Indoor pollution

 

Since the early 80-s of the previous century we have been (1) ……………. about ecology being only too aware of the devastating effects of (2)…………… scale of environmental pollution. Both developing and industrialized countries alike are deplored for their short-sighted, selfish and quite often (3) …………… policies.

And certainly laser printers, computers, carpets and paints don’t (12)………… the situation but only contribute to the noxious indoor mix.



In this context it seems that disproportionate effort is wasted campaigning against certain forms of outdoor pollution, when there is as much or more concern indoors. It’s (13) …………….. to bring a new sense of perspective to the debate about pollution.
