People participate in the second annual International March for Elephants in Washington, DC, on October 4, 2014, calling for a ban on the commercial trade of ivory. Thousands around the world marched Saturday to demand that governments do more to stop illegal trade in slaughtered rhinoceroses and elephants. The protests, organised by a movement of grassroot groups, were held in 136 cities and towns across six continents, from Soweto to San Francisco and Tokyo.
