Many food crops are threatened in the long term through the coming likely extinction of their wild relatives.

The way we breed new varieties for desirable traits is by crossing the plants with their wild relatives. When those are gone, this procedure will be impossible.

Local cultivated varieties are in danger too.

The world-wide concentration of agriculture on 12 plant species and 5 animal species is dangerous, because a disease that harms production of any one of them is an automatic disaster.
