Greta Thunberg organised a 'Youth Strike for Climate' in her native Sweden last year because she realised her generation was going to have to deal with the effects of rapid human-induced climate change, and that many world leaders either refuse to listen, or are not prepared to take action to moderate these effects.
'Climate Strike', put into the vernacular, 'went viral'.
School students all over the world took a day off school to show their solidarity in an attempt to put the issue of climate change front and centre among the threats to their future. Unlike some of our leaders, many senior students do 'get the science' - they understand what is happening to our atmosphere and oceans as the climate warms.
They know that globally, native forests, important carbon sinks, have been drastically reduced.
Locally, many students are aware that the box ironbark forest that once covered a large area of Victoria and NSW has been reduced by at least 70 per cent in 200 years, and that Queensland is clearing its forests even more rapidly.
They also know that Australia, with 0.3 per cent of the world's population produces a disproportionate 1.5 per cent of the world's emissions.
Climate change, and its effect on the environment our children and grandchildren will inherit, will inevitably lead to global disruption, conflict over water and agricultural land, with mass movement of refugees fleeing areas of flood and drought.
