10 MAY 2016 - BAN KHANA, TA TUM, SURIN, THAILAND: Water buffalo walk down the main road in the village of Ban Khana, near the Cambodian border in Surin province, Thailand. Water buffalo used to be the main &quot;beast of burden&quot; for Thai farmers but now most Thai farmers use tractors and buffalo are kept as a source of meat.      PHOTO BY JACK KURTZ
