Final answer:
The 'extinction thesis' in environmental ethics concerns the loss of species and essentially their evolutionary history, emphasizing the importance of biodiversity conservation. Essentialism relates to this concept as it posits species have essential characteristics that are lost forever with their extinction. The field of conservation has evolved to appreciate the intrinsic value of biodiversity beyond human-centric perspectives.
Step-by-step explanation:
The Extinction Thesis and Its Relation to Essentialism
The so-called "extinction thesis" refers to a concept in conservation biology and environmental ethics that addresses the loss of species and the subsequent loss of evolutionary history.
This concept highlights the significance of preserving biodiversity not just for its ecological value but also for its contribution to Earth's evolutionary legacy.
Extinction represents the end point for a species' unique genetic heritage, which, once lost, cannot be recovered. Therefore, extinction risk is a critical issue in conservation science, as summed up by researchers like Stuart L. Pimm and Clinton N. Jenkins.
Essentialism in biological terms generally alludes to the idea that each living species has a set of essential characteristics that define its identity.
It can relate to the extinction thesis in the sense that the irrevocable loss of a species due to extinction also means the loss of its essential qualities and the unique role it might play within an ecosystem.
The intersection between these concepts is crucial in debates about conservation priorities and the ethical considerations that guide them.
For instance, extinction driven by human behavior, such as habitat destruction, not only terminates the existence of a species but also the intrinsic value ascribed to it by essentialist views.
Nevertheless, the conservation ethics have evolved from a human-centered perspective wherein other species and natural environments were considered predominantly as resources for human use.
The progressive amalgamation of ecology, evolutionary biology, and related sciences has informed a more holistic approach to conservation, which acknowledges the importance of protecting the vast biodiversity and the interdependent nature of life on Earth.
