Landscape architecture is a wide swath of design opportunities combined into one profession. Everything from small residential landscapes to the redesign of 5000 acres of land to creating plans that maintain and save natural systems is within the realm of landscape architecture. This vast design experience is why I love the profession; that, and I get to try to save the world one project at a time.

Wikipedia.com says:

"Landscape architecture is the art, planning, design, management, preservation and rehabilitation of the land and the design of human-made constructs. The scope of the profession includes architectural design, site planning, housing estate development, environmental restoration, town or urban planning, urban design, parks and recreation planning, regional planning, Landscape Urbanism, and historic preservation.
