#BluePeter has announced the winners of the Blue Peter #Earthshot Competition, which invited children aged 5 – 15 to come up with an idea to help save the planet and be recognised by His Royal Highness, The Prince of Wales’ prestigious Earthshot Prize.   The winners presented their ideas at Speaker's House in the House of Commons in front of Mr Speaker and members of a cross-party Environmental Committee.   Big congratulations to the five winners: • Marni, aged 8 from London, came up with an idea for family forests where a tree is planted for every person in the UK. • Mia, aged 8 from North Yorkshire, wants to stop factory pollution and global warming with an idea to help clean polluted water using algae ponds. • Llewyn, aged 9 from Glasgow, had an idea to invent compostable glasses which allow people to see how much carbon dioxide is in the air and encourage them to make steps to prevent pollution. • Ruby, aged 10 from Devon, entered with an idea to reduce waste with solar powered vans to give people access to refill services. • Annie, aged 12 from Milton Keynes, had an idea to help save coral reefs by supplying them with nutrients and calcium with ‘ocean bursts’, an idea which came from bath bombs.   The ideas are celebrated on Blue Peter at 5pm on Friday 7 February on CBBC and BBC iPlayer.   #cbbc #houseofcommons
