This week we are revisiting our relationship with nature and the effect that it has on our mental health and wellbeing. Finally the rain seems to have stopped and we are enjoying some sunshine. I was reminded of when I was looking out of the window of my apartment in Doha Qatar when I was working at Sidra Hospital. Below me the City was a busy place and I could see at least a thousand houses. Each house full of people, thousands of people. The roads full, sometimes gridlocked, as all these people rushed from somewhere to somewhere else. All in a frenzied dash that is, for many human beings throughout the world, normal everyday life. I was struck by the overwhelming concept of ‘just how many of us human beings are there living on this planet?’
