Did you know that 25 million people in the Southwestern US rely on Lake Mead for freshwater? Sophie Shrand of @sciencewithsophie explains how this human-made reservoir, which is a result of the Hoover Dam and generates 1.3 kilowatts of hydropower annually, is under threat due to the climate crisis. The reservoir is currently at 27% of its total capacity, which spells trouble for those who depend on this valuable resource. She reminds us that climate change isn’t just a future problem - it’s affecting us in the present day.
