When automation is used to send out unwanted emails to very many people the total wasted time becomes a significant resource. An 80 year life expectancy is 2,524,608,000 seconds. If it takes just 2 seconds to identify and delete each unwanted email, sending out 631,152,000 unwanted emails, which arrive in inboxes in one sense, is equivalent to killing someone with a life expectancy of another 40 years.

According to http://www.internetworldstats.com/stats.htm 2,781,571,589 people used Internet by end 2011.
