Alarming Rise in Extinction Risk: Two Million Species at Stake, Double Previous UN Estimates


A new analysis has revealed a staggering figure of two million species at risk of extinction, doubling previous estimates by the United Nations. While the decline of plant and vertebrate species has been well-documented, uncertainty regarding insects has always prevailed. However, recent data has shown that insects are under much more significant threat than previously estimated. This revelation is crucial considering that insects make up the most species-rich group of animals on Earth. Published in Plos One, this study calls for immediate action to address the alarming plight of insect populations.

The Silent Crisis: Insects Under Threat:

Lead researcher Axel Hochkirch from the Musee National d’Histoire Naturelle in Luxembourg asserts that this study effectively highlights the vulnerability of insects, putting them at par with other endangered animals. Given that insects constitute over 90% of the invertebrate group, their imperilment effectively doubles the global number of vulnerable species. This discovery warrants urgent attention to ensure their survival and preserve the delicate balance of our planet’s ecosystems.

The Challenge of Understanding Global Insect Decline:

Understanding the state of global insect populations has been a challenging task due to limited data. However, it is essential to recognize that invertebrates account for a staggering 97% of all animal species. Insects, in particular, contribute significantly to ecosystem services such as crop pollination, nutrient recycling, and waste decomposition. According to Hochkirch, the planet’s survival is intrinsically linked to the survival of insects. Therefore, gaining insight into their decline becomes vital in assessing the overall health of our ecosystems.

The European Perspective: A Warning Signal:

To shed light on the situation, the research team delved into the International Union for Conservation of Nature’s red list of threatened species, which serves as the most comprehensive information source on endangered species. Focusing on European species, the analysis unveiled that a fifth of all European species faces a risk of extinction. The study further reveals that 24% of invertebrates, 27% of plants, and 18% of vertebrates in Europe are critically endangered. These figures act as a stark warning sign, indicative of the larger global crisis looming over the planet.

The Indispensable Role of Insects in Ecosystems:

Insects play a vital role in maintaining ecosystem balance. They facilitate the pollination of crops, ensuring adequate food production, and enabling biodiversity. Additionally, insects play a significant part in recycling nutrients, thereby contributing to soil health and productivity. They also aid in the decomposition of waste, promoting the elimination of harmful substances from the environment. The loss of these invaluable contributions would irreversibly impact the functioning of ecosystems and jeopardize our planet’s overall sustainability.

Addressing the Crisis: Urgent Action is Imperative:

In light of the alarming findings, immediate and effective action must be taken to combat the crisis facing insect populations. Preserving natural habitats, reducing pesticide use, and implementing sustainable agricultural practices are crucial steps. Collaboration between governments, scientists, environmental organizations, and the general public is necessary to raise awareness, advocate for policy changes, and promote conservation efforts. Funding for research and monitoring programs focused on insects is also vital, as it will enable a more comprehensive understanding of the challenges they face and lead to targeted solutions.

Concluding Thoughts:

The revelation that two million species are at risk of extinction, double the previous UN estimates, sends a strong message about the urgency of addressing the global crisis faced by insects. These findings highlight the inherent interconnectedness of all life forms on Earth and emphasize the pivotal role insects play in maintaining our planet’s delicate ecosystems. By acknowledging and taking action to protect insect populations, humanity can safeguard its own future while securing the diverse beauty and resilience of the natural world.
