In narratology, focalisation is the perspective through which a narrative is presented, as opposed to an omniscient narrator. [1] Coined by French narrative theorist Gérard Genette, his definition distinguishes between internal focalisation (first-person) and external focalisation (third-person, fixed on the actions of and environments around a character), with zero focalisation representing ...
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms ( biodiversity ) and abiotic properties such as nonliving things like water or soil ...
Conservation-far is the means of protecting nature by separating it and safeguarding it from humans. [29] Means of doing this include the creation of preserves or national parks. They are meant to keep the flora and fauna away from human influence and have become a staple method in the west. Conservation-near however is conservation via connection.
Biodiversity is also known to have an important role in reducing disaster risk and in post-disaster relief and recovery efforts. [167] [168] Biodiversity provides critical support for drug discovery and the availability of medicinal resources.
Therefore, humans should increase biodiversity in human-dominated landscapes. By managing for biodiversity in ways that do not decrease human utility of the system, it is a "win-win" situation for both human use and native biodiversity. The science is based in the ecological foundation of human land-use trends and species-area relationships.
Advocates for further reducing fertility rates, among them Rodolfo Dirzo and Paul R. Ehrlich, argue that this reduction should primarily affect the "overconsuming wealthy and middle classes," with the ultimate goal being to shrink "the scale of the human enterprise" and reverse the "growthmania" which they say threatens biodiversity and the ...
The loss of biodiversity may not directly affect humans, but the indirect effects of losing many species as well as the diversity of ecosystems in general are enormous. When biodiversity is lost, the environment loses many species that perform valuable and unique roles in the ecosystem.
