There are trucks traveling around NYC announcing that everybody should go indoors because trucks are spraying for west nile virus. It feels very orwellian to hear the trucks go by. Personally the idea of spraying harsh chemicals that could have long term effects all over the environment near millions of people does not on balance make sense. However, the logic of government is you take action in a visible way. If cancer rates increase in 20 years nobody will blame the current administration. Remote risks are on their radar and we get decisions forcibly made for us that we would not make on our own. I would not spray my own yard for fear of West Nile Virus.
