A Threat To Wildlife And Bio-Diversity Thesis Statement: The acceleration and diversification of human induced disturbances upon natural ecosystems during the past decades has contributed to wildlife habitat fragmentation. The changes in land use have driven wildlife managers to reconsider the benefits previously attributed to the Edge Effects on wildlife diversity. Habitat fragmentation has been recognized as a major threat to the survival of natural populations and to the functioning of ecosystems. The reduction of large continuous habitats to small and isolated remnants affects the abundance and species composition of various Taxa. Some possible factors contributing to this decline include changes in food and cover availability, microclimatic effect, evolution of predation, loss of genetic variation, and lack of recolonization following local extinctions.
There are restrictions to deforesting land and there are organizations to help protect the land. One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct.
This cause disastrous results, and for this reason, rapid habitat loss is the primary cause of species becoming endangered. Nearly every region of earth has been affected by human activity. It is difficult for an individual to recognize the effects that humans have had on specific species (Brook p.385). It is even more difficult to predict human effects on individual species and environments, especially during one lifetime. The introduction of an exotic species into an environment will furthermore cause the endangerment of a species.
More than environmental problems and invasive species, human beings effect plants and animals very much. Humans being the dominant mammal on earth, build houses, take over land, and intrude in different species lands. Taking over land reduces resources for species which automatically effects the species way of gathering resources. Illegal hunting and poaching stays a massive problem throughout the world today. For example, poachers can endanger animals and often eliminate species with their illegal use of hunting (Bove, 2016).
Accepting the doctrine of Animal Rights can result in the extinction of native animals, and also cause adverse effects on the environment. Another consequence of accepting the doctrine of Animal Rights is that humans will no longer be able to control foreign predators (pests) via traps, hunting, fishing and poisons. Many foreign animals have been introduced to different ecosystems over the course of history, and is very likely to have caused many extinctions of indigenous species. This occurs because they compete with native animals for habitat and food, and sometimes introduce new diseases. Maintaining the indigenous species and thus biodiversity is important because animals depend on each other in a food web, and an extinction in one can result in many more following.
In turn, humans interfere and attempt to conquer nature, making it less rural, less wild, and more tame. This makes nature more catered towards human’s needs, what we are used to. To nature, this is a disrupter. Deforestation causes the loss of habitats for millions of species, even those not discovered yet, as well as the acceleration of climate change. Removing the trees leads to temperature shifts, a lack of moisture in the atmosphere, and increased greenhouse gases entering the atmosphere.
Habitat fragmentation has a negative impact on conservation efforts. Habitat fragmentation splits up a population of species of animals with certain barriers such as a roadway or chopping down a forest for new development. When considering conservation, habitat fragmentation makes it anything but an ideal situation due to splitting up the population and always dealing with the unknown of how the species will thrive. Immediate consequences of this process include habitat loss, the formation of remnant habitat patches of varied forms and sizes, a reduction of population sizes, and an increase in the degree of isolation of the remaining populations immersed in an anthropogenic matrix (McGarigal & Cushman 2002; Aguilar 2008). It becomes a an issue
The heat from global warming will also cause pests to multiply fast which will also lead to less crops. Global warming will also make water difficult to give to livestock which will cause dehydration and mass death in livestock population. There will also be an Increase of water temperature harming fisheries and wild seafood population. These impacts can threaten human health through malnutrition, food poisoning, and diseases. There is concern that climate change will have very negative affect on human life and the environment.
Wildlife Endangerment Due to Human Intervention in Nature "The driving force behind today’s alarming decline in species is the destruction, degradation and fragmentation of habitat due to our increasing human population and wasteful consumption of resources. "1 Everyday wildlife is forced to seek refuge in very remote, small areas. As the human population increases, land that was once inhabited by wildlife is urbanized to suit human needs. In other words, the land available for wildlife to survive on keeps diminishing. As houses and roads are constructed, forest are cut down and cleared; consequently eliminating the natural habitats of wildlife.
When humans dump waste products into rivers and streams it endangers the species living in that environment. The waste is considered an abiotic factor, as it is not living. (Hoefnagles, 2012) Other abiotic factors which can alter the sustainability of a species are sunlight, rainfall, terrain, etc. With many developers looking to the rainforest and mountains to build road, railways, and infrastructures, many species are losing their natural habitat and having to seek refuge elsewhere – adapting to new surroundings. The loss of a habitat is a biotic factor, as the habitat is full of plants, animals, insects, etc.
