2.3.1 Drivers of biodiversity loss
Biodiversity is subjected to numerous forces that threaten the loss of species and the depaupering of natural resources (Brand et al., 2008).
Biodiversity loss drivers (mechanisms that influence the extinction of a species) are generally encompassed in (but are not limited to): environmental stress, large environmental disturbances, extreme environmental conditions, severe limitation of resources, the introduction of non-native species, or geographic isolation (Slingenberg et al., 2009).
The most prevalent manner biodiversity is removed or reduced is extinction. When a species or group becomes extinct it no longer has any known members of that species left on Earth.
When a species becomes endangered or extinct, more than just that species is affected. The disappearance of a single species acts like a ripple in a pond (Slingenberg et al., 2009); spreading through the ecosystem and affecting other species in unexpected ways. In general, species extinction primarily disrupts the food chain, leaving the ecosystem at greater risk for further biodiversity loss.
While natural disasters and extreme ecosystems are naturally occurring, humans cause much of the environmental stress which is a direct driver of biodiversity loss. Habitat change or

However, some argue that larger populations require more land to live on, wealthier populations consume more resources, and advances in certain technologies can lead to a degradation of ecosystems. These factors are thought to help speed up or act as a catalyst to the effects of direct drivers, including habitat loss and overexploitation. Yet, the negative qualities of these indirect drivers of biodiversity loss are not universally accepted; some argue that technological change allows a more efficient use of resources and that cultural belief can impart a conservation ethic (Slingenberg et al.,

    Humans have altered the environment and changed the territory. This exploits the species of that area directly. As a result of the isolation and small size of the island, the ecosystems of the Polynesia-Micronesia hotspots are exceedingly vulnerable to habitat degradation. Due to the threats, species in this hotspot are some of the most endangered in the world and species extinction rates are high, especially for birds and mammals (McGinley, 2011). Humans use animals for food, medicine, building materials, and ornamentation.…

    If a species is pushed out of its natural habitat, or loses it completetly, then it becomes very vulnerable. Olive Heffernan confirms in her article that deforestation is considered a main factor that drive species to extinction. Climate change also leads to loss of habitat. Deserts grow, ice caps melt and the sea level rises, all of which have detrimental consequences to those species reliant on habitats that are affected by those changes. Poaching, for instance rhinos and tigers, pollution of rivers and lakes and overharvesting of the oceans are further causes of species extinction.…

    One example of this is the mass extinction of amphibians. Amphibians are extremely sensitive to environmental changes and for this reason in the past century their extinction rate is 45,000 times its natural rate. Our survival as a species is inextricably linked to the survival of other biodiversity on earth in many ways. For one, mass extinctions can disrupt ecological processes such as pollination leading to many ecosystem…

    According to the article “Living with dams: managing the environmental impacts” written by Matthew McCartney, “The most negative downstream consequence of river regulation caused by dams on mammals and birds is the disruption of the seasonal flood regime along the river” (Nilsson & Dynesius, 1994). How the flooding regime being altered effects the birds and mammals, is the changes in vegetation may place the birds and animals that depend on it at risk. All of these reasons are what makes Dams a concern to our…

    When wastes are not treated this causes major effects on aquatic life. Often than not, dead fish and other aquatic life animals are killed because of the pollutants that attack their habitat. Lead and cadmium are pollutants that are consumed by aquatic animals that often contribute to their death. Not only does pollutants affect aquatic water quality life, but ground water is also affected. The most common sources of contaminants are pesticides, sewage, nutrients, and synthetic organics.…

    If there are no trees to fulfill these imperative responsibilities, countless former forest lands can quickly become arid deserts. Eradicating trees deprives the forest of its shelter, which prevents the sun’s rays during the day and stores in heat at night. This disturbance precedes to more dangerous temperatures swings that can be injurious to plants and animals (“Deforestation: Modern-Day Plague” 2). Loss of habitat can lead to species extinction; this is not only a biodiversity tragedy but also has deleterious consequences for…

    One way is because it destroys their habitats. Animals tend to live in areas that have plant growth, and that is being destroyed by pollution. Poisoning is also hurting animals, because when they get into lakes or rivers that have high levels of pollution it can kill them. Then, another way that pollution affects animals is because it can mess up their migration. When areas are polluted and food is no longer available, they may start to migrate.…

    This happens because the overall potential of the species to adapt to environmental changes becomes eroded by the loss of genetic diversity. More specifically, genetic diversity occurs among higher taxonomic categories, among species, among populations, within populations, and within individuals (Hunter & Gibbs, 2007, pg. 86). In fact, a single species can have a great number of populations that are genetically distinct, which makes microevolution possible, and the loss of even one population of a specific species negatively affects the species as a…
