Easy answer. It's called government regulation. Specifically the air pollution control act. England enacted similar legislation around the same time after 4000 people died in London after a 4 day fog.

(burning coal?) A related question, if I may? Once upon a time, everyone burned coal in factories, businesses, and homes for heating and cooking. City air quality was often atrocious. There were even some epidemics and mass deaths as a result. I remember my grandparents using coal, at least into the late 1950's. But somehow, it all stopped rather suddenly. I was too young to know why or how this was achieved. What caused the sudden change? And, could that same effect happen again, to bring us to a "tipping point" so encourage a rapid change from coal and oil to cleaner technologies? -- Do the thing that needs to be done, even if no one else yet notices that it needs doing. -- anonymous -- Lee Hart, 814 8th Ave N, Sartell MN 56377, www.sunrise-ev.com _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
