On October 15, all kinds of blog writers are urged to write about one topic. They are urged to write about the important topic of Climate Change. This site explains the move better. To quote them:
Blog Action Day is an annual event that unites the world’s bloggers in posting about the same issue on the same day on their own blogs with the aim of sparking discussion around an issue of global importance. Blog Action Day 2009 will be the largest-ever social change event on the web. One day. One issue. Thousands of voices.
With the recent events that has happened in the Philippines, as well as in other countries, I implore all those who own a blog to spread awareness by writing about Climate Change on October 15. May this small act become a spark for people to be more informed and more concerned about Climate Change.
