Tonight, Saturday March 27th, from 8:30-9:30 is Earth Hour. For those who have not yet heard of this event, I will fill you in. Every year, on the same date, people all around the globe turn their lights off for one hour. Last year hundreds of millions of people took part in the third Earth Hour. It is meant to be a global call to action for everyone on this planet, and it raises awareness on topics like climate change. It is such a simple campaign to become involved with, and it only takes one hour out of your year! So, make sure to flick off the switch at 8:30 tonight.
