I agree with chrono. Everyday should be Earth Day.Not just about the discarding of litter, but the indiscriminate destruction of the planet we live on! Immense tracts of rain forests are destroyed every day; for what purpose? For buildings? Furniture? Railway "sleepers" ?
In these modern times any of the above can be made from Steel,Concrete,or Plastics. I don't mind furniture made from Bamboo; Bamboo grows very fast. But, to chop down a tree! That, to me,is nothing less than sacrilege!
