James Field found his love of Africa late in life. After a career with some of the world's largest financial institutions he became a deerstalker and developed a strong interest in wildlife conservation. Then, a decade ago, at a charitable event held to raise money to protect Africa's endangered rhinoceros population, he won an opportunity to visit Southern Africa for the first time. Through his many subsequent visits to explore sub-Saharan Africa as a conservationist and hunter he saw that much more needs to be done to arrest and rebalance the damage that humans are causing to the wildlife and its habitat. Only those who have spent time in Africa can truly appreciate how urgent this need is. He is a freelance writer for a number of UK and International fieldsports publications and lives in Surrey, England.
