What weather event is the leading cause of death in the United States?
user
Over 200,000 people die each year due to “astronomical” conditions or air pollution.  These include direct effects of both UV radiation and ozone, as well as smoke pollution, which is considered a significant factor in nearly one-fourth of all deaths in the U.S.  But, surprisingly, only about 13% of all deaths in the U.S. are caused by “natural” disasters like tornadoes or wildfires.

I'm talking about natural disasters.

Are you talking about wildfires, tornadoes, floods, and other environmental phenomena?  Because these represent only about 10% of all deaths in the U.S., and they are far below most other natural disasters, like earthquakes, and more common events like murder and suicide.

I'm sorry, I didn't understand what you were asking about.  Maybe you could use different words?
