       | Well... you _can_ , by providing enough litter bins that people
       | don't have to hold a cigarette butt or a dog-poo bag for half a
       | kilometer or more. Unfortunately, since litter bins cost money to
       | operate, most cities don't put up enough.
       | 
       | For toilets, it's the same. Public, free-of-charge toilets are an
       | absolute rarity... and politicians whine all the time about
       | people just relieving themselves on the next bush.

       | so that's saying it's somewhere between 8 and 20 cents currently

       | A Swedish startup is training wild crows to pick up cigarette
       | butts and other small pieces of litter. Their method will soon be
       | ready for testing in the city of Sodertalje. The wild crows can
       | be trained through a step-by-step learning process. The birds can
       | learn to pick up litter by placing it in to a machine which
       | dispenses food.
       | 
       | "They're wild birds taking part on a voluntary basis," said
       | Christian Gunther-Hanssen, founder of the company behind the
       | method, Corvid Cleaning, to Swedish newswire TT.
       | 
       | The company chose to use crows as they are the most intelligent
       | bird, Gunther-Hanssen told TT.
       | 
       | "They are easier to teach and there is also a higher chance of
       | them learning from each other. At the same time, there's a lower
       | risk of them mistakenly eating any rubbish," he said.
       | 
       | Over a billion cigarette butts are left on Sweden's streets each
       | year, and they represent 62 percent of all litter, according to
       | the Keep Sweden Tidy Foundation.
       | 
       | Now, the method is ready for large-scale testing. A potential
       | pilot project is being investigated in Sodertalje municipality,
       | where crows will help pick up litter.
       | 
       | "It depends on whether we can find a place in Sodertalje which
       | will work with the food dispenser, and then if there are
       | opportunities for financing," Tomas Thernstrom, waste strategist
       | at Sodertalje municipality, told TT.
       | 
       | Similar schemes have been trialled in other countries in the
       | past, such as this story from 2018 about crows helping to keep a
       | French theme park clean and tidy.
       | 
       | Gunther-Hanssen believes that the scheme could save the
       | municipality at least 75% of costs involved with picking up
       | cigarette butts, depending on how many the crows collect.
       | 
       | "The estimation for the cost of picking up cigarette butts today
       | is around 80 ore or more per cigarette butt, some say 2 kronor.
       | If the crows pick up cigarette butts, this would maybe be 20 ore
       | per cigarette butt. The saving for the municipality depends on
       | how many cigarette butts the crows pick up".
       | 
       | If the pilot project works in Sodertalje municipality, the hope
       | is that the results could end in a permanent solution which could
       | be used in the rest of the country to complement current cleaning
       | solutions.
       | 
       | If it's possible, they would like to get going this spring,
       | Thernstrom said.
       | 
       | "It would be interesting to see if this could work in other
       | environments as well. Also from the perspective that we can teach
       | crows to pick up cigarette butts but we can't teach people not to
       | throw them on the ground. That's an interesting thought," said
       | Thernstrom.
