Answer 1

To complete the flow chart showing how changes in the environment affect migration, the best response would likely be:

Drought, dust, and wind destroyed farmlands.

This response clearly reflects a negative environmental change that can directly lead to migration, as people may need to leave affected areas in search of better living conditions or more arable land.

The other options describe responses or solutions to the environmental changes rather than the direct cause of migration itself.
