znnw shoes Network May 11 hearing, "a thousand miles begins with a single step." With the pace of human understanding of nature, the increasing variety of shoes, production technology is also evolving. However, due to extensive use of modern shoe-making industry, plastic, chemical raw materials, animal fur, etc., to the great natural and ecological impact. Changes in mode of development is to promote the footwear industry, the inevitable choice to achieve sustainable development. The first shoes are sewn out of primitive people used animal skins, but the number of rare animal skins, making preservation, so relatively rare kind. Oldest shoe is about 3000 BC ancient Egypt's leather sandals. With the development of productive forces, it gradually increased understanding of the nature, shoes material evolving. As early as 3000 years ago in a book of "The Book of Changes" have appeared on the "discharge" and the words "Book of Songs" also have "correct disputes sandals, you can walk on frost" description, where "discharge" and "sandals" are rather crude use of hemp, Ge woven shoes, shows that people have started making shoes with Ma Ge. Such as Ma Ge drawn wider, the less the number of skins advantage, making it easier to shoes, shoes can be used more widely. The invention of cloth shoes ushered in a revolutionary progress, more soft and comfortable cloth shoes, and better thermal performance, and beautiful, soon became popular throughout the world, becoming a wide variety of cloth shoe One of the main materials. Today, GE grass, cloth, represented by natural fiber fabrics and in pigs, cattle, sheep, represented by shoe leather has been the main material. However, it was with crocodiles, snakes, lizards, wild animals such as ostrich leather to footwear, mink, fox fur, also be used as decorative shoes. If the ancient people used animal skins footwear is due to the low levels of productivity had no other choice, some of today's society with a wild animal fur shoe business is to reap huge profits, while the foot pair of shoes made from skins of wild animals who are intended to shows the grandeur. Crocodile enormous size, to swim, to climb landing on Earth has survived 100 million years. Unfortunately, the strong long-durable, beautiful alligator pattern starting from the modern high-end shoe boutique into production materials, and thus become synonymous with high-grade leather. The pursuit of the alligator lead to a large number of crocodile hunting, "the king of reptiles," the rapid decline in the number of survival. According to statistics, the world's existing crocodiles are only 20 kinds. The Earth is the survival of the natural world common home, the extinction of a species would impact the entire ecological chain. Nearly 100 years, global species extinction rate has far exceeded the natural extinction rate, and now every day, many species disappear from the earth. Their extinction will lead to many new drugs that can be used to make molecular attributed to disappear, but also caused many crops will help overcome the harsh climate of the gene attributable to disappear. Shoes of the invention is the production of life from human need to start, but now the pace of human order to go further, it must also protect the natural understanding of nature, to protect our living planet.
