The first time I met Greta Thunberg was in Plymouth in 2019. We were 15 and 16 years old, doing media appearances together around her sailing to New York for the UN Climate Action Summit, ahead of the Global Climate Strike.
For the first time, politicians were listening to young people's calls for climate justice, and millions of people were joining our strikes. Her voyage was surrounded by excitement and hope, followed in awe by people across the world – we never once needed to question her safety.
