Growing a wide range of plant species under optimal conditions

They serve as a conservation method for various plant species.

Question 7

What is the purpose of seed banks?

Answer 7

To store genetic material of plant species

Seeds are kept in controlled environments to ensure their viability for future use.

Question 8

What do captive breeding programs aim to achieve?

Answer 8

Increase the number of endangered species

These programs also focus on reintroducing bred individuals back into the wild.

Question 10

What is the purpose of the Rio Convention on Biological Diversity (CBD)?

Answer 10

To promote sustainable development and protect biodiversity

The CBD was established in 1992 and involves strategies for environmental conservation.

Question 11

What are the three agreements that came from the CBD?

Answer 11

1. Strategies for sustainable development
2. Stabilise greenhouse gas emissions
3. Prevent desertification and reduce drought effects

These agreements aim to address environmental challenges at a global level.
