What conservation is
- Conservation is protecting species and habitats, and using resources sustainably.
- A sustainable 可持续 resource is used in a way that doesn't run out or destroy the environment.

Deforestation harms; the others conserve.
Conservation methods
- Protected areas (national parks, reserves) keep habitats safe.
- Captive breeding 圈养繁殖 in zoos, seed banks 种子库, and laws against hunting protect species.
A sustainable resource is one that:

Sustainable use balances present and future needs.
A fishing quota helps keep a fishery sustainable.
Difficulty 1/5 · 100 coins + a small bonus on first completion today
Limiting the catch lets fish stocks replace themselves.
Sustainable resources
- Replanting forests, fishing quotas 配额, and recycling keep resources available.
- The aim is to meet today's needs without harming the future.
Worked example. A fishing quota limits how many fish can be caught, so enough remain to breed and replace the catch. The fishery stays productive year after year — a sustainable resource.
You've got it
- conservation protects species and habitats and uses resources sustainably
- methods: protected areas, captive breeding, seed banks, laws, recycling
- a sustainable resource (e.g. quota-managed fishing) doesn't run out
Write from a seed bank and a quota
- Seeds of rare crops are stored in cold, dry conditions.
- A fishery allows only a set mass of fish to be caught.
What kind of conservation is the seed store, and when is the fishery sustainable?
Saving seeds and limiting the catch are both conservation.
Storing seeds of rare plants in a seed bank is an example of what?
