What is the Single Greatest Threat to Biodiversity

Question

What is the single greatest threat to biodiversity?
A) overharvesting of commercially important species
B) introduced species that compete with native species
C) pollution of Earth's air, water, and soil
D) disruption of trophic relationships as more and more prey species become extinct
E) habitat alteration, fragmentation, and destruction

Accepted Answer

Habitat alteration, fragmentation, and destruction are the greatest threats to biodiversity, as they directly result in the loss of habitats and ecosystems that support a vast array of species. These changes are often caused by human activities, such as deforestation, urbanization, and agriculture. They can lead to the displacement of species, the loss of genetic diversity, and ultimately, the extinction of entire populations.
