The October 2014 Greenpeace USA Photo of the Month by Callahan Chittagong Tuttle shows the start of the Ice Ride event in Phitsanulok, one of the oldest cities in Thailand.

Over 1200 people took to the streets in Phitsanulok in a ride, led by Phitsanulok bike club, Greenpeace supporters, and the Climate Action Network (CAN) Thailand. The group stretched for 30 kilometers and along the way, bikers stopped at Naraesuan Bridge to unveil a 12 x 2.2-metre banner.
One of many images documenting similar events in 30 countries around the world, I like this image for the way it captures some of the 1,200 bicyclists who took part in a ride that stretched over 30 kms (18.6 miles). I like the blue of the riders and the big Save the Arctic Banner set off with the orange banner at front and the white polar bear costume at the front of the crowd.
I like bicycles so the photos of kids, families and people of all ages in creative costumes, face paint and Save the Arctic t-shirts riding together in some of the worlds iconic locations to support saving the fragile but incredibly beautiful Arctic from industrial development are wonderful. From right here in Washington, D.C., to Chile to Toronto, from the Philippines to London, Bangladesh, and dozens of cities in Europe, people came out to support a future for the Arctic that is free of risky oil drilling, mining and industrial fishing.
If we can save the Arctic, we just might save ourselves – one bicycle ride at a time.
