Nearly 40 pupils took part in a climate strike at Builth Wells on Friday morning, as part of a week of climate change action worldwide.
The two hour event was open to everyone that wished to join in and encouraged adults to join the young people who took time off from their school work to participate.
The demonstration was organised by 15-year-old Elin Bolland, from Crossgates, who is a pupil at Ysgol Calon Cymru's Builth Wells campus.
She sent out an invitation for others to support the event in the town.
She added: "The effects of climate change will soon be irreversible and at the moment are causing extinction for a number of species globally as well as worldwide flooding. It’s likely that my generation will die because of climate change - but we have the power to stop this, if we act now.
"It’s estimated there are over 150 countries climate striking off school and work worldwide this Friday and were last Friday too!
"It’s really important to me that this protest is completely peaceful and positive."
