Reasons for Conservation

There are numerous reasons why conservation programs are crucial:

  • Maintaining or increasing biodiversity: This helps ecosystems stay balanced and robust.
  • Reducing extinction: Preserving iconic species and safeguarding biodiversity.
  • Protecting vulnerable ecosystems: Preventing rapid loss due to human activities.
  • Maintaining ecosystem functions: Ensuring processes like nutrient cycling, such as carbon cycling, to mitigate climate change.
  • Resource provision:
    • Food security: Ensuring an adequate food supply for the population.
    • Medicinal resources: Access to plants for natural remedies and pharmaceuticals.
    • Fuel sources: Essential for activities like cooking and heating.
    • Genetic diversity: Preserving wide gene pools and varied genetic material in all species.

Conservation Techniques

  • Certain methods help in preserving biodiversity.
  • Artificial Insemination: Artificial insemination enables the production of a large number of offspring without the need for natural mating.
  • In Vitro Fertilisation: IVF permits the use of gametes with specific alleles to ensure genetic diversity in future generations.
  • Known Alleles: Known alleles refer to specific genetic variants that can be intentionally selected for in breeding programs.

Risks to a Species

  • Reduced Genetic Variation: Diminished genetic diversity makes a species less adaptable to varying environmental conditions.
  • More Susceptible: Species with reduced genetic variation are more prone to negative impacts from environmental shifts.
  • Less Resilient and Risk of Extinction: A species becomes less resilient and faces an increased risk of extinction when genetic diversity is low.
