On April 22, 2017, our planet will be celebrating its 47th Earth Day. This special event was launched for the first time in 1970. Back then, only a few regions around the world marked the occasion. Today, almost 200 countries will join in consort with the Earth Day Network that features an entire week of activities focused on environmental issues. Since the formal agenda does include some eco-friendly endeavors introduced by pet owners over the years, today I'd like to highlight a few of the successful and meaningful ways you can engage with your pets for Earth Day, 2017.
