Why does California's water problem affect people outside the state?

California's water problem affects people outside the state due to its significant role in national agriculture, particularly in producing fruits, vegetables, and nuts. Water shortages can lead to reduced crop yields, impacting food prices and availability across the country. Additionally, California's economic activities, including its vast agricultural output, have ripple effects on national supply chains, affecting consumers and businesses nationwide. Lastly, water scarcity can drive migration and environmental changes that influence neighboring states and regions.
