These water molecules on the earth today have existed for hundreds of millions of years. We may be drinking the urine of dinosaurs. The water on the earth will neither appear nor disappear without reason.
Another book, The Future of Water: A Starting Look Ahead, written by Steve Maxwell and Scott Yates, points out more clearly that dinosaurs drank the same water as us. Fossil energy will disappear after burning, but water can be recycled continuously.
Most of the water on our planet is salt water, which is stored in the ocean. About half of the remaining fresh water exists in the form of glaciers, the other half in the form of groundwater, and only a very small part is stored in lakes, rivers, soil and the atmosphere. Moreover, only this very small part can be used by the creatures living on the earth.
The water in different reservoirs on the earth can flow continuously. For example, the river water flows into the lake, and the water in the lake can seep into the soil. In short, the water in these reservoirs can circulate periodically. In other words, the water that those terrestrial animals drink in their stomachs will eventually be discharged into nature again. So you drink water and dinosaurs have also drunk it. It's also right to think about it. Before the emergence of human beings, the water on the earth had circulated in the body of dinosaurs for several times.
The water we drink
How much dinosaur urine is there?
It is true that human beings consume a lot of water every day, but compared with the former overlord of the earth - dinosaurs, our impact on the water on the earth in space and time is unlikely to reach the level that dinosaurs once achieved. The Mesozoic era, known as the age of dinosaurs, lasted 186 million years, and the earliest ancient ape talent appeared seven million years ago. In theory, before the emergence of human beings, the water on the earth had circulated in the body of dinosaurs for several times.
The discussion about drinking water and water reuse often involves the water cycle. Journalists and scientists like to draw some overly simple or even incorrect diagrams to express the process of water cycle. The core concept is that the water on the earth today is the same as that of dinosaurs.
A large number of biological, physical and chemical processes will continuously create new water. Therefore, water can be seen as continuously updated.
For example, the glass of water on your desk is constantly ionized and decomposed into hydrogen ions and hydroxide ions. Once water becomes ionic, it is no longer a water molecule.
However, these ions will eventually generate new water molecules. If a water molecule is regenerated immediately after being decomposed, we can also say that it is still the same water.
So whether we drink dinosaur urine or not depends on your understanding. It can be said that it has been drunk or not.
