@TaroZz, you CAN, very much, make a difference in the world using your skills of art, persuasion and design combined with your concern for animals and nature! In fact, you have hit upon one of my favorite topics. I’m an amateur dabbler, but I also thought about using my artistic inclinations to become a landscape designer when I was young but I was afraid that would just mean designing wealthy people’s yards and I wanted to something more idealistic…
Now I regret not doing it because a whole new fascinating field of sustainable, ecologically-centered design/architecture/gardening has arisen. It focuses on water conservation, design that is least disruptive to the ecosystem, the use of native plants and organic practices to create habitats of native birds, beneficial insects etc.( (replacing the sterile landscapes of exotic plants that don’t create habitats, or at least incorporating some nativie species into traditional plantings.) This kind of design is being implemented around public buildings in cities and towns, in parks, along highways, etc. Progressive ecological designs and practices in wealthy people’s yards can (hopefully) also have a trickle-down effect in encouraging the availability and popularity of native plants around everyone’s home. The use of green roofs in cities is another exciting development.
To start, read anything by Doug Tallamy, including his book Bringing Nature Home and The Living Landscape (along with the photographer Rick Darke.) Dr. Tallamy is professor in the department of Entomology and Wildlife Ecology at the University of Delaware.
Just to begin getting ideas, Google such terms as sustainable landscape architecture/design, use of native plants in landscape design, Urban native gardens, green roofs, etc. Google to find universities that offer sustainable design! Google “Wood Thrush Nurseries” owned by Ian Caton…a landscape designer formerly of the Philadelphia area who now owns a native plant nursery in Virginia. Google the High Line in NYC, an amazing new urban park created on an elevated former freight train track over Manhattan that is now a walkway surrounded by native plants. Google gorgeous “Lurie Garden,” a native prairie garden oasis in downtown Chicago. If these things excite you, you might find your path.
I don’t know off-hand which universities specialize in sustainable/ecological landscape design but I imagine if you search enough on the internet you can find this information! I think most are graduate programs, or bachelors’ that lead to graduate programs. I think you need a combination of coursework in art/design, botany and ecology, and you could likely (but check requirements for any given program!!!) get into a program with an undergraduate degree in any of these (with coursework in all three areas, depending on your emphasis.) If you are thinking about more of an emphasis on the architecture or engineering aspect, you would need a solid math background as well. Good luck to you! Let us know what you think and how it goes! There may be other students who can benefit from this as well.
