I become a stauncher anti-capitalist every day, since capitalism and its unsustainable and literally impossible aim of infinite growth, and the greed and corruption it encourages, is why climate change is not only happening but also not being treated seriously, and abolishing it is the only hope we have of dealing with the damage climate change will bring and try and minimize it going forward (since its past the point of stopping it entirely).
The whole point of those responsible shifting blame on to individuals who have nothing to do with the decisions that got us here, nor the profits they make, is to get you to the point you're at now - hopelessness which leads to inaction, or desperation that leads to futile action (like banning straws or paying to reduce your "carbon footprint" - a term they made up for this exact purpose, and so on, all of which are there to make sure you're criticising your neighbour for their recycling habits instead of the companies that say they're recycling and get paid to but really send the garbage directly to landfill, or to a developing nation already drowning in western trash).
What you actually need to be is angry and focused, to ensure your anger is aimed at the right people and the systems they uphold that got us here. Those systems are not natural or inevitable or immutable, they are artificially created by and for the benefit of a really small group of humans, a group we could easily be rid of if we actually united to do so.
Off the top of my head - all of Lady Parts, Lydia West as Jill Baxter in It's a Sin, Toni Collette as Muriel and Rachel Griffiths as Rhonda in Muriel's Wedding, Parminder Nagra as Jess in Bend It Like Beckham, Milla Jovovich as Leeloo in The Fifth Element, Natalie Portman as Evey in V for Vendetta
