Over 4 million people die prematurely from illness attributable to the household air pollution from cooking with solid fuels.that is according the WHO.

Road traffic injuries 1,274845
Suicide 844 460
'the number of war deaths has also plummeted. In the 1950s, there were almost 250 deaths caused by war per million people. Now, there are less than 10 per million' With 7 billion people in the world that would be 70,000 per year.
'437,000 people murdered worldwide in 2012'
The war statistic is a bit misleading as things go be very quiet until a big one kicks off.
Still the idea that instead of sitting around camp fires singing peace protest songs we should sing campfire protest songs was surprising to me.
