Heather is in the UK at the moment and cannot discuss conservation, global warming or any topic that is considered green without being shot down by her peers (and family) who see people like us as eco-hippies and all these issues as either hysteria, or a way that Tesco and other supermarkets can charge more for produce that has a green label of sorts (and dubious at that) plastered across it.
Nick I think most folks are busy going about their normal lives that they are in denial and just don't want to hear it as it threatens their little world be it business or lifestyle.
Governments want to keep their people dumb so they go to work and pay their taxes, fill them with football, cricket, fishing, beer or religion, to keep them occupied so they don't think too much about other things. They don't want a population full of smart, deep logical thinking people.
We have folks that are farmers and it did not rain last year so no crop, but they are busy putting in some crop going about their ways as if it's going to be a normal season. It's hard to have a conversation about global warming to them as well. 
Interesting times ahead <_<
