Conservation
Muhtasari
Once a species is gone, it is gone forever, and its genes go with it. Conservation is the active effort to stop that happening: to manage forests and fish so they renew themselves, to protect species in danger, and to keep ecosystems working. It is part science, part global cooperation, and increasingly urgent.
In this lesson you will define a sustainable resource, explain why species become endangered or extinct, and describe how we conserve them, from protected areas and captive breeding to seed banks. You will also meet the [Supplement] tools of modern conservation, including fishing quotas, AI and IVF, and the genetic danger that small populations face.
Malengo
- [Core] Outline why organisms become endangered or extinct, including: climate change, habitat destruction, hunting, overharvesting, pollution and introduced species
- [Supplement] Describe how endangered species can be conserved, limited to: (a) monitoring and protecting species and habitats (b) education (c) captive breeding programmes (d) seed banks
