Effects of Environmental Change on Species Diversity

Purpose: The aim of the study is to assess the effects of environmental changes on species diversity Methodology: This study adopted a desktop methodology. This study used secondary data from which include review of existing literature from already published studies and reports that was easily accessed through online journals and libraries Findings: The study found that environmental changes, such as deforestation, habitat fragmentation, and urbanization, lead to a decline in species diversity. Climate change has emerged as a critical driver of changes in species diversity. Rising temperatures, altered precipitation patterns, and sea-level rise have caused shifts in species distributions, changes in community composition, and reductions in species richness. Pollution including water and air pollution, has detrimental effects on species diversity especially in aquatic ecosystems. Unique Contribution to Theory, Practice and Policy: The study was anchored on the theory of island biogeography which was propounded by Robert MacArthur and E. O. Wilson and niche theory which was originally proposed by G.E. Hutchinson. The study recommended that conservation efforts should prioritize habitat preservation and restoration. Protecting and restoring natural habitats is crucial for maintaining species diversity. Conservation practices should focus on minimizing habitat loss, creating ecological corridors, and rehabilitating degraded habitats. Environmental policies and regulations should be designed to mitigate the drivers of environmental change and promote sustainable practices.
