The development of sustainable systems will and should take time. This is work that cannot and should not be rushed as we are developing patterns which our children and possibly our children’s children will have to live with. Reference within the Park’s statement to "ample time" and in particular the policy of three years of temporary permission will in the future be seen to be hindering sustainable development. As David Holmgren (co-founder of Permaculture design with Bill Mollison) said when he taught here in 1994,

On similar lines, to tie ourselves down to a design and stick to it despite all else is like trying to swim with one hand tied behind our back; as Monty Roberts says,

"It is good to have a plan but don’t fall in love with it."

Natural systems evolve and adapt to changing conditions and so too should our designs. It is lack of understanding to criticise us for being flexible and adaptive, as made clear in the following;

"The philosophy behind permaculture is one of working with, rather than against, nature; of protracted and thoughtful observation rather than protracted and thoughtless action; of looking at systems in all their functions, rather than asking only one yield of them; and of allowing systems to demonstrate their own evolutions."
