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”
Eco bags are not eco-friendly. In 2007, the eco-bags, which British designer Anya Hindmarch printed, “I’m Not a Plastic Bag” on canvas, sold out 20,000 copies in 30 minutes at a limited edition price of 5 pounds. The project reduced the use of plastic bags by 58% over the next two years in Britain. However, a survey by the British Environment Agency found that consumers used paper bags at least 3 times more to have less environmental impact than plastic bags and used eco bags 131 times more to help protect the environment. In 2018, Denmark also announced a study that indicated people used plastic bags at least 37 times, paper bags 43 times, and eco bags 7,100 times before being discarded to recover from pollution. Yes, the facts that people believe have cheated us all. Materials and consumption are necessary, but people belatedly realized that environmental protection should also consider product use cycles and production. - Joseph’s “just my thoughts”
