Thousands of school-children have walked out of lessons to take part in "climate strikes" across the region.
The global climate change protests are thought to be the biggest in history.
Activists of all ages are demanding the Government take the issue of climate change more seriously and have marched through places including Cambridge, Northampton, Ipswich and Norwich.
Norwich city councillor, Jamie Osborn, said: “We need action on climate change and governments aren’t doing enough, fast enough. Everyone can do their bit to tackle this but we need collective action.”
One family who protested in Colchester said: “Our planet is dying and no one is doing anything about it.
"The government say they will do something but there is clearly no change. People like Greta Thunberg are speaking out and nothing happens. We are here today to protest and get our voices heard.”
