The document discusses the concept of sustainable development as it relates to the lifestyle of inhabitants in Calabar, Nigeria. It notes that while some ways of life are harmless, others are potentially dangerous to natural systems. It evaluates several aspects of life in Calabar: agriculture is not sustainable as only a few engage in it; transportation is not sustainable due to many individual vehicles; energy is not sustainable as residents prefer firewood; conservation of endangered primates is sustainable; and waste disposal is sustainable. The author's opinion is that government policies need development and enforcement, alternative transportation explored, alternative clean energy promoted, and public education on sustainable development intensified to improve sustainability.
