Autumn Nicholl, 4, and her brother Theo, 5, were among those who came out in support, with their Mum Fiona Nicholl.
Young Theo had been learning about climate change at his West Spreydon school.
He said he was worried about the “fish dying”, while younger sister Autumn was most concerned about the whales.
They’re preaching doom and gloom to five year olds? I hope not.
No problems with teaching about climate change in secondary school, but telling five year olds that the fish are going to die because of climate change is appalling.
