Global biodiversity is under severe threat, with the IUCN Red List indicating 28% of assessed species face extinction. Habitat destruction, driven by human activities such as deforestation, urbanization, and pollution, is the primary cause. This loss has profound effects on ecosystems, leading to increased human-wildlife conflicts and contributing to climate change and natural disasters. Conservation strategies are vital to mitigate these impacts and preserve our natural world.

The IUCN Red List serves as a critical barometer for the health of the world's biodiversity
Endangered Species
28% of assessed species are at risk of extinction, with mammals and amphibians facing particularly high levels of threat
Leading Cause
Habitat destruction due to human activities is the leading cause of species decline
Human activities such as deforestation, pollution, and urbanization have escalated dramatically in recent centuries, contributing to habitat destruction and species decline
Habitat destruction occurs when a natural environment can no longer support its native species, leading to their decline or extinction
Areas experiencing rapid human population growth and intense resource extraction, such as parts of Africa, South America, and Southeast Asia, are most affected by habitat destruction
Global Issues
Habitat loss contributes to global issues such as climate change and can cause natural disasters like floods and tsunamis
Human-Wildlife Conflicts
Habitat destruction leads to increased encounters between animals and humans, resulting in conflicts and negative impacts for both parties
Habitat destruction is often accompanied by pollution, exacerbating the decline in biodiversity and posing additional health risks to wildlife and human communities alike
The most extensive and persistent damage to habitats is caused by human activities such as resource extraction and infrastructure development
The growth of the human population and the associated demand for resources have led to widespread habitat loss
The development of infrastructure for housing and transportation fragments habitats and increases wildlife mortality due to factors such as roadkill
While natural events like volcanic eruptions and tsunamis can also cause habitat destruction, they are not as significant or persistent as human activities
The 2004 Indian Ocean tsunami reshaped coastal ecosystems and affected species such as saltwater crocodiles in the Andaman and Nicobar Islands
The development of Botum Sakor National Park in Cambodia has led to significant deforestation and the displacement of wildlife and indigenous communities
Urban expansion in Southern California has fragmented mountain lion populations, causing roadkill and genetic isolation
The construction of the U.S.-Mexico border wall poses a threat to the migration patterns and genetic diversity of species like the jaguar, highlighting the negative effects of human infrastructure on wildlife

Purpose of IUCN Red List
Acts as global biodiversity health indicator.
01
Primary cause of species decline
Habitat destruction from human activities.
02
Human activities leading to habitat loss
Deforestation, pollution, urbanization.
