Your guest seemed like a nice guy, but I'm not feeling too optimistic given his presentation and the website of his org...well, I wasn't optimistic to begin with, but....basically this society is not prepared for what is coming, and he's right, this situation is not being taken care of. What needs to happen IMO should not be purely focused on individual choices even if we start there.... we need to begin localizing food production, move money out of the large banks, and create local support networks for resistance, then use a general strike to gain leverage to make specific demands of the Govt, including shutting down much of the US military industrial complex, the largest oil consuming entity in the world, and appropriate the funds of that money hog along with money used to spy on and SWAT US citizens to instead go for things like tree planting / habitat restoration, localized food production, reproductive services, and whatever R&D and tech implementation would be considered feasible. This also assumes people are willing to stop having children, which is going to have a greater impact than no meat consumption, and which may become a more popular idea as the crops start to fail. (BTW, not all meats are the same, as chicken is considered to be much more CO2 friendly than beef, but locally produced is also key. ) Anyway, so yeah....see you in the apocalypse. I'm sure you'll make it hilarious!
