Natural environment problems Problems of pollution, resources, population, and the reduction of environmental variety have been considered in detail with an effort to locate suitable cut-off points for nested problems. Emotions such as anger, hate, jealousy, fear, and anxiety have been considered for inclusion as general problems. Structural violence problems Problems relating to any forms of discrimination, imbalance in resource usage, social injustice, or unparticipative decision-making have been considered in detail. In contrast to the previous edition, clearly defined problems of this type have been included. The emphasis has been on problems experienced in practice, not on those that emerge as distinctions in philosophical or theological debate.
