Habitat fragmentation is a landscape-level phenomenon in which a once-continuous habitat is broken into smaller, spatially isolated patches separated by a matrix of modified or unsuitable land cover. It encompasses reductions in patch size, increased edge-to-interior ratios, and isolation effects that alter species movement, gene flow, metapopulation dynamics, and community composition. Fragmentation modifies abiotic conditions (e.g., microclimate, hydrology), disrupts ecological interactions such as pollination and predation, and can increase extinction risk, invasion susceptibility, and biotic homogenization. It is typically quantified using metrics of patch configuration, connectivity, and edge density in landscape ecology and conservation biology.
A study of changes to the habitats of more than 700 species reveals massive biodiversity loss—but also possibilities for restoration. "There is a lot of talk about deforestation and biodiversity loss in the Amazon, but even ...

Imagine an asteroid striking Earth and wiping out most of the human population. Even if some lucky people survived the impact, Homo sapiens might still face extinction, because the social networks humans rely on would collapse.
