Natural disasters like drought, flood, and wildfire can significantly impact living organisms by altering their environments. Drought dries up habitats by depleting water sources like rivers and lakes and desiccating soil. Floods inundate land under heavy rain, washing away plants, soil, and destroying animal habitats. Wildfires fueled by drought conditions can ravage forests and other lands. These environmental changes caused by disasters threaten organisms by degrading or destroying the resources and shelter they rely on to survive.
