Of course, adopting a cool, eco-friendly lifestyle is a year round thing, but there are a few days in particular where many people stop and pay attention to these kinds of issues. Coming up soon is Earth Day, celebrated in the US and also in some places worldwide. But it’s far from the only time we stop and take stock of the state of the environment.
