At 8:30pm on Saturday 23 March, millions of people around the world will take part on Earth Hour.
Earth Hour is a WWF initiative calling on people and businesses across the globe to turn off all lights for one hour as a call for action on climate change.
Last year, hundreds of millions of people across the world took part in Earth Hour and the event was even observed by astronauts on the International Space Station.
Earth Hour is about showing that through collective action we can all make a difference in the fight against climate change. There are countless small changes people can make to reduce their carbon footprints and it can start with the flick of a switch.
Simple actions like turning off unused lights and making sure TVs aren’t left on standby may sound small but if everyone does it, it can make a big difference.
On 23 March people across the world will take the time to switch off their lights and take positive action to tackle climate change and I hope people across the Lothians will get involved.
