No idea what you're on about. You said it wasn't simple and I suggested it was. If you want to elaborate on why it's not simple I'll give you a more comprehensive answer.
Did you realise that livestock farting and belching causes more climate change gases than the aviation industry? I'd have thought that would be easier to tackle with genetic modifications.
There are a number of things that could be done about both fuel emissions and cattle emissions, such as a change in our diet. You have pinpointed a big challenge in how to get people to change behaviour. Some of the things that you recommend could help, as others have said we need governments to provide structure and investment to things that individuals can't do by themselves.
One thing we really need to do (and I'm not accusing you of this at all) is crack down on this f***ing attitude that some people have that if you say anything about fixing the environment you're a cvnt, if a child decides to do something about it all the f***ing pricks in the right wing press pile in and try to discredit everything about her, where alt.right cvnts who are so desperate to follow their little death cult they attack every principle of science and intelligence that we rely on to function as a society, and all these petty little cvnts who go 'yeah but some things you do have an impact on the environment and you're not perfect so fuck you, and fuck the environment, and fuck any proposals to try and improve things because I'm just a big spoilt f***ing baby and don't want to change so I'm going to pretend the head of an oil company is the person to listen to about climate change and energy not the 98% of the world's scientists who have data to prove their position and the only reason it's not 100% is because 2% of the scientific community is happy to take money from evil cvnts and watch the world literally f***ing burn.'
