Canada's airports, parks, pastures and other plants are now in trouble, and the proliferation of wild geese affects the ecological environment of these places, and it is a major hidden danger for aviation. In abersford, LED helped a lot to solve the problem of goose disaster. Local authorities installed flashing LED lights in Lake Mill Park, which will drive away geese resting in the park at night. In the past, it took a lot of energy and cost to clean up the goose eggs and feces produced by a large number of geese. The goose disaster in 1999 also led to a serious aviation incident in the United States. As an Airbus A320 flew into the geese, both engines of the plane were paralyzed, the plane crashed directly into the Hudson River in New York. But fortunately, all 155 passengers on the plane were rescued.
