And I'm Beth.

Many of those leading the fight against climate change are young people who feel betrayed by politicians and adults. In survey after survey, children report feeling that they have no future, that humanity is doomed and that governments are failing to act.

This is causing many young people to feel worried about the state of the planet. There's even a name for it – climate anxiety. And it's also creating conflict between adults and children in families and schools.

What's certain is that a solution to the climate emergency needs the cooperation of everyone, both old and young. So, can talking honestly about the climate help mend the divisions between generations? That's what we'll be discussing in this programme, along with some useful new vocabulary.

But first, I have a question for you, Neil. Many young people's hopes and fears about climate change are symbolised by the Swedish activist Greta Thunberg. These days, Greta travels the world speaking about the climate emergency, but her protests started much smaller in her hometown, Stockholm. So how did Greta Thunberg's climate activism begin? Did she...

a. Plant trees in her school garden, b. Skip school on Fridays, or c. Recycle her school's plastic waste?

Hmm, I think Greta Thunberg went on strike and skipped school on Fridays.

OK, Neil, I will reveal the correct answer later in the programme. One recent survey showed that three-quarters or more of young people in the UK feel the future is frightening.

Here, Immy, aged 14, and Millie, 11, share some of their fears with BBC Ideas.

If climate change were like an animal or a plant, I think it'd be some sort of parasite because it's the only thing that's actually growing and getting bigger while everything else starts dying off. I think climate change is, like, really scary and the fact that lots of people aren't doing much about it just sort of freaks me out.

The environment is definitely very special because if we get rid of it, there's nowhere else we can go. Like, it's a very one-in-a-million sort of planet.

Immy calls climate change a parasite. In the natural world, a parasite is an animal or plant that lives on another living thing and feeds from it. If you describe a person as a parasite, you mean they are lazy and live off other people supporting them or giving them money.

Likewise, Immy thinks climate change is sucking the goodness out of the planet and she uses a slang idiom to describe her feelings – it freaks me out. If something freaks you out, it makes you become very emotional, upset or confused.

Millie agrees. What freaks her out is that governments don't seem to be doing much about the problem. It's not as if we can escape anywhere. Humankind only has one home – planet

Earth. Millie calls Earth one-in-a-million, meaning very special or rare.

So what can be done? Psychotherapist Caroline Hickman has visited ten countries around the world talking to over 100,000 teenagers about their climate fears. They told her about parents ignoring them when they wanted to discuss their feelings and adults telling them, fixing the planet is your job now. Here she gives BBC Ideas some advice on discussing climate change with children.

My advice to adults, parents, teachers is do not put it off, don't push it away, don't save it up and just have that big conversation. Talk about it regularly. That's crucial.

And it's OK for you to say to your children, I don't have all the answers. We're not sure exactly how to deal with all of this, but let's find out together.

Caroline's top tip is to discuss the climate crisis regularly, to talk with children about their climate fears and not put it off – not delay talking about it until later.

Caroline also advises parents not to push it away, to choose to forget about or ignore the subject. A better response is to tell kids honestly – we don't have all the answers but by sharing ideas we can work things out together.

A more hopeful message – and one that's shared by climate champion Greta Thunberg.

Yes, and it's time to reveal the answer to my question. How did Greta Thunberg's climate activism begin, Neil?

I said it was by skipping school on Fridays.

Which was the correct answer. Greta started her School Strike for Climate in August 2018 before it was taken up by over 1.6 million school children from 125 countries around the world. OK, let's recap the vocabulary we've learnt from this programme, starting with climate anxiety – feeling worried, afraid or depressed because of climate change.

A parasite is an animal or plant that feeds off another living thing.

If something makes you feel very emotional or upset, you might say it freaks me out.

The idiom one in a million describes something which is extremely special, rare or unlikely.

And finally, two phrasal verbs to finish with – to put something off, which means to delay doing it till later, and to push something away, which means to decide to forget about or ignore it.
