To the south, build the recycle fields and use the available labor to clear and sort.
Bring them in, give them work, house them, feed them, educate them and give them citizenship.

You will be the seeds in the new cities.
We who you see as privileged on this planet, are at your service.
The military will setup the infrastructure and run the day-to-day needs.
The new citizens will supply the workforce to begin building the new city from the ground up.
