More efficient flight control and patterns would lower emissions as well as aircraft getting more fuel efficient. This seems to be a big worry but not vehicle emissions as we are trying to pack more and more people into federal way. We need to expand out not up i dont want to be like seattle. Took me almost 20 minutes to go five blocks this afternoon. Its 2017 and airports exist, oh my!  Like i said, emissions are a concern for me also and we can definitely see the difference in certain obvious ways. In some of the major cities around the world people go a short distance and run out of breath. I travel around the state semo regularly and i work out when i do and see an obvious difference in energy and endurance when im in small towns. We dont have to resort to doom and gloom and conspiracy theories to work together. Thanks again Mr Federal way i still love your articles.
