Governments? Corporations? Other individuals?
It's good that the issue of climate change is much more prevalent in the news now but I don't really understand the point of the protests unless they are aimed at specific governments or corporations who can make the actual changes (and changes in laws) that are needed.
Surely individuals concerned about climate change are already doing things on personal level to reduce their carbon footprint. Unless whole countries are forced to change their energy usage/discourage population growth and corporations that pollute are actually penalised in a way that will actually make them change their environmental impact, then it all seems a bit amorphous.
