What Is The One Thing We Absolutely Need

What is the one thing we absolutely need?

Since between 50 and 65 percent of our bodies are made up of water, it is vital to our survival. We use water for many vital aspects of our lives in addition to drinking it. Water has always improved earth’s living things. As a result, without water, life is impossible on earth.Water is a necessity for all living things, from tiny cyanobacteria to enormous blue whales. Water is essential to life as we know it. Wherever there is water, life also exists. Water, whether salty or fresh, hot or cold, abundant or scarce, is a necessity for all organisms, including animals and plants.Aside from everything else, the body needs water, food, oxygen, and a healthy nervous system to survive. Without food or water, humans can survive for a short while, but without oxygen or a functioning nervous system, they would perish immediately.

What do people possess but not require?

Body parts and organs that serve little or no function in humans are referred to as vestige. They are an artifact from our ancestors. We have more than a hundred vestige anomalies, the most well-known of which are the appendix, wisdom teeth, coccyx, external ear, and male nipples. Vestigial organs are body parts that once served a purpose but are now largely useless. The appendix is arguably the most well-known example, though it is currently debatable whether or not it is truly rudimentary.
