Ulrik Winding used to work at the youth centre in Copenhagen, and said the squatters had been there for 24 years. The city council is responsible for the riots, he said. It's a right-wing Christian group that bought it.

Christian Barndorff, the spokesman of a local residents network, said the young people who were evicted hadn't been there for 24 years. There are people who use violent methods, he said and the group christian group had offered them another house, but they refused it. They are spoiled young people.

Ulrk said they were ordinary working people.

Listeth, who also lives in the area, said you can't generalise about the people from the centre. They are not all violent people. She says the young people hadn't refused all the offers made to them and they had been misled by the mayor. She is shocked and disapproves of the violence. Her daughter and her daughter's friend were arrested when they hadn't done anything.

Christan said the demonstrations started peacefully. The police told people to leave the area. They didn't go and were arrested.

Ulrik said there's a lack of justice.

Christian said everything has been done by the book and the activists started the violence. They need to redefine their view of the world.

Listeth said that when you undermine youth and their voices they get into trouble. The mayor has to do something.

AJ - NY writesOdd, isn't it, that the youth house was demolished at the behest of a "Christian" organisation, because it was not good enough for them? It seems that a few Christian ideals and injunctions fell by the wayside there.

On ethanol as an alternative fuel, we heard from Matteus in Brazil, who said he drove an ethanol car because it was more economic and better for the envioronment. He said ethanol creates jobs in the agriculture sector.

Leicester Brown, from the Earth Policy Institute in Washington, said it's better to produce ethanol from sugar cane in Brazil than corn in the US, because it is more energy efficient. He said the US was too far north to grow sugar cane, but the US is now the biggest producer of ethanol, but the Brazilian production would still only satisfy 3 per cent of demand in the US.

But Tom Slunecka, Executive Director of Ethanol Promotion and Information Council, said ethanol was a great solution to the problem.

David in Chicago said it would take too much energy to produce ethanol.

Leicester said that to produce the ethanol to fill the tank of a large SUV would feed one person for a year. He said the demand for corn to produce ethanol has put up the price of flour, leading to demonstraations in Mexico.

yes bio fuels are the answer if a fare trade practice is observed by the us and Europe.

Ethanol cannot solve energy problems. Because it cannot meet the global energy demand.

Katya in Rio called to say ethanol is a very good idea. It's clean and Brazil has the expertise to help people produce it and Brail has lots of land.

Matt in Singapore said that the people in power should be willing to look dispassionately for the right kind of alternative fuel. Ethanol is one one of them, but you need lots of land to produce it.

In reply to a text message Tom said, like ethanol, oil also needs a huge amount of processing before it can be used.

Leicester said ethanol is becoming big business in the US with farming groups promoting it. He said wind energy should be looked at much more seriously.

Lyse, an American in London, said there are a lot of alternatives and people need to know the information. Electric and fuel-cell cars should be made available, along with alternative-fuel cars.

Tom said that more information about ethanol will be made available, but not quickly. People power should be used to convince car makers to produce more alternative-fuel cars.

LEYLAND - USA
Electric cars are the answer. Solar, nuclear and wind energy should be used to produce the electricity needed. Ethenol is better than petroleum products, but they are both bad.

John in Calgary, Canada, said ethanol has been used for decades to prevent fuel from freezing in winter and should be expanded.

Philip in Asheville, North Carolina, asked what he could do locally.

Tom said he should change to an alternative-fuel vehicles.

Stock market: Are the falls a blip or the sign or a crash?

Maher in India said it was a correction, not the sign of a crash, but the markets will fall considerably. In India there is a certain amount of panic.

Martin in Lusaka said on a very poor line that it was a correction.

Hari in India, said it was a correction of sorts and investors will have to go through a little bit of pain, but not too much.

David Gaffen from the World Street Journal in NY said we'll continue seeing some weakness for a few months. In the US we would expect the falls to continue. Ordinary people with an average pension will have to consider how much longer they have got to work before retiring before deciding whether to liquidate their assets.

Claudio in Lisbon Portugal said he was a bit worried about the markets, but could still sleep at night. He says the markets were sometimmes difficult to understand.

Shubado Rao from Yes Bank in Mumbai said it was a correction and there would probably be more corrections in the coming months, but no crash.She said a panic reaction had been created.

David said the markets would recover in a couple of months.

Bill the bankerI've never made anything worth while with shares, I may as well put my 2000 quid on horses. It's Cheltenham next week!

Dan from Lava Hot Springs, Idaho, USA writes:
Our modern economy is based on a THEORY. Manipulations of the elements of this theory have become common practice, and it remains to be seen whether capitalism in its present form is "good" for the WORLD.

Steve in Utah
As a brand new investor I was concerned about how much the Dow Jones grew over the last six months. It was not long ago that reaching 12000 was a dream. However, look how high it went in such a short time. While I'm losing money now, it is nice to know that markets are cooling down so that we have a correction and not a crash.

It is too early to worry about worldwide depression. I believe these stocks are over priced and them losing in value is just a blip in the market.
