Arrange the sentences into the correct order.
Put the sentences in the correct order:
- Such episodes illustrate why these frozen archives are increasingly viewed as a form of insurance for global food security.
- When a regional disease wiped out a popular strain of wheat in one documented case, breeders were able to request dormant samples from a seed bank and reintroduce lost genetic resistance within a single growing season.
- Once gathered, seeds are dried to a precise moisture level and stored in sealed containers at sub-zero temperatures, a combination that can keep them viable for decades or even centuries.
- Seed banks were created specifically to guard against this loss by collecting and preserving samples of as many plant varieties as possible.
- Crop diversity is quietly disappearing as farmers worldwide concentrate on a small number of high-yield varieties, leaving many traditional strains vulnerable to extinction.
