Countries in sub-Sahara Africa have long suffered over creeping encroachment of the desert and the burden on those able to grow crops and sustain wildlife to feed more of their countrymen. The new climate that will emerge in the Aftertime will bring cloudy days, almost without letup, and a foggy drizzle that will do less to encourage the vegetation in the area than encourage rot. Bugs will flourish, and survivors of the shit, who will be many as they will primarily be out in the open for the great quakes and free from volcanic ash fallout, will cast about for a new diet. Bugs will be pursued by rodents and frogs and birds who will be pursued by snakes, and varieties not familiar to the survivors, but migrants. Thus the challenge will be to sort out what is edible, what is poisonous, and what makes for a balanced diet.
