From 1580 to 2013 there have been recorded 14 shark attacks in India, 5 of them fatal (the last one was in 1956). Therefore, sharks represent infinitely smaller danger to humans than mosquitoes or ants.
Swimming is a very important survival skill: Tamil Nadu recorded 1837 drowning deaths in lakes, swimming pools, rivers and beaches in 2011.
In the USA, only 10% of drownings take place in seawater. A swimming pool is 14 times more likely than a motorvehicle to be involved in the death of a child age 4 and under. (Orange County California Fire Authority). An estimated 5,000 children ages 14 and under are hospitalized due to unintentional drowning-related incidents each year; 15 percent die in the hospital and as many as 20 percent suffer severe, permanent neurological disability. (National Safety Council and Foundation for Aquatic Injury Prevention). 19 percent of drowning deaths involving children occur in public pools with certified lifeguards present. 58 percent of parents do not consider drowning a threat to their children.
