fracking, that basically means banning the drilling method that is currently most used to get natural gas and oil out of american sites, anyway. >> right it depends on who you ask. some say ban fracking totally, some say ban it on public lands. paul: how many want to ban it totally? >> most of them want to do that. amy klobuchar said she will look at it case by case. the contradiction is they're talking about climate change as if it's an existential there. they're talking about it in terms of mobilization to world war ii. that seems to demand some solutions like natural gas which is a clean transition fuel or nuclear power that they're ruling out. or even just lifestyle changes. one of the most compelling moments for me in the climate debate or town hall was many of the candidates were asked do americans need to change their diets, cattle, there's a lot of carbon emissions from that and they basically said no.
