While his colleagues examined the detail of transparency in negotiations and the use of a public park during Monday night’s debate over the company’s lease, Greens councillor George Takacs took a broader view: highlighting the long-term problems with the company’s ‘‘frivolous and unnecessary’’ use of carbon.

‘‘What I think people have failed to grasp, any time the issue of climate change is discussed, is how difficult a challenge it’s going to be to end up with a safe climate for our children and grandchildren,’’ he said.

‘‘I know that each time I’m out there of a weekend and I hear the skydiving planes going over my head, I look up and I keep thinking, if I can keep seeing this happening, I know we’re not going to be serious about solving this problem in reducing emissions.’’

‘‘This is not a necessary activity.’’

Cr Takacs was also angered by the irony of an email sent to him by the company’s chief financial officer, which, in the signature, urged him to ‘‘please consider the environment before printing this email’’.

In an equally impassioned summary, Lord Mayor Gordon Bradbery said he also had concerns over the use of aviation gas in skydiving but believed this may be warranted to save children from ice addiction.

‘‘I have to weigh up the fact that there are kids who are not going to have a future tomorrow or down the track because today they are being consumed by ice and distractions or problems in their lives because they can’t find a job,’’ he said.

‘‘That’s my pain, that’s my ache, that’s my suffering – it is that we have failed a generation and I’m looking for a way that we can engage our kids in a way that means we might have to burn a little bit more gas in the hope of keeping a few more alive.’’
