A NINE-YEAR-OLD boy has convinced his headteacher to hold an 'electricity-free day' at school amid his concerns about the climate crisis. 

Contentious Harley Smith, who attends Balksbury School in Andover, penned the letter after learning about the impact electricity usage has on the environment. 

And his writing skills paid off as he convinced Katy Thompson, the headmaster, to hold a day with no electricity usage later this year. 

"I think it is a really important thing to do because the polar bears are losing their environments as well as other animals," Harley told the Advertiser.

He added: "It makes me really sad to see all the awful things happening so I wanted to do something to help at school with my friends." 

Ms Thompson said it would be the perfect opportunity for children to put their studies into practice. 

Harley's teacher Helaina Maclaren will be calling on his help to organise the event which will take place on May 22.  

The year four teacher said: "I'm so proud of Harley. It's clear that this is a hobby of his which he is really passionate about.

"I didn't even know he'd done it [written the letter] until it was announced in assembly.

"The children are very excited. They can't wait to get outside and learn, all thanks to his idea." 

Harley's mother, Jackie Smith, said: "I'm just so proud of him. I think it's a massive achievement for a nine-year-old, he has always been interested in the outdoors.

"We've noticed he's been watching the news a lot more since the fires started in Australia and he's such a sensitive young boy, you can tell it really worries him." 

The electric-free day will take place at the primary school on May 22.
