There is a tightly guarded secret that many major cities do not want to get out: The air their citizens breathe is steadily becoming more toxic, by the day, due to their burgeoning populations and all that goes with that when it comes to the environment. My city, Austin, Texas, has begun experiencing what the TV weather folks call "morning fog." In reality, one has to only step outside and take a whiff to know that this fog is actually SMOG! It smells rank, it burns your throat and eyes. One can only guess what it does to your lungs! I need to say that I've been here for forty-three years. This "morning fog" is a new thing. Austin gets over 5,000 people moving here, net growth, monthly. Everywhere, sky cranes fill the skies, everywhere, huge apartment complexes pop up in a few months time. Those folks moving here bring their vehicles. We have some of the worst traffic in the world! Exhaust fumes fill our air. As construction does away with permeable ground cover which can provide a certain level of natural filtration for surface runoff, our streams and lakes are becoming cesspools. Dog owners are warned not to let their pets swim in Lady Bird Lake, downtown. Several dogs have died after doing so. Point is, the true state of Austin's air quality is not publicized. I have called on the Chief Meteorologist of the most popular TV station, here, to give daily composition breakdowns on our smog. He has ignored my entreaties, thus far. Last night, there was a news piece, on national news, about the wealthier folks, in certain large towns, who are choosing to leave for smaller towns, for health concerns. Make no mistake about this: This phenomenon is only the small snowball starting down the snowy slope. I predict that in the next five to ten years, major cities will see a mass exodus of their more affluent populations. When this happens, tax bases will collapse, cities will try to stay solvent by gouging poorer folks with massive tax debt, and, when that fails, new ghost towns will come into existence. I'm not sure our generation has to sweat this. In the near, or not so near future, we won't be around to deal with this. However, for those of us with "grown kids" and grandkids, I would counsel that they should be advised to carefully choose where they plan to move and raise their families, in view of the above.
