Water in Numbers
Currently, scientists estimate that about 70% of the Earth's surface is covered by water. However, only 1% of this water is suitable for human use. The world's freshwater reserves make up just 3% of the total water volume, and only 1.5% of that is accessible for extraction. The majority of the water (46%) is found in the Pacific Ocean. The Atlantic Ocean contains 30% of all global reserves, the Indian Ocean 20.2%, and the Arctic Ocean 3.8%. The crystallization temperature of seawater into ice is -1.91 degrees Celsius. A glass of water contains up to 8 septillion molecules of H2O. There are more than 1,200 natural types of water on Earth, classified by their properties, composition, and origin.
Amazing Facts About Humans and Water
The human body requires about 1.5-2 liters of regular water per day. Water helps stabilize catabolic processes, contributing to weight loss. Regular drinking fluids suppress feelings of hunger and help eliminate waste from the body. People who regularly consume their recommended amount of water are less prone to heart attacks. Water is vital for humans; without food, a person can survive for 30-40 days, but without water, only 5-6 days. An adult's body consists of 75% water, a child's body is made up of 85%, and an infant's body contains 95%. Over a lifetime, a person consumes an average of 35-40 tons of water. An interesting fact: 34 liters of water can be brought to a boil within 24 hours using the energy from the human body.
