Anthony Wayne Smith, President, National Parks and Conservation Association (NPCA), delivered this address before the Annual Meeting of The Humane Society of the United States, Newport, Rhode Island, October, 1971. Reviewing the philosophy and activities of the NPCA, he discloses how the wildlife preservation movement of the NPCA needs the help of the humane movement to protect wild animals for their own sake, for scientific, aesthetic, and educational purposes, and for the enjoyment and appreciation of people who care for animals. Dangers facing wildlife, endangered plant species, and pressures of a rising human population are also considered as part of man's concern, responsibility, and respect for all life. He must recreate his sense of the community of life, of the interrelationship of all living things. Cooperation between humane and conservation movements for common causes is, therefore, advocated with each lending the other increasing support in the years ahead. To this end man must build up coalitions, submerging individual differences, to cope strongly with environmental matters. (BL)
