It`s one of the prime conceits of the chattering classes that children can be taken by teachers or significant adults in the know, to be taught to appreciate nature by urban nature trails and farms, as a green oasis in the midst of urban sprawl.
Benjamin Zephaniah is basically taking the piss out of this middle class knows best mindset associated with an artificial wildness being passed off as the real deal. He shows that any old piece of undisturbed ground can be shown as a shining example of nature in action.
He decries the educationalist agenda of taking common knowledge intellectualizing and estranging it as a professional teaching experience. For the most part, nature isn`t about artificial constructs that big up the self esteem of teachers, but simply letting children loose on any old scrap of land and letting them get down and dirty without their heads being pumped full of academic bullshit.
It tells us all to simply take a walk with open ears, mind and eyes; this is all it takes, without any `teacher` ambling along on sentry duty.
There can be a big problem with over explaining to children, when by simply leaving them alone to shoot the breeze in their own way is preferable and natural.
