Imagining what our cities will look like in the future has long been a favourite pastime of the Hollywood movie industry.
Many of world's big cities are surrounded by shanty towns. On the whole we are presented with striking images of glass and metallic towering structures, flying cars and technologically smart everything.
Ask a gathering of leading thinkers in the worlds of architecture and design, and you get a rather different picture
Some 70 million people a year migrate from the country to cities. That is about 130 a minute, says Robert Neuwirth, author of Shadow Cities.
Many of these set up home in squats, put together from scarce materials, if put together at all. There are a billion squatters in 2005. By 2050, that figure will reach three billion.
At this rate, our future cities may turn out to be quasi-temporary, low-tech shacks, missing the basics of human life, such as water and electricity, still belching out the waste of fuels that warm the globe.
Globalisation has done its best to push constant migration deeper into the urban from the rural with the promise of work.
Internationally renowned designer, sustainability architect and author of Cradle to Cradle, William McDonough, argues that we can only think of our future cities if we think about what our intention is as a species.
The question for designers of what is dubbed the Next City is how to love all species all the time.
Mr McDonough's ideas for the Next City are about to be played out in China where his company has been charged with building seven entirely new cities.
"In the 70s we saw the hegemony of fossil fuels. So what would be the next design philosophy we would want to work with?"
He looks at the Next Cities as objects of human artifice. They can grow, they can breath, and they can be ecologically sound, just as trees, forests, and gardens are.
They can use energy, expel waste, and reproduce in ways that nature intended without destroying everything else around them.
"In biology, growth is good. If we could do something where growth is good, that would be a way of thinking of a good operating system for design," he says.
"We lay the city out so everyone can move in parks without crossing traffic, the buildings have daylight lighting, the university is at the centre, and with hi-tech connectivity."
The buildings and all around it work like biological, growing beings, photosynthesising and producing and re-using their own energy.
Waste is energy in Mr McDonough's Next City vision; methane is used to cook food. A quarter of the city's cooking will be done with gas from sewerage.
"The energy systems will be solar energy. China will be largest solar manufacturer in the world," says McDonough.
To top the Next City in McDonough's thinking, the soil will be moved onto the roofs. The city will be inhabited by species and the top of the city will be green.
His approach to city design may be the stuff of some people's eco-science fiction novel. But it shows that cities can change - humans can change the way they do things.
But, he says, the Stone Age did not end because humans ran out of stones. It ended because it was time for a re-think about how we live.
In the UK, the Spread of out-of-town superstores halted.
Outlining the latest survey on shopping trends at a London conference organised by the Town and Country Planning Association, John Prescott, the deputy prime minister, said "big box" retailers, such as the Swedish furniture chain Ikea, were changing course and considering smaller town centre outlets.

"They've joined Asda and Tesco and Sainsbury's, and the housebuilders and the office developers, and realised that we mean it when we say we want stores in town and not out on the bypass," he said.
Recalling that the number of out-of-town stores had risen from just 150 in 1979 to more than 1,000 in 1997, Mr Prescott said there was now clear evidence of trends reversing.
However, he acknowledged concern that locally owned shops could be put out of business by the big supermarkets.
"I know that the big retailers can put pressure on local stores, and we have to be aware of this, but which is worse: the major retailers leaving the towns completely or having the big retailers trading downtown, bringing in more money and more people into the town centre as a whole?"
Planning policy, which had put few obstacles in the way of out-of-town shopping, was reversed by John Gummer, the former Tory environment secretary, more than 10 years ago. But the trend continued because many big projects, such as the Bluewater centre near Dartford in Kent, were already in the pipeline after being approved by local councils.
