"The riding club undertook horse riding to give the message to the people that if they want to save the earth, they should make all possible efforts to save water and trees," said Achal Chaudhary, chairman, Indore Public School Academy.
The men on horseback rode within a circle of 300 metres, with the riders and the horses taking a break for half-an-hour every three hours.
