Changing an environment through art

I am interested in creating a topic on the types of modern art created to promote environmental activism. I want to give some examples of these types of art and how they affected peoples' views and lifestyles. I will examine what it takes to create an effective piece of activist art and go over what we can consider actual art. I am thinking of using a social project called ToroLab that is nearby and works on changing the social atmosphere of an area by implanting different biology and new environmental lifestyles/trends.
