Habitat loss is the primary threat.
A large portion of the world's biodiversity is at risk.

Threats to Biodiversity (Details)

Habitat Loss: The most significant cause of extinction; human activities and land use change.
Alien/Exotic species: Introductions disrupt ecosystem balance, compete with or prey on native species.
Pollution: Includes acid deposition, eutrophication, ozone depletion, organic chemicals, and climate change.
Overexploitation: Overuse of natural resources, illegal practices like poaching.
Disease: An emerging threat due to the spread of pathogens.

Habitat Loss (Details)

Habitat loss affects all ecosystems, but tropical rainforests and coral reefs are particularly vulnerable due to their high biodiversity.
Land conversion, urbanization, and agricultural activities cause habitat loss in various areas, including tropical forests and coastal regions.
Loss of coastal habitats may significantly impact the ecosystems there.

Alien/Exotic Species (Details)

Worldwide, colonization led to the introduction of species.
For example, the introduction of foxes in New Zealand impacted local bird species.
Horticulture and agriculture may result in escaping species.
Examples like Kudzu in the U.S. demonstrate the detrimental effects of invasive species.
Accidental transport, such as the introduction of zebra mussels, significantly impacts the invaded areas.

Pollution (Details)
