Habitat Loss

Abstract

Habitat loss refers to the disappearance of natural environments that house specific plant and animal species. Habitat loss encompass three main types: habitat destruction, degradation, and fragmentation. Habitat destruction involves extensive devastation of natural environments, habitat degradation results from the depletion of vital resources like water and food, and habitat fragmentation refers to the conversion of large wild areas into smaller ones. All forms of habitat loss are endangering species’ survival. Primarily driven by human activities, the loss of habitat adversely affects terrestrial and aquatic ecosystems. Land conversion for agriculture, mining, and urban development leads to the loss of forests and other habitats. Aquatic environments also suffer habitat loss caused by dredging, pollution, or waste. Moreover, climate change, a consequence of global warming, further intensifies habitat loss. Droughts, floods, wildfires, and changing water conditions impact both terrestrial and aquatic habitats. Although the link between habitat destruction and criminology may not be immediately apparent, its harmful effects make it of interest to criminologists. Green criminology’s focus on harms, along with crimes and the impacts of these harms toward all species and environments, makes habitat loss of key interest for criminology. Habitat loss falls under the scope of green criminology because of its effects on ecosystems, humans, and nonhuman species. It is important to note that habitat and biodiversity loss are deeply intertwined. The case of the European eel illustrates the (slow) violence linked to habitat loss and its effects on biodiversity. European eels face multiple threats due to habitat destruction, fragmentation, and degradation. The construction of weirs and dams is one of the major factors that negatively impacts eels. It restricts their movement and blocks both upstream and downstream migration routes, destroying and fragmenting their habitat. As a migratory species, freedom of movement is crucial for their survival, making the presence of these barriers a significant concern. Additionally, global warming and ocean modifications further degrade eels’ habitats, affecting the survival of larvae during their drift and silver (adult) eels during their spawning migration. Furthermore, the introduction of nonnative species and the increasing contamination levels in eel habitats also contribute to their degradation, posing another danger to the species’ survival. Overall, European eels are a landmark opportunity to highlight the diverse range of causes of habitat loss and the (slow) violence ingrained in it.
