There are many arthropods living in the grass of suburban parks, such as snails, earthworms, mantis, long beetles, etc. After work, people often ride bicycles or run on the park roads, accidentally stepping on animals to death, which is bloody and cruel. The newly designed "safe passage" takes advantage of the animal's habit of drilling holes. It is a path made of multiple hard plastics. Snakes can safely reach the other side through arched holes. At the same time, people no longer have to worry about the psychological fear of stepping on snakes at night. The design advocates harmonious coexistence of human beings and animals. Each square brick has an area of 60 square centimeters, and the arched hole is 20cm high and 30cm wide (snakes can swing through). There is a hollow hole on the top of the square brick, and the light can shine into the arched hole to prevent the snake from staying inside.
