Why Earth Day still matters

People around the planet have been recognising Earth Day on April 22nd since 1970. The goal in the beginning was to demonstrate support for environmental protection. And over the years, we have seen more focus on the natural world around us and the attention to issues like global warming. But what difference can one individual make? And how do you keep working at effecting change on something that can seem so overwhelming? Joanna Bull is the Community Engagement Manager with the Ecology Action Centre based in Nova Scotia. She offers her thoughts on staying positive and realistic and shares ways we can make a difference for the planet by thinking globally and acting locally.
