Explanation: 

Detailed explanation-1: -Forest fragmentation is the breaking of large, contiguous forested areas into smaller forest patches, separated by roads, agriculture, utility corridors or other anthropological developments. It is a gradual process which starts with smaller, discontinuous patches in an otherwise unbroken forest or grassland.

Detailed explanation-2: -Destruction and degradation of natural ecosystems are the primary causes of declines in global biodiversity (1, 2). Habitat destruction typically leads to fragmentation, the division of habitat into smaller and more isolated fragments separated by a matrix of human-transformed land cover.

Detailed explanation-3: -Major Kinds of Habitat Loss Other ways people directly destroy habitat include filling in wetlands, dredging rivers, mowing fields, and cutting down trees.
