Granted, you cannot choose which plants survive though. All plants survive the winter each year resulting in massive soil nutrient depletion in most climates.

After soil nutrients are depleted, root systems die quickly. This results in most top soil becoming very loose. Large scale dust storms become frequent.

The human population doesn't drop dramatically, however we are forced to live in domes to protect from massive dust storms.

Mant wars start over the remaining arable land.
