‘Ex situ’ approach for conserving biodiversity:
- Ex situ conservation refers to the conservation of species outside their natural habitats. This method is used when in situ conservation is not possible. The main goal is to preserve species by maintaining them in controlled environments.
Examples:
1. Botanical gardens: These are places where plants are grown and conserved outside their natural habitat. They help protect endangered plant species and provide research opportunities.
2. Zoos and aquariums: These institutions house endangered animals in artificial environments and play a crucial role in breeding programs for species at risk of extinction.
Study the pie chart given below, representing the global biodiversity and proportionate number of species of major taxa.
