What are the 5 main causes of habitat loss?
The main causes of habitat degradation is pollution, invasive species, agricultural development, diminished resources, such as water and food, urban sprawl, logging, mining, destructive fishing practices and the disruption of ecosystem processes, such as altering the intensity and frequency of fires in an ecosystem.
When animals are removed from their natural habitat?
When an animal loses the natural home or habitat that it needs to survive, its numbers decline rapidly, and it moves toward extinction. It’s estimated that 14,000 to 35,000 species are at risk of becoming extinct, and habitat destruction is one of the main causes.
