One of the main reasons why water is so important is that water is median for transferring heat on earth. When our body releases energy, it is released as a form of heat, which the water absorbs almost instantly and evaporate it off of our skin, causing the "cool" sensation. With that being said, water is in our cells in a vacuum called the vacuole. In human, it is mainly to keep our entire body hydrated and clean, but in plants, water is broken down in photosynthesis, which converts carbon dioxide and water into oxygen and energy(carbohydrates). Water also controls our climate weathers. Warm body of water is evaporated, causing high level of wind intensity. For example, the southeastern coast of the US is annually pummeled by hurricanes and tropic storms. Although we would rather live without them, it is a way of balancing the atmosphere. Water is used in photosynthesis by plants, which produce oxygen - this reaction is vital for the earth as the oxygen produced is used by humans to breath Water is used in coal powered electricity stations. The coal is burned which boils the water. The water becomes steam, which turns the turbine, activating the generator, then producing the electricity. Because water can also exist as a vapor it can be stored into the atmosphere and be delivered as rain across the planet. Water makes up 90% of the earth’s atmosphere and the other 20% is land Our bodies are about 60 percent water [source: Mayo Clinic]. Water regulates our body temperature, moves nutrients through our cells, keeps our mucous membranes moist and flushes waste from our bodies. Our lungs are 90 percent water, our brains are 70 percent water and our blood is more than 80 percent water. Simply put, we can't function without it. Most people sweat out about two cups of water per day (0.5 liters). Each day, we also lose a little more than a cup of water (237
