Holly Greenberg is a professor of Art at Syracuse University specializing in printmaking. She's long been aware of how toxic some art materials are, but has recently realized how damaging the mining and production practices are that are used to create these art supplies.

Since that realization, she's committed herself to stop using manufactured art materials. More recently, Holly became aware of invasive plants and has become interested in habitat restoration. In the last year and a half, Holly has begun to create works of art that highlight the importance of creative native plant habitats for other living creatures. Find out more at HollyGreenberg.com.
