London, UK. 15th February, 2019. Thousands of students take part in a YouthStrike4Climate for Climate Day. After gathering in Parliament Square, students used sit-down and roaming protests to block streets around Westminster for around an hour. Strike events involving schools all over the UK were organised by UK Student Climate Network and the UK Youth Climate Coalition to demand that the Government declare a climate emergency and take positive steps to address the climate crisis, including highlighting the issue as part of the school curriculum, as well as lowering the voting age to 16. In so doing, they were inspired by Swedish teenager Greta Thunberg, who protests every Friday outside the Swedish Parliament in order to urge leaders to tackle climate change.
