The last step is action, which means mobilizing humans to participate in the process of seeking a human-nature harmony. To achieve this aim, Andy repeats the art work at different locations, showing that if more people join in the action, more grounds can be protected from rain, which is actually symbolizing the concern towards environmental issues. Most of his work is done in the suburban areas of a city such as St. Abbs, Scotland in United Kingdom which aims at bringing back urban dwellers to nature. The repeated creation of this art work is appreciated as it draws the attention of more audience so the effect of raising public awareness towards environmental issues is bigger.
