More Bristol figures have joined a campaign calling for "the world's first augmented reality zoo" to open in the city.
Bristol Zoological Society, which owns Bristol Zoo Gardens, announced last year that the Clifton site would be sold and the zoo would move into the Wild Place Project, near junction 17 of the M5 in South Gloucestershire.
The society plans to get permission for housing on the Clifton land before selling it — but there is an alternative proposal from the OurWorld Bristol group, which includes former Bristol mayor George Ferguson and broadcaster Prof Alice Roberts.

OurWorld Bristol announced in May its plans for "a fully immersive" zoo experience in Clifton with technology like digital headsets and "an enriched and more accessible city garden" filled with bugs, bees, birds and butterflies.
Now Marti Burgess — a Merchant Venturer, lawyer and the owner of St Pauls nightclub Lakota — has added her name to the campaign.
Environmental consultancy Eunomia's founder Dominic Hogg, Cabot Learning Federation CEO Steve Taylor and Ms Burgess are the three latest names to get behind the scheme.
They and 17 others — including Billy Elliot film director Stephen Daldry and Bristol Old Vic artistic director Tom Morris — have signed an open letter to Bristol Live readers, expressing a wish to "collaborate" with the Zoological Society on its plans.

OurWorld Bristol's project would see visitors "travel in space, time and scale to experience animals in their natural habitat, enter the world of insects or go back millions of years to when dinosaurs roamed the adjacent Downs".
The Zoological Society says its recent review of the site found a new attraction would not be "viable financially or operationally sustainable".
It described the OurWorld proposals as "very ambitious" but questioned whether they could "safeguard the future of Bristol Zoological Society". It says it remains confident its Wild Place plans "should continue to be the focus" for the society.
Here is the open letter from OurWorld Bristol in full:

Dr Justin Morris, chief executive of Bristol Zoological Society, said the 185-year-old charity's decision to move Bristol Zoo followed "an extensive process" to explore options and take independent professional advice.
He said: “We endorse many of the values set out in the letter to Bristol Live — a 'connected, welcoming and inclusive place that represents the best of us'. We too want to 'safeguard the zoo’s future and secure a lasting, inclusive legacy for the whole of our city'.
"Our plan will ensure that Bristol Zoo continues to offer millions more people the opportunity to experience the magic of a new Bristol Zoo, in its new home at the Wild Place Project site."
He denied the site will become a "private residential development", pledging its green space will be enhanced for "greater biodiversity" and public access to the gardens will be considered beyond the existing plans for the Clifton Conservation Hub.
Dr Morris added the 12-acre Bristol Zoo Gardens has been struggling "for many years" with a lack of space, declining visitor numbers and restricted parking.
“On a site of 136 acres the new Bristol Zoo will offer an extraordinary opportunity," he said. "Visitors and animals will be immersed in the natural landscape – the zoo in nature and nature in the zoo.

“However, the new Bristol Zoo will be much more than an exciting visitor destination. Animals will be chosen to ensure that we can achieve the greatest conservation impact.
"Our education and scientific research programmes will grow significantly to form a new conservation campus; and our conservation action in the field, saving wildlife from extinction, will increase at the zoo, in the South West and around the world.
“All of this will build on the existing strength of our network of partners and collaborators, locally and internationally, to deliver our mission of saving wildlife together.
“In order to realise this exciting new vision, we must sell the Clifton site. This decision has not been taken lightly. However, it is vital to safeguard the future of Bristol Zoological Society, and ensure an exciting new beginning for Bristol Zoo.
"Our vision for the Clifton site is very ambitious – to create an exemplar of how much needed homes and public places can be designed to be fit for the future we face. That future requires us to find new and profound relationship with nature.
“We will lead a planning application for a residential-led scheme to redevelop the Bristol Zoo Gardens site given its central and sustainable location in Bristol. Fundamental to the development of a scheme for the site will be the importance of good quality, eco-friendly low-carbon homes, largely in areas where there are already built structures on the site."
He promised the site will be "a remarkable place for a variety of people to live, for nature to thrive, and for Bristolians to continue to enjoy".
Public consultation will start this summer and the society will meet and listen to interested groups including "near neighbours and Clifton residents".

Dr Morris said: “We have received a range of proposals for the site from interested parties. We remain committed to our exciting new strategy and our thoroughly considered plans which have come about following an extensive strategic review last year. It is not clear how the OurWorld proposal will safeguard the future of Bristol Zoological Society.
“The recent appointment of a team of leading architects, designers and heritage experts, led by award-winning Penoyre & Prasad architects, represents the beginning of a conversation to ensure that the future redevelopment of the site is the best it can possibly be for Bristol.
“Bristol Zoo Gardens will remain open until late 2022 and visitors will not see an immediate change while plans are developed further. Wild Place Project will remain open throughout this time, until it becomes the new Bristol Zoo from early 2024.”
