Studies have shown that light pollution may damage the bat's vector behavior and thus affect the regeneration of tropical rain forests. Every year, large areas of tropical rainforests are cleared or converted into agricultural land. The team said that when soil fertility declines, the land is often abandoned. Natural succession of wasteland will lead to the loss of biodiversity, and the speed of natural afforestation is very slow. They added that fruit bats can help rainforest plants replant their land and act as seeds for spreading seeds. In natural dark conditions, bats produce a rich seed rain. However, artificial light at night may prevent bats from spreading seeds. We equipped with advance automatic screen printing machine, inkjet
screen making machine, autowashing & heatsetting machine which allow
us to make the Flag size up to 2*6 meters with 7 colors. Our factory
occupy the area of 3000 square meters, employ about 200 works,provide
the production daily capacity for 12000 ~15000 square meters. To protect
the environment,we also build the water recycling system according to
the standard of national environment protection.
With the reputation of products quality and creditability since
settled, we have made the project of supplying flags for: the 10th
national Games of china, the world table-tennis Championships, 2004
Athens Olympic games, 2008 Euro-Championships, 2008 Beijing Olympic
Games and Vancouver 2010 White Olympic Games.
As a leading manufactory certificated by ISO9001 in china,we are known
as the best quality, the reasonable price, and the fastest delivery. Now
our products already exported to all around world ,such as:Germany ,
Sweden , Switzerland, Belgium, Iceland ,Canada, Australia

The researchers found that facing a man-made fruit bat in Costa Rica faced artificial light would avoid foraging. According to the research team, light pollution may have a negative impact on the ecosystem based on research results and calls for the establishment of a lightless shelter. 
To test this idea, the researchers studied how the short-tailed bats in Sowell ingested food. The research results show that light pollution may have adverse effects on forest regeneration in the tropics. Daniel Lewanzik, co-author of the Leibniz Institute, explained: "In tropical habitats, bats are more effective than other species in their use. Changing the lighting design or creating dark corridors for photosensitive species can reduce light pollution."
