Adapting agriculture to a changing climate is likely to depend heavily on the genetic diversity retained in traditional crop varieties and their wild relatives, which harbour traits such as drought tolerance and pest resistance that modern high-yield varieties have often lost through decades of selective breeding for yield alone. Maintaining diverse seed banks, protecting wild relatives of domesticated crops in their natural habitats, and supporting farmer-led conservation of traditional varieties are all measures that expand the genetic toolkit available for future crop breeding.

With reference to the above passage, which of the following would assist agriculture in coping with climate change?

1. Maintaining diverse seed banks.

2. Protecting wild relatives of domesticated crops in their natural habitats.

3. Breeding exclusively for maximum yield regardless of other traits.
