Some air purifiers use catalyzed ultraviolet light to disinfect the air. In oxidative processes with ultraviolet radiation (UV), high quality UV lamps, yield and radiation react with titanium that catalyzes the "burning" of microorganisms, odors and impurities difficult control by the usual systems.
Ultraviolet light eliminates the formation of mold in the air conditioning system, reduces the incidence of viruses and bacteria, preventing their multiplication and disinfects air that passes through the air conditioning system.
Artificial reefs provide shelter, food and other necessary elements for biodiversity and a productive ocean. This in turn creates a rich diversity of marine life, attracting divers and anglers. And states like the program because the increased tourism and commercial fishing benefits local economies.
