'EVERY little helps the environment' is the motto of a Runcorn eco-warrior, who is launching her latest crusade against abandoned shopping trolleys on the Castlefields estate.
Nancy Wallwork, of Woodland Walk, is frustrated at the number of Tesco trolleys she sees every day dumped in the Castlefields reservoir and scattered throughout the estate.
Nancy is well known for her enviro campaigns to improve the Castlefields area, which have included making the roads safer, creating a play area for children and cleaning up Bluebell Woods.
Nancy has even had her efforts recognised by the Queen and was among those congratulated for community work in a Buckingham Palace ceremony in 2004.
Speaking about her latest target, Nancy said: 'I found 10 Tesco trolleys scattered round the Town Park one Sunday.
'I've even challenged Tesco a couple of times and spoken to someone at head office, but nothing has really been done about it.'
Nancy thinks the Tesco outlet at Halton Lea is the major source of the problem, but has also spotted a few trolleys from the nearby Asda store in West Lane.
Nancy said: 'I just don't understand why people are taking them, except out of pure laziness. I guess some people are riding them home so that they don't have to pay for a taxi!
'It really is damaging to the environment.'
Apart from making the area an eyesore, the trolleys cause potential damage to animals.
The reservoir at Castlefields is known as a haven for wildlife and includes many species that could be at risk.
Nancy added: 'I don't understand why Tesco's doesn't do more about it. Each trolley must cost about £200-£300, and if just 10 trolleys are taken then that makes a loss of £2,000-£3,000.'
Tesco spokeswoman Deborah Watson said: 'All stores are linked to trolley hotlines so that customers can contact us about any trolleys they see abandoned and we also operate a collection service so we can get them back.
'We know that customers do feel the need sometimes to remove them from our stores and we try to work with the council to get trolleys back.
'We are concerned about the effects on the environment and want to ensure that the trolleys are outside the stores so that they are there for our customers.'
