Describe how freshwater ecosystems face challenges of global climate change. Give an example from the text

What will be an ideal response?


In regions where climate change increases precipitation and stream flow, erosion and flooding could threaten the structure and function of aquatic systems. Where human activities have altered the landscape, flooding could bring increased pollution. In regions where precipitation decreases, water bodies could shrink, affecting organisms in these habitats, as well as human health and well-being. The Maldives are likely to suffer from water-related stresses because their human population is expanding, and rising sea levels are threatening to bring saltwater into the nation's wells. Also, low-lying coastal wetlands, such as the Florida Everglades and Gulf coast marshlands will very likely make a transition either to brackish water ecosystems or even marine ecosystems as seal levels rise.
