More than 8,000 children are without a green area to play on in central Dublin, according to the Sporting Liberties group.
The group, made up of several sports clubs in the area, have come together to highlight their struggle to access playing pitches.
On Wednesday, the Sporting Liberties group will give a presentation on the lack of facilities for children of Dublin south-west inner city to Dublin City Council officials and other public representatives at Leinster House.
Tom McGee, President of Liberty Saints Rugby, and a founding member of Sporting Liberties, said that without those facilities, young people die, end up in prison or in drug gangs or drug addiction.
Speaking to RTÉ's Drivetime, he said: "That's what happens when you put 8,500 children into an area with no sport and no competitive environment for them to challenge themselves in, at the same time the drug cartels of this world are operating in the same area and it's obvious to most people what would happen," he said.
"I have been at too many funerals to just skip over it on a radio interview, the impact is that young people die. I have been at the funerals," he added.
Mr McGee said: "There are 55,000 people living in Dublin 8, with 8,500 children, ten schools and nowhere for any organised competitive sport to take place."
Mr McGee described the situation as "unbelievable but unfortunately true".
He said they want Dublin City Council to engage with them positively and give them what they need.
He said there is a plot of land, or brown field in development terms, located at the back of St Catherine's Sport Centre in Marrowbone Lane that could accommodate a full sports campus.
"You could put all sorts of facilities in there, but it has been lying idle since 2012, I think.
"It's totally workable, we have done feasibilities, we've done artist drawings and architectural plans, we have done all that, all of the measurements.
"All the research and investigations have been done. It's a shame it hasn't happened by now, but it's clear that it's possible."
Dublin City Council has been contacted for a response.
