Optimization: Adjusting something to reach its best state for a specific purpose. We often think that the fastest and strongest options are the best. The fastest way down a slope isn’t a straight line, but a parabola that naturally connects high and low points. A sniper can cause more lethal wounds at 400 meters than at 200 meters. Although the bullet travels faster at 200 meters, the wound size isn’t as large, and at 400 meters, the slower-moving bullet over a longer distance causes more friction as it passes through the wound, resulting in more severe injuries. In every situation, there is an optimal choice suited to the goal. Trial and error are useful for finding this optimization. - 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”
