Gareth, I certainly understand you live in a very crappy part of the world; it wouldn't surprise me the least to see the conditions you mention. However, wringing one's hands, wondering "what can we do", throwing them up in the air and shrugging it off (ie, passing the buck to the future) - does nobody any good. Unfortunately, that is the way it seems things are handled by our species in a great part of the world, which is pitiful - and ultimately may prove the death of us unless better education on the importance of a clean environment to our worldwide health and longevity takes hold (of course, someone will say "none of this matters with the extreme poverty and lack of food - etc", which is true, to a point - the fact is, its all inter-related; its a network, with network effects - no one part is responsible or helps when fixed by itself; all parts must in a strong position, or none are).
