They should all be protected. Not one more roadless acre should be lost to development. To reach these common sense goals we must first recover the moral courage that guided the social revolutions of our past. It was sustained and uncompromising agitation that ended slavery, gave women and Native Americans the right to vote, allowed workers to organize the workplace, established civil rights for African-Americans and lead to the passage of the Wilderness Act. Every one of these struggles was about right and wrong and none was considered feasible by the pundits of their times.
Profit driven abuse of public lands is just as wrong.
It's wrong to carve up the remaining roadless lands. It's wrong to destroy habitat for native wildlife. It's wrong to wipe out the last ancient forests. It's wrong to dewater rivers. It's wrong to graze grasslands to dust.
