Below is a photo of the low cost fence that is being built on the Sand's organic farm.
The point of the fence is to contain the livestock (still to come) in an affordable manner and it also acts as a pest barrier (especially for grass hoppers). In the long run we will plant along the bottom of the fence where the rain water caught in the bottles slowly drips.
Huge numbers of plastic bottles have been collected over the past year from a number of locations up and down the beach. The clear bottles are separated into piles of the same brand and shapes, the bottoms are removed (to be used later) and the bottles are then stacked along plastic string before being hung on a single strand of binding wire which is supported on rough Neem Tree poles.
Total cost? The roll of wire, the fuel for collection and the salaries of the sustainability team.
