We consume as little water as possible. Use less water while watering plants (whether filthy or clean water). Avoid drinking water that has been standing for too long because any bacteria in the water will grow more quickly when there's no other choice.
Water is used the least for agriculture. This is because crops need water to live and grow, but they can survive for a few days without food. Most of the time farmers have no choice but to use water for their crops. When a farmer has no other option, they will usually choose to use water wisely by limiting the amount they use per crop and planting multiple crops in one season so they don't run out of water.
Water is used the least for industry. This is because industries can be located far away from where the water comes from, so they often use desalination machines to make fresh water even though this is expensive. Sometimes people try to destroy factories by burning them down or bombing them, but most often these actions lead to polluted water sources because chemicals escape into the air or burn holes in the ground.
Water is used the least for domestic purposes. In fact, only about 5% of all water is consumed by humans. The rest is used by animals or lost through evaporation or other processes.
Water is used to drink, bathe, prepare food, wash dishes, clothing, fruits and vegetables, and clean teeth. Water is also used in medicine to make pills and injections.
People want to know how much water is contained in their body. The amount of water in your body is called your body weight in kilograms (kg) multiplied by 0.611 liters (L). For example, if you weigh 70 kg then you have 41.3 L of water inside you.
The average human being consumes about 1,500 ml (52 oz.) of water a day. This is almost half of your body weight in water! The most common way people lose water is through breathing out vaporized liquid into the atmosphere which will eventually condense into rain or snow. People who exercise heavily may lose water through sweat. Average men sweat about 50 ml (1.9 oz.) per hour while exercising hard and this can add up to 250 ml (9.4 oz.) of water lost per hour.
Your brain is made up of about 60 percent water. Your blood is made up of about 55 percent water. Your muscles and other tissues are made up of about 15 percent water. So, in general, water is used for many important functions in our body.
When we use water to bathe and clean our teeth, we are preventing the spread of additional illnesses. However, many everyday water uses are unnecessary. We use water to clean our vehicles and driveways because they appear better clean. Furthermore, we frequently consume more water than is necessary to do important chores. For example, when shaving, most people need only enough water to form a lather, not the entire reservoir.
The U.S. consumes about 80 billion gallons of water per year, much of it for unnecessary purposes. Alarming trends in the use of water include the growing number of residential water violations issued by environmental agencies, especially during drought years. There have been significant increases in the amount of time that our toilets are left on full blast (5 minutes or more) as well as the number of households with multiple toilets usage (such as a toilet used twice per day). Overuse of water causes flooding, sewage spills, and other problems for residents and businesses across the country. It is essential that we all use water wisely to prevent overloading the water supply system.
Many industries require large amounts of water for their processes. For example, aluminum manufacturers need water that is extremely pure because even small amounts of impurity can cause expensive repairs to production facilities. Pharmaceutical companies also need extremely purified water due to the quality control requirements of the pharmaceutical industry. These industries can often hire contractors to provide water for use at locations away from its source; these contractors are called water brokers.
