrive.
- Climate ChangeRising temperatures, altered precipitation patterns, and extreme weather events disrupt ecosystems and force species to migrate or face extinction.
- OverexploitationUnsustainable harvesting of natural resources, such as overfishing and illegal wildlife trade, depletes populations and disrupts ecological balance.
- PollutionChemicals, plastics, and other pollutants contaminate air, water, and soil, harming species and their habitats.
- Invasive SpeciesNon-native species can outcompete native species for resources or prey on them, disrupting ecosystems and causing declines in native populations.
Problems
Biodiversity, the variety of life on Earth, is currently facing a serious crisis, with species disappearing at an unprecedented rate. The World Economic Forum identified biodiversity loss as the third greatest risk to the world in 2020.
These interconnected challenges are accelerating the loss of biodiversity, impacting ecosystem stability, essential ecosystem services, and human well-being, says Earth.Org. Urgent and collaborative action is needed to reverse this decline and safeguard the planet’s diverse web of life.

1. Habitat loss and degradation
- The expansion of agriculture, urbanization, logging, and infrastructure development leads to the destruction and fragmentation of natural habitats like forests, wetlands, and grasslands.
- Forests alone are home to over 80% of terrestrial animal, plant, and insect species, making deforestation a critical concern.
2. Climate change
- Rising global temperatures, altered weather patterns, and extreme weather events disrupt ecosystems and threaten species’ ability to adapt or migrate.
- Examples include melting ice disrupting polar bear food sources and warming oceans causing coral bleaching.
3. Pollution
- Various forms of pollution, including air, water, and soil contamination, introduce harmful substances into ecosystems.
- Industrial emissions, chemical runoff, pesticides, and plastic waste disrupt natural processes and harm or kill plants and animals.
4. Overexploitation of species
- Unsustainable harvesting of resources, such as overfishing and overhunting, depletes populations and disrupts ecosystems.
- The illegal wildlife trade further exacerbates this problem, pushing many species towards extinction, according to Earth.Org.
5. Invasive species
- Non-native species introduced into new environments can outcompete native species for resources, prey upon them, or introduce diseases.
- Invasive species are considered the second biggest cause of biodiversity loss globally, according to the United Nations Development Programme (UNDP).
Research
The global biodiversity crisis necessitates innovative and collaborative solutions to combat the decline of species and ecosystems. Current research and innovations are focusing on several key areas, leveraging technology, scientific understanding, and community engagement to drive more effective conservation efforts.
The integration of these diverse research areas and innovative solutions, coupled with continued investment and collaboration, is essential to addressing the complex challenge of biodiversity loss and fostering a more biodiverse and resilient planet.
