How can we build a meaningful relationship with nature

Human-beings are living in increasingly dense and urban living environments. Urban living can offer important efficiency saving benefits but what is that impact on our relationship and understanding of the natural world. If we do not interact with nature, are we likely to understand its importance or act to protect it? I worry that as a result of urbanisation younger generations may loose touch with the deeper value of nature - we cannot love (or protect) that which we don’t know.
