Well the thing is we have an earth that is full of processes of 
combustion.  The little ones people do in vehicles pale in comparison to 
the ones nature does beneath the surface all the time.  And of course 
whenever a volcano errupts we see a mass display of this that of course 
overshadows a billion little tailpipes even.  Average surface area of 
exhaust of .15 ft radius even is 70million square foot of exhaust pipe 
;-).  Which would be a mile and a half x mile and a half hole putting 
away.  The vent size of a typical volcano is..quite  a bit smaller but 
when they errupt it's like an a bomb going off in contrast.  And they 
can continue to spew for quite some time... there are something like 65 
'active' volcanoes at the moment each of which during an erruption and 
in the aftermath will of course make man's contribution to the picture 
look quite insignificant.  NOT to mention these aren't distributed and 
nature has to reconcile the damage in a much more concentrated area 
which isnt' good at all :-)

Anyway we're ranging wildly from the topic but I'm just saying..nature 
is pretty durable because of the broad bandwidth of things it entails.  
If we don't burn the oil...what the heck do people think happens when a 
volcanoe errupts through it? :-)

If we don't build houses out of the trees, what do people think happens 
when a forrest fire takes it all out?

There are some areas where people try to *strain out gnats* basically 
I'm just saying and in the end it looks very foolish indeed.  And the 
ROHS thing has been one of those if there ever was one.  People wonder 
why economies are failing etc. Yet they keep thinking of more and more 
trivial things to plague people's efficiency with.   This human control 
is webbing it's way into all aspects of life.  The food we eat even.  
But anyway... that's all I'll say.  I don't want to plague people 
because it really is pretty off topic in a way except... hey if the 
world government players destroy people's productivity I don't think 
we'll be talking about sdiy stuff much.   People will just be trying to 
survive.
