I like the mechanic, but I can see the bushes having certain limits, they can foresee their demise, but some things are vague, some things are bold. Storms, volcanoes, etc, they can see coming. More incidental things are harder for them to foresee. Go to Comment
One of the things discussed was injecting sulfer dioxide into the upper atmosphere, mimicking the cooling potential of large volcanic eruptions without the actual eruptions. This aerosol plan would conceivably cool the planet several degrees F but no one is seriously pursuing it because terraforming and geoengineering are somewhere between taboo and science fiction.

Seeing as parapsy abilities are rooted in spiritual trauma, it could lead that the presence of EMS and its symptoms could aggravate the situation. The people in the towers are cleaner, more insulated, and more complacent, while the people in the sprawl and undercity are being irradiated as well oppressed. That works nicely. Go to Comment
As the PCs travel the road, right after a bend they hear a sharp whistle and call: "Heeey, not so lazy, move your asses!" It is a large man that calls, and there are unwilling workers that listen. A small company, 10-15 men work on the road, push boulders aside, dig up roots from under the road, etc. The large man that shouted turns to you, smiles fast and mutters something under his breath, sounds like cursing some lazy worker. "Where does the road bring you from, travellers?" And does a little small-talk.
And what is really happening? A group of bandits is 'adapting' the road for shady purposes. The road will not be wider, but tighter, with enough cover around (and a few traps perhaps), and will become an ideal spot for ambushing travellers or entire caravans. The bandit leader wants them all to appear harmless. The 'lazy worker' he cursed was actually a guard that should give warning before any travellers come around (fallen asleep). Not surprisingly, the boss may decide for an ambush even now.
