Biophilia refers to the innate human tendency to seek connections with nature and other living things, according to the Merriam-Webster dictionary and Psychology Today. It's the idea that humans have an inherent affinity for the natural world, influencing our mental health, hobbies, and living spaces. The term was popularized by Edward O. Wilson in his book "Biophilia". 

Key aspects of biophilia:

Innate connection:

Biophilia suggests that humans are biologically predisposed to connect with nature, not just a learned preference. 

Positive impact:

Studies show that interacting with nature can lead to improved mental and physical well-being, including reduced stress and enhanced learning. 

Applications:

The concept of biophilia is applied in various fields, including architecture (biophilic design), healthcare, and urban planning to create spaces that promote human-nature interaction. 

Evolutionary basis:

Some researchers believe biophilia has an evolutionary basis, suggesting that our connection with nature is rooted in our survival and development as a species.
