Eliza Armstrong, nine, tells Sky News why she is going to the protest and why adults need to listen to Greta Thunberg.
Hamish and Eliza Armstrong, seven and nine, are going to the climate change protest in Bristol where Greta Thunberg is speaking.
Climate change activist Greta Thunberg is appearing at a protest in Bristol on Friday, where tens of thousands are expected to join her.
Nine-year-old Eliza Armstrong, from Bristol, will be attending with her brother Hamish, seven, friends and parents.
I'm really excited about going to the climate change protest with Greta Thunberg.
I've done some local demonstrations in Bristol before but nothing as fantastic as this - I've been wanting to go for a while and we're making placards to hold up.
I'll definitely see Greta but I don't think I'll be able to meet her unfortunately.
There's going to be so many other kids there, although I'm kind of anxious to see how many people are aware and see how many have decided to come.
It will be amazing to see all the people who have stopped their work to fight against climate change.
I hope Greta's going to do quite a convincing speech so lots of people get what she's trying to do and what her aim is. I hope it's really powerful and that everyone's amazed by her.
I think adults who look down on her are underestimating her.
She's already written lots of books about climate change, but they're still underestimating her and not using what she's done to realise how much she's achieved.
Greta's definitely done the right thing by standing up for climate change and she's proving nobody is too small.
Quite a few of my year are going to the protest, we've been talking about it all week.
It's meant to be raining but the weather isn't going to stop anyone, it would be a bit strange if Greta didn't come because of the weather.
Lots of people have been planning to come it would be silly if they didn't just because of the weather, this is why we're fighting for climate change awareness.
My year, year four, is probably the most aware of climate change at my school.
Maybe because we're the oldest and have an eco-council and we talk a lot about Greta and her actions.
With my parents, I think I've had an influence on them, you try to make them understand.
I've taught them that maybe you should drive a bit less and I've taught them to not buy so much single-use plastic.
When they found out about Greta they stopped using so much plastic and I influenced them to get more recyclable things.
