Fear...will occur...her knowledge, psychological harm.
In other words this woman has been psychologically damaged by continued assault by an alarmist press and alarmist political groups that use fear inducing rhetoric to further their agenda.
There is no actual damage that can be pointed to or specific proof that CO2 and/or other greenhouse gases cause the alleged harm to the environment.
Until such proof can be presented the regulations should be shelved.
Laws that impose their own harm on citizens can not be based on supposition and without substantial proof.
The woman should be suing the alarmist instead of trying to impose her will on others.
She was brainwashed by her parents
