The Sahara has experienced significant changes over time due to shifts in climate, vegetation, and human activity. It has gone through periods of desertification and greening, with evidence of past lakes, rivers, and vegetation indicating a more hospitable environment in the past. Today, factors such as climate change, land degradation, and population growth continue to impact the Sahara's landscape.
