Campaigner Greta Thunberg was back with her Fridays for Future strike today, encouraging youngsters everywhere to march.

The 18-year-old joined a demonstration in Berlin, Germany earlier as voters prepared to head to the polls in a federal election at the weekend.

She wanted green issues to be front and centre on the package given to the electorate by parties vying for their vote. And she was keen to make the demonstrators’ voices heard.

So, what exactly is the Fridays for Future strike? Where have campaigners been making their opinions known? And what are they aiming to achieve? Here’s what we know.

What are the Fridays for Future strikes?

The Fridays for Future strikes began in August 2018 when 15-year-old activist Greta Thunberg walked out from her classes and began demonstrating for climate action.

That spurred her on to protest every day outside the Swedish Parliament in the run-up to the country’s election, hoping to encourage politicians to act on climate change.

After being alone, Greta had other youngsters join her, and they committed to carrying out the action until politicians agreed to policies in line with the Paris Agreement.

Soon her local movement turned into an international awakening, and Greta spearheaded demonstrations across the world, encouraging people to take to their national parliaments and council buildings to call for greater action on climate change.

Where have the Fridays for Future campaigners been making their voices heard?

The Fridays for Future strikes have been taking place across the globe. Today’s action has seen climate activists descend on Lisbon, Portugal and Cape Town, South Africa.

Some have been taking part in the UK too with activists on the streets in Glasgow, Sheffield, South Yorkshire and the capital, London.

What are the Fridays for Future strikes hoping to achieve?

The people taking part in the Fridays for Future strikes hope to be able to change the course of history when it comes to climate change so future generations aren’t hampered by it.

On their website , they say: “The good news is that scientists believe limiting warming is absolutely technically possible. With renewable energy technologies, changes in farming and transport, and other big changes, we can limit warming and avoid even worse outcomes.

“Scientists have modeled these pathways to a better future in detail, we simply need our leaders to embrace them. Scientists have been demanding this for 50 years and haven’t been listened to, and that is why we are taking to the streets. Non-violent protesting is an effective way to bring change.”
