The earth's ozone layer can block 97-99% of the ultraviolet light from solar radiation. According to the research of the World Health Organization, if the ultraviolet light exceeds the index of 3 or above without proper shielding or sun protection measures, it will cause sunburn and related diseases. Due to the greenhouse effect, the ozone layer hole gradually expands, and the amount of ultraviolet radiation increases, especially in countries and regions located between 30 degrees north and south latitude of the equator.This design will be based on Schuster Park in Queensland, Australia at 26 degrees south latitude. The building envelops and fiber optic tubes are filled with green fluorescent proteins; the size of the module opening and closing will be adjusted according to the absorption rate of ultraviolet light and can emit light at night. This design aims to solve the harm caused by excessive ultraviolet radiation.
