Litterati is the name of a company that's trying to make the world a cleaner place and doing a fine job of jye.ai.It has created an app that people can use to upload information about the litter they collect outside，such as its appearance，material and location.Shared online，this information helps to build a global data（數(shù)據(jù)）base of "litter maps"，which can influence government management and packaging design.
   Jeff Kirschner is the inventor of Litterati app.He came up with the idea while walking in a northern California forest with his then four-year-old daughter，who noticed a plastic kitty litter box in a river.Young as she was，she expressed her worries about the box being somewhere that it wasn't supposed to be.This knowledge stays with Kirschner as adults.The litter problem is so huge：what's a single person supposed to do？
   That's where Kirschner thinks an app can help. "Society's failure to solve the litter problem has not been from lacking（缺乏）government support.There have been public service announcements，neighborhood litter walks and coastal cleanups.And these activities successfully raise public knowledge of pollution，"said Kirschner.But he believes one thing is missing from the discussion-online data-and if these are added in，people can start solving the problem in a better way.
   Uploading pictures to an app shows users that they're not the only ones picking up litter from public places.And the data has been gathered rapidly，telling a story that helps people understand who picked up what，where and when. "In San Francisco，the Litterati app was able to discover and map more than 5，000 pieces of rubbish in order to find out how much was produced by cigarettes exactly.Using this information，the city successfully doubled an existing cigarette sales tax（香煙銷售稅）.In the Netherlands，Litterati's data helped push brand Anta Flu to repackage its hard candies in paper，rather than non-recyclable plastic，"said Kirschner.
   Litterati shows a positive we-can-do-it attitude."Its goal isn't to shame.It's to provide a real way to solve the litter problem and encourage people to be part of the project，"explained Kirschner.
