Living in cities keeps us apart from nature taking away the experience of life.
It is sad to live the experience of watching how some animals kill others to eat and survive but this is just what they have always been doing and experiencing it, we see the reality and learn to live with it, avoiding it, makes us way more vulnerable.
I remember watching my grandma clean a chicken after coming from the market when I was a child. You would purchase the whole animal, and take home to clean and cook. You could see the head, the legs, some feathers and all the body. Today, when you ask kids to paint a chicken, most of them draw a supermarket plastic tray full of tights as they have never seen one in real life.

Every confort we add to our life, brings us time, but steals knowledge, creativity and self suficiency. It is good to keep some of those hablities with us in the event we ever need to use them.
