What are direct benefits of biodiversity?
Direct benefits relate to consumption, including food and medicine
These are tangible products that can be harvested from ecosystems.
Why is the biodiversity of food crops important?
The biodiversity of food crops is important because:
* We need to preserve old varieties for future needs
* We need genetic diversity for crop survival
* Pests and diseases can wipe out non-resistant strains
* Breeders require wild strains for resistant genes
Genetic diversity helps ensure food security.
