It is possible that everyone can participate in Earth Day. Of course, participation can take many forms. Some are active, and those activities may require a great amount of physical activity. Other activities are passive, and those activities take little physical effort.
In 2019 Earth Day is April 22. The first step in participation is planning. In the days before Earth Day decide how you will participate. Even if you become aware after the actual date, it will not be too late to do something. The idea that Earth Day is a single day on the calendar is wrong thinking. If Earth Day is to be effective in changing the ecology, actions must persist long after Earth Day comes to a close.
