- A sustainable 可持续 resource is used in a way that doesn't run out or destroy the environment.
Plastic pollution is a major human impact on ecosystems
Which are conservation methods? (Select all that apply.)
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.
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
