Beauty and the beast

a walk through the lovely judy woods today. 
i picked up thirty plastic bottles and cans and brought them home to recycle. i could of collected more but no more room in the bag i found. the bins are full and in need of emptying but why would anyone keep adding to the pile. 
i will never understand why people visit a beauty spot to enjoy the surrounding and leave it a mess. when did the keep britain tidy message get forgotten ?
