Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population. Low genetic diversity in a population of wild animals and plants leads to a further diminishing gene pool, inbreeding and a weakening immune system and fast tracks that species towards eventual extinction

Deforestation:
- Deforestation leads to the destruction of natural habitats, reducing the genetic diversity of plant and animal species.
- Loss of diverse habitats can result in the extinction of certain species, leading to genetic erosion.
Shifting cultivation:
- Shifting cultivation involves clearing land for agriculture and then moving to a new area after a few years.
- This practice can result in the loss of genetic diversity in crops as only a few varieties are grown repeatedly.
Adoption of genetically uniform varieties of crop:
- The widespread adoption of genetically uniform crop varieties can also contribute to genetic erosion.
- Planting only a few genetically similar varieties increases the risk of susceptibility to diseases and pests, as well as reducing overall genetic diversity.
Overall impact:
- Genetic erosion is a serious concern as it can lead to reduced resilience in crops and animals against environmental changes.
- It can also limit the ability to develop new varieties with desirable traits in the future.
- Therefore, addressing the factors contributing to genetic erosion is crucial for sustainable agriculture and conservation efforts.
