Thousands of people are taking to the streets today as park of the largest climate demonstration in history.
Over 2019 young people have been leaving school on certain Fridays to protest about the governments lack of action on the impending climate disaster.
Today they have called on adults to also take part in the strike ahead of the UN Climate Action Summit.
The event in Cardiff is one of more than 200 across the UK and over 3,000 globally.
Though the Welsh Government have already declared a climate emergency and now protesters are demanding that Welsh Government puts in place policy measures to implement a green new deal and make it clear to the public how big the climate crisis is.
They also want the education system reformed to address climate change and loss of nature as an educational priority, alongside a request to include youth voices in policy making and lowering the voting age to 16.
Beth Irving ,17, from Cardiff is one of the organisers of the Cardiff protest. She said: "The young people of the UK striking from school have been praised and called ‘inspirational’ since February, but we need actions to follow words.
"For the first time, adults have stood alongside us to demand an urgent and radical response to a crisis that will destroy homes and displace millions.
"We will no longer be put into the box of 'the children'. We will no longer be brushed aside. Today we stand in unity with all generations to demand climate justice.
"Our current situation calls for what is scientifically necessary, not what is politically possible; we must change the present fossil fuel-based economy into one where equality and sustainability are placed at the heart of society.
"For some, the effects of the climate crisis at already very real: hurricanes in Mozambique, floods in Bangladesh and money-grabbing leaders causing the destruction of our rainforests.
"Climate and ecological breakdown are ticking away while we fixate on party politics. Our message is to say that the time is up and we cannot ignore the alarm any longer."
