entirely depends on media and government reaction. depending on the spin in non-mainstream media, people may not believe its nearly as bad as the mass media/scientists portray it
see: climate change still being blown off and cited as a “theory” by certain right wing groups, despite nearly all scientists agreeing it is a real and worrying trend we have to prepare for and curb
no matter how right scientists may be, if the mass populace doesnt believe them, society will forget itself over. unfortunate truth.
