Seventeen-year-old Lachie Nicholls of St Peter's Anglican College is excited to host a climate change forum on Thursday, May 16.
Lachie, along with a panel of climate experts, will lead the evening discussion at his Broulee school.
Lachie became passionate about climate change after a recent fishing experience in the Snowy Mountains.
"In the first 15 years of my life, the impacts of climate change were never a great concern to me," he said.
"I'm a pretty keen powder skier and, when the snow melts, I dust my fly fishing set-up off and try my luck at some trout in a few alpine streams.
I believe in tackling climate change without removing peoples freedoms.Lachie Nicholls, 17
"I have been fishing up there since I was 10, and the previous summer was 100 percent the worst summer of fishing I have ever had."
Lachie decided to research the alpine climate and trout environment.

"When I talked about it with some friends, they said they had seen fish drifting dead downstream," he said.
"I decided to do some of my own research.
"I am concerned because there is a chance in 50 years, things (will) become non-existent and it would be horrible," he said.
Lachie said his concern for climate change grew as he became aware of rising temperatures.
He will share his message at the forum and hopes people will leave and give more thought to their vote in the federal election.
"I want to see individual action, not just political action," he said.
"It doesn't have to be in legislation, it can be something simple you do yourself.

"I believe in tackling climate change without removing people's freedoms," Lachie said.
"The evening isn't just me ranting.
"It will consider many other aspects of climate change and will aim to cover as much as possible regarding taking action and prevention.
"You will be given the opportunity to raise your concerns and I welcome absolutely any background or opinion."
The Climate Conundrum begins at 6.30pm and the panel includes Emeritus Professor Will Steffen who is the executive director of the Australian National University Climate Change Institute, former Anglican bishop of the Diocese of Canberra and Goulburn George Browning and marine biologist Dr Pia Winberg.
