Anyone who thinks that this is a good way to draw attention to the issue is off their fucking head.
Lets face it, everyone has heard the term "climate change" and had it shoved down their throats for years. Doing nothing but sit in the street while disrupting people achieves absolutely nothing, apart from pushing away every day Australians from your cause.
You want to help, then lead by example ffs. Get off your fancy phone, your computer, ipad, laptop etc, ride your pushy everywhere, no car trips, holidays requiring plane rides etc. Then try and come up with your own ideas on how to combat climate change.
Dont just sit in the middle of the street like a fucking bum and expect everyone else to fix it for you.
