Detailed explanation-1: -Habitat loss and fragmentation are currently the main threats to terrestrial biodiversity. Anthropogenic disturbance such as agricultural expansion has resulted in dramatic global habitat loss and fragmentation.

Detailed explanation-2: -The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally.

Detailed explanation-3: -Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

Detailed explanation-4: -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-5: -Effects of habitat loss on biodiversity Habitat loss has been generally associated to drastic declines in overall abundance and diversity of marine organisms. For example, in the Wadden Sea, the destruction of biogenic habitats has caused the regional extinction of at least 26 species during the past 2000 years.
