This eTwinning project is connected with water and ecology. Water makes up a majority of your body weight and is involved in many important functions. This includes flushing out waste from your body, regulating your body temperature, and helping your brain function.Water is very important in our daily lives. We use water in many ways. Water is used for drinking, preparing food, washing hands and clothes. When we take a shower we use water too. Water is also used for agriculture and fish farming. When we grow crops or fish, water is required because plants and fish need water to grow and survive. Water is widely used for generating electricity. This year’s World Maritime Day will be celebrated on 28 September 2023. Why is water so important in our life? 1. It helps create saliva. 2. It regulates your body temperature. 3.
