I've been to an interesting conference today, discussing the issues surrounding plastic packaging. There was a really good list of speakers, who had lots of facts and figures about the good and bad of plastic packaging, but the following was the one fact that really stood out for me.
Do you know how long it took the USA to change from a society where 90% of travel was by horse, to a society where it was 90% by car? Can you guess?
12 years!
Imagine what a massive transition that must have been and the change in infrastructure that would have been required. I'm not sure what period it happend, but I would've thought early 20th Century (I could probably look it up on Wikipedia). Obviously there are lots of factors involved; economy, income, supply etc. But it goes to show that massive changes to fundamental aspects of society and culture can take place relatively quickly - if the outcome is attractive or desirable.
And that's the big challenge with climate change... How do you make it attractive (and not just frightening or depressing)?
