Awareness is oversimplifying it but it's a necessary first step for any major movement/revolution. What can one hope to achieve if people won't acknowledge the problem? Greta highlighted the importance of climate change to many people around the world, and I'm sure she's a role model to many as well. Many more people are plant based/vegan now compared to 5 years ago. Companies are profit driven so every little change from people makes a difference. It's the power of awareness that can push people to change for their new found beliefs.
