(Human) Nature vs. Technology

Then why the need for a good fertility doctor?

So we know there's some sort of natural phenomena on the island, some sort of healing /geomagnetic energies. My thought is this: what once was pure is now tainted. Before anyone discovered the island (during the time of the four-toed statue), there was an indigenous society living in harmony with the natural tendencies of the island.

But the island has changed. The indigenous people have been wiped out. The Hanso Foundation (along with the help of Widmore Labs), worked on ways to profit from the island, trying to find ways to harvest the natural health benefits, trying to find what made it tick, thinking that if they found the answers to Shangri-La, they could find the answers to the world's problems. But somehow it went too far, the natural energies were f**ked with, and we now have unnatural side-effects.

The incident.
The need for a smoke monster.
The need for the swan to regulate a fluctuating and dangerous geomagnetic field.
The need for quarantine and a vaccine.
The need for a spinal surgeon.
The need for a fertility doctor.
