Giraffes feed on leaves, stems, flowers and fruits, so human population growth and habitat loss can hurt the species. Instances of drought have also led to increased human-wildlife conflicts.
Habitat destruction. Map of the world's biodiversity hot spots, all of which are heavily threatened by habitat loss and degradation. Habitat destruction (also termed habitat loss and habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or ...
Biodiversity loss happens when plant or animal species disappear completely from Earth (extinction) or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. [2] Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [3] (suspected of being one of the ...
However, most habitat loss is hard to see.” Fireflies are associated with a wide range of habitats depending on the species, according to experts with the Xerces Society Firefly Atlas .
A pathogen that has never once been exposed to a specific species' evolutionary pathway can have detrimental impacts on the population. In most cases, these risks escalate in conjunction to other anthropogenic stressors, such as climate change or habitat loss, that ultimately lead a population to extinction without human intervention.

Habitat loss, disease and climate change are thought to be responsible for the drastic decline in populations in recent years. [ 12 ] Declines have been particularly intense in the western United States , Central America , South America , eastern Australia and Fiji (although cases of amphibian extinctions have appeared worldwide).
The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world. The Zoological Society of London (ZSL) manages the index in cooperation with the World Wide Fund for Nature (WWF). As of 2022, the index is statistically created from journal ...
