Droughts are extended periods of time with significantly below-average levels of rainfall, leading to water scarcity. This lack of water can have severe impacts on ecosystems, such as drying up wetlands, reducing stream flow, and causing vegetation to wither and die. Droughts can also lead to wildfires, loss of biodiversity, and disruption of food chains within ecosystems. Overall, droughts can cause long-lasting damage to ecosystems by altering their structure and function.
