The relationship between climate change and freshwater ecosystems is critical as rising temperatures and altered precipitation patterns impact water quality and availability. Changes in hydrology can disrupt species habitats, affecting aquatic biodiversity and disrupting ecological balance. Additionally, climate change can lead to increased evaporation rates and altered runoff patterns, exacerbating water scarcity in many regions. These shifts can also enhance the growth of harmful algal blooms and reduce the oxygen levels in water bodies, impacting fish and other aquatic life. Understanding this relationship is vital for developing effective management strategies aimed at protecting freshwater resources and ecosystems amidst changing climatic conditions.
