Global attention is finally starting to focus on global climate change impacts. However, this may pale in comparison to the causes of the extinction crisis currently happening (UN Report: Nature’s Dangerous Decline ‘Unprecedented’; Species Extinction Rates ‘Accelerating’). The planet currently faces an extinction crisis well above the historic background rate attributed to far more pressing concerns: deforestation, land conversion, hunting, over-fishing, pollution, and invasive species introductions.
Biodiversity loss, often referred to as the "extinction crisis," is a critical global issue that encompasses the rapid decline of species diversity and the deterioration of ecosystems worldwide. This phenomenon is primarily driven by human activities, including habitat destruction, climate change, pollution, over-exploitation of natural resources, and other anthropogenic impacts. As the planet faces an unprecedented acceleration in species extinction rates, the consequences reverberate across ecosystems, affecting ecological balance, resilience, and the overall health of our planet.
Conservation efforts are essential to mitigate the ongoing biodiversity loss and address the ecological challenges associated with it. Scientists and environmentalists emphasize the urgency of preserving endangered species, protecting their habitats, and implementing sustainable practices to ensure the long-term health of ecosystems. The term "extinction crisis" underscores the severity of the situation, emphasizing that we are witnessing a historical moment where the delicate web of life on Earth is unraveling at an alarming pace.
In the face of the extinction crisis, conservation biology has emerged as a multidisciplinary field dedicated to understanding and addressing the complex interactions between human activities and the natural world. Researchers, policymakers, and conservationists collaborate to develop strategies and interventions aimed at halting or reversing the decline of biodiversity. These strategies involve creating protected areas, implementing sustainable land-use practices, combating illegal wildlife trade, and raising awareness about the importance of biodiversity for human well-being.
The extinction crisis is not merely an environmental issue; it has profound implications for human societies. Biodiversity loss can disrupt ecosystems that provide essential services such as pollination of crops, water purification, and disease regulation. The decline of keystone species can trigger cascading effects throughout entire ecosystems, leading to unforeseen and potentially irreversible consequences.
Addressing the extinction crisis requires a global commitment to conservation, sustainable development, and responsible stewardship of the planet's resources. As we navigate the challenges posed by climate change and human impact, there is an increasing recognition that the fate of humanity is intricately linked to the health of the natural world. The extinction crisis compels us to reevaluate our relationship with the environment and take decisive actions to protect the rich tapestry of life on Earth for current and future generations.
And yet, the global discourse largely focuses on global climate change while ignoring the equally important impacts of species extinction, trophic cascades, and collapse of ecosystem services. Yes, climate change is one driver of species extinctions, but it by no means is the only one (Ceballos et al. 2015).
A recent report by the International Union for Conservation of Nature (IUCN) suggests that of 105,000 species being monitored, 27% are at risk of going extinct. And worse, not a single one has improved over the past year.

Other findings:
- Three-quarters of the land-based environment and about 66% of the marine environment have been significantly altered by human actions.
- On average these trends have been less severe or avoided in areas held or managed by Indigenous Peoples and Local Communities.
- More than a third of the world’s land surface and nearly 75% of freshwater resources are now devoted to crop or livestock production.
- 60 billion tons of renewable and nonrenewable resources are now extracted globally every year – having nearly doubled since 1980.
- Annual global crops are at risk from pollinator loss and 100-300 million people are at increased risk of floods and hurricanes because of loss of coastal habitats and protection.
- 33% of marine fish stocks are being harvested at unsustainable levels; 60% are maximally sustainably fished, with just 7% harvested at levels lower than what can be sustainably fished.
- Plastic pollution has increased tenfold since 1980, 300-400 million tons of heavy metals, solvents, toxic sludge and other wastes from industrial facilities are dumped annually into the world’s waters, and fertilizers entering coastal ecosystems have produced more than 400 ocean ‘dead zones’, totalling more than 245,000 km2 (591-595).
- Negative trends in nature will continue to 2050 and beyond in all of the policy scenarios explored in the Report, except those that include transformative change – due to the projected impacts of increasing land-use change, exploitation of organisms and climate change, although with significant differences between regions.
