When a natural habitat, such as a forest or wetland, is altered so dramatically that it no longer supports the species it originally sustained. habitat destruction. Habitat loss is one of the biggest threats to biodiversity—it is the number one reason species go extinct. Habitat destruction and hunting pressure are widespread in tropical regions (Gallego‐Zamorano et al., 2020; Romero‐Muñoz et al., 2020) and, where these threats co‐occur, they exacerbate biodiversity loss even more than either threat alone (Brook et al., 2008; Mouillot et al., 2013; Peres, 2001). draught.
