Everyone has some kind of environment they simply can't stand or an environment they would never like to see become a reality for them. It is important in story writing to be able to depict vivid scenes of places that are desolate, barren, or outright wastelands with destruction as the primary element of the scenery. This is the place that is the worst case scenario that we would never want to be in. In some cases this can be the real world, but go a little extra mile and think of an environment that could be worse than the real world.
Writing Exercise: Create a setting that is the least ideal for you. This could be a place with much destruction, it could be a place that exemplifies a fear you have be it a place full of bugs and snakes, or a place that is claustrophobic, tight, and hard to breathe in. Be as descriptive as possible and use the 5 senses of taste, touch, smell, sound, and sight--being vivid as possible to help the readers visualize the scene. If you want to go the extra mile, write it in such a way that the reader feels a sense of discomfort in the setting you create.
Example: It was a fresh day in summer, when suddenly I noticed my skin starting to peel rapidly. Scale upon scale, the skin flaked off and flew away like sheets of dry seaweed. Smoke filled the air like that of a freshly cooked batch of jerky. Piece by piece, the particles of my being and all that was around me dissipated-- turning into a burning mist of particles that mimics the very moment when Big and Little landed in Hiroshima and Nagasaki.
Its so hot, it's starting to get so hard to breath. It smells like I'm in a filed of flowers but there all dead. It's so bright that I can't see where I am. I feel so claustrophobic, I'm in panic mood. I start to feel around and come to find out that I'm in a room. I have no idea what my soundings look like. This is the worst feeling ever the smell of dead flowers is making me sick I might throw up. Then all of a sudden the lights go off and the room turns red with loud sirens. People in dark uniforms rush in and pick me up, a kick and scream and then they give me a shot with something I don't know what but I go limp in there arms. Everything goes black. I don't know where they take me next I think I'm dead.
