The Gore thing is egregious because his own fucking film tells people all these ways they can save the earth through more thoughtful consumer choices. It's stupid, yes, since buying a hybrid has nothing on all factories in China -- it's basically the consumerist incorporation of radical environmental ideology. But GORE HIMSELF advocates it and doesn't follow through.
Its dangerous because it gives an easy option, a get out clause which people (and governments) will easily subscribe to- that there is no need to fundamentally alter our lives, our ways of practically living, or systems of political economy. In reality Gore's soft-consumerist/individualistic approach is totally poisonous and deadly to the cause-- creating the illusion that something is being done ("hey I bought a hybrid car, run it on bio-fuel, eat organic-- problem solved muthafucker...") when in reality nothing short of massive socio-economic change and/or technological revolution will suffice.
