There was a man in the jungle
Trying to make ends meet
Found himself one day with an axe in his hand
When a voice said "Buddy can you spare that tree
We gotta save the world - starting with your land"
It was a rock 'n' roll millionaire from the USA
Doing 3 to the gallon in a big white car
And he sang and he sang 'til he polluted the air
And he blew a lot of smoke from a Cuban cigar
Precisely this. I will give examples of US hotels since thats really the only first world country I have visited. Everywhere there's shades and basically with 4/5 lights I get no where near the light that a single no shade light gives in my own room. There are lots of things done in third world that are done in a more polluting matter for cost concern. But I would hazard a guess that if you take a ratio pollution / 'improvement of quality of living' first world countries would be so far ahead of 3rd world countries that there would be no competition. When I said countries I do mean most in that category there are bound to be exceptions.
