Earth science and public health are deeply intertwined. Natural processes like earthquakes and climate change can significantly impact human well-being. Understanding these connections helps us develop strategies to protect communities from environmental hazards and health risks.
Earth scientists play a crucial role in safeguarding public health. They help identify clean water sources, monitor air quality, and create early warning systems for natural disasters. This knowledge is essential for developing policies and interventions that promote healthier, safer living environments.
