Threats to Biodiversity

27.4K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

What is Conservation Biology?

24.6K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations

17.5K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Biodiversity and Human Values

17.5K
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Genetic Drift03:33

Genetic Drift

44.4K
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.

    Summary

    De-extinction, like reviving the mammoth, challenges traditional conservation goals. It doesn't fit efficiency or necessity rationales, prompting a re-evaluation of its conservation value.

    Area of Science:

    • Conservation Biology
    • Ecosystem Management
    • Genomics

    Background:

    • De-extinction projects focus on long-extinct species (e.g., passenger pigeon, thylacine, mammoth).
    • Novel conservation strategies are often justified by efficiency and necessity.

    Purpose of the Study:

    • To analyze de-extinction within existing conservation rationales.
    • To question the inherent value of de-extinction as a conservation goal.

    Main Methods:

    • Conceptual analysis of de-extinction's alignment with conservation principles.
    • Examination of efficiency and necessity as justifications for conservation technologies.

    Main Results:

    • De-extinction does not align with the efficiency rationale of improving existing conservation efforts.

  • De-extinction's focus on reconstituting absent species differs from maintaining extant ones.

    • Conclusions:

    • The social and ethical assessment of de-extinction requires more than evaluating its means.
    • The worthiness of de-extinction as a conservation objective itself needs critical examination.
