This month marks the 40th anniversary of what some consider the birth of the modern environmental movement. On 22 April 1970, 20 million people across the United States participated in an environmental protest modeled after anti-Vietnam War teach-ins. This year, more than a billion people around the world are expected to take part in Earth Day celebrations. Rotary clubs have come up with countless creative ways to get involved; here are some projects to inspire yours:
