Final answer:
Landscaping is the term used to describe the design and modification of landscape features for aesthetic or practical purposes, requiring knowledge of art, design, and biology.
Step-by-step explanation:
The term used to describe the art, business, or protection of designing, arranging, or modifying the features of a landscape for aesthetic or practical reasons is landscaping. This field encompasses a wide range of activities, from the ornamental arrangement of flower beds and fountains in royal castles and historic houses, to the layout of vast public spaces like Central Park in New York City, to the planning of entire city designs, such as Pierre L'Enfant's plan for Washington D.C. Landscape designers must be knowledgeable not only in art and design principles but also in the biology of plants to create sustainable and aesthetically pleasing environments.
Even historically, figures like Thomas Jefferson at Monticello illustrated a passion for botany alongside their pursuit of classical landscape design. Today, landscape designers are also involved in the restoration of natural places such as wetlands, which have been encroached upon by human intervention. The work combines elements of psychology, geography, and business to evoke emotional or cognitive responses that align with company or community interests.
