Vatten is the Swedish word for "water." It is a vital resource for all living organisms and covers about 71% of the Earth's surface. Water exists in various forms, including liquid, solid (ice), and gas (water vapor). It plays a crucial role in ecosystems, weather patterns, and human activities. In addition to its natural importance, vatten is essential for daily life. It is used for drinking, cooking, sanitation, and agriculture. Access to clean vatten is critical for health and well-being, making it a key focus for environmental and public health initiatives worldwide.
