No Added Harm

We are very concerned that the 420,000 SeaTac Airport flights are harming the environment, climate and risking the health of our beloved children, families, and workers. SeaTac Airport knows of these concerns. They still want to serve the increase in flights from 47 to 66 million passengers (a 40% increase), the doubling of international flights, and the tripling of air cargo. This is unjust.
