Not all college memories come from sitting in a classroom or pulling all-nighters in the library. Some of the best ones come from spending time in nature and immersing oneself in their surroundings. There are a number of reasons why a college may choose to support an arboretum. It is a valuable resource for individuals looking to study diverse plant life or even just those looking for a peaceful corner of campus. The benefits of an arboretum aren't just for humans. They also play a significant role in conservation and preservation. Just as zoos are vital for educating people about animals, arboretums educate about protecting the biological diversity of our planet. Green spaces are vital for helping people feel physically, spiritually and emotionally healthy. They allow for individuals to connect with nature and the environment around them which leads to feeling less stressed and much more grounded.
