Diving into the water without an oxygen tank is called ‘free-diving.’ It is a form of apnea diving in which divers must hold their breath for an extended period while diving deep into the water with just one breath of oxygen. The difficulty in holding the diver’s breath during this time is not due to a lack of oxygen but rather an increase in carbon dioxide concentration. In other words, if you keep your heart rate low and your metabolism slow, you produce less carbon dioxide, which allows you to dive for a longer duration. The only way to maintain a low heart rate is to remain as calm as possible. Maintaining calmness has numerous benefits in life. - Joseph’s “just my thoughts”
Cotton needs 500 mm of water to produce cotton wool, and 1 kg of cotton wool requires 8,500 liters of water to fill 40 baths. A fashion company can make a pair of jeans from this. It needs at least 2,700 liters of water to create a T-shirt. This amount is enough for one person to use as drinking water for three years. Clothing consumption has recently increased by an average of 60% each year on Earth. The Aral Sea in Uzbekistan was the fourth-largest lake in the world, but it has now shrunk to one-tenth of its original size, as river water has been used to grow cotton due to increased consumption. Few people are concerned about how their consumption affects the global environment. - Joseph’s “just my thoughts”
