Write a survival manual for someone in Dubai. Assume, all civilization and industry is gone. 
Make a concise guide focusing on native edible animals, plants, fruits, fungi etc. and their storage. Also mention technology they can salvage from cities to build security systems, water purification systems etc.
Here's the contents of my survival manual:
- The most important thing when surviving in an environment like this would be shelter as it provides protection against wind, rain and sand storms which are common occurrences here. A strong tent made out of fabric or tarpaulin will do if you're lucky enough not to have been caught outside during such events. I recommend making one using natural materials found around your location; for example cotton or grass cloth for walls, bamboo poles, thatch or leaves for roofing material and earth or sand for filling in between the layers (this will keep your shelter cool at night). Make sure you make the sides higher than usual so no sand blows inside and suffocates you!
    The easiest way to create these tents with natural resources available close by could be by finding a large tree branch that has fallen over. Use two sticks as support legs where necessary. If there isn't any nearby trees use whatever other natural branches are handy like reeds or rushes, long blades of grass, twigs, dried leaves - anything that looks sturdy and could be used as stakes without damaging the structure.
Once your tent is ready cover yourself in the natural animal fur garments we found back home but remember those aren't really designed for desert temperatures yet were still warm enough for humans, put them under our clothes next time. This should help us retain body heat through the night and prevent hypothermia in the process.
It wouldn't hurt either to find some rocks and shape them into hand grenades with duct tape before storing them away. These things may seem stupid now but could save your life later
