The march, from St Brigid's Catholic Church to Victoria Park, is being organised by Shirley Colless.

The 78-year-old is well-known for her involvement with the Uniting Church in Dubbo and as a member of the Knitting Nannas Against Coal Seam Gas who run a weekly information stand at the Cyril Flood Rotunda.

Ms Colless wants people of all ages and interests to participate in a "colourful, creative and family-friendly" event.

"On the last weekend in November, world leaders will be gathering in Paris on the eve of the United Nations Climate Summit," she said.

"Across the globe millions of people will be gathering in cities and regional centres to create the biggest climate march the world has ever seen.

"Marches have been organised in major centres throughout Australia and Dubbo will be very much a part of the action in NSW, along with other regional centres including Coonabarabran, Orange, Tamworth, Wagga Wagga and Armidale.

"I invite and urge people in Dubbo and the surrounding area to turn out with banners and placards as the Sunday afternoon march moves along Brisbane and Church streets, past the St Brigid's, Holy Trinity and Uniting churches and on to Victoria Park.

"I would like to see church and general community groups participating, along with individuals, families and friends who care about what is happening in terms of our climate.

"Something has to be done globally because climate change is a big problem. It cannot be ignored or denied."

Ms Colless said she was organising the march because of her commitment, not just as a Christian but as a human being.

"I have had a long involvement with environmental and social justice issues, working to protect recreational areas and the coastal environmental during my years as a councillor with North Sydney Council and organising peaceful anti-nuclear marches in Sydney during the 1980s," she said.

"I regard myself as a peaceful person but there are times when it is necessary to speak out and do something.

"I want humanity to continue with decency, honesty, justice and mercy and peacefulness.

"So much is threatened by climate change and globalisation. Peacefulness in the world is tied up with policy and aggression and reaction to aggression.

"For me protesting needs to be apolitical. I want people to focus on issues like justice and mercy without getting tied up in party politics.

"I accept and understand that not everyone believes in climate change but the scientific evidence is indisputable.

"I sincerely believe that a large part of the problem we are facing at the moment is human induced. The structure of industry, society and the whole economy is having a catastrophic affect on climate.

"I agree that climate has always changed but the current rate of change is not natural, nor are the alarming extremes of climate."

Ms Colless believes climate change is "very much linked" with environmental destruction, dating back to the beginning of the industrial revolution.

"The amount of fossil fuels that have been burnt through the production of iron and steel and electricity and the use of motor cars has been an accumulative thing that has taken several centuries to build up," she said.

"It is not something that happened yesterday.

"The fact is that so much of what we do is based on money derived from fossil fuel extraction in some way, shape or form.

"I would like to see policies put in place to shift the globe away from fossil fuels and towards renewable energy.

"Change is possible to achieve. We saw that when the motor car industry took over from horse and carriage industries.

"Cart, wagon and sulky builders went out of business along with harness makers, the Cobb and Co transportation company and country hotels and shanties.

"Now we have the opportunity to ease our way out of total dependence on fossil fuel industries by developing solar and wind power.

"People keep saying that solar is too expensive and will never replace base load (power).

"But solar is becoming much less expensive and presents an opportunity for creative innovation.

"We are never going to move forward if financial backing continues to be tied up with old industries instead of taking a punt on new industries."

Ms Colless has seen a lot change in her lifetime, particularly in expectations of what constitutes a good standard of living.

"We expect too much and want it all now," she said.

"Credit has become far too easy to obtain and that has encouraged people to want luxury, despite the fact they are paying through the nose for it.

"We need to rethink who we are and where we are going.

"In spite of our 'higher standard of living' there are increasing numbers of homeless and people battling to deal with debt because of the credit that was freely and generously offered and they were foolish enough to take.

"The disparity in society is becoming more and more extreme.

"As people around the world mobilise on climate change on November 29 we need to think about what we are doing to our world.

"Climate change affects the air we breathe, the water we need to drink, the food we need to eat. Nobody is excluded from the need for those things."
