LIFE SCIENCE

Detailed explanation-1: -Orangutans, tigers, elephants, rhinos, and many other species are increasingly isolated and their sources of food and shelter are in decline. Human-wildlife conflict also increases because without sufficient natural habitat these species come into contact with humans and are often killed or captured.

Detailed explanation-2: -Habitat and biodiversity loss. One of the major ways that habitat fragmentation affects biodiversity is by reducing the amount of suitable habitat available for organisms. Habitat fragmentation often involves both habitat destruction and the subdivision of previously continuous habitat.

Detailed explanation-3: -Habitat Fragmentation Increases Overall Richness, but Not of Habitat-Dependent Species. Debate rages as to whether habitat fragmentation leads to the decline of biodiversity once habitat loss is accounted for.
