There's nothing i can do personally? Thats literally the problem.
People supporting businesses that ruin the environment is the problem. Sure its not our responsibility, the government needs to make changes but until then stop eating animal products, stop flying, driving car etc.
Vote with your wallet, thats the only thing they listen to.
I think corporations' efforts to shift the view of responsibility from a collective goal to an individual one is one of the biggest problems we face. Individual action is almost never as impactful as collective action. While labor is told to take personal responsibility on individual issues, capital works collectively to consolidate power and amass more wealth. Individuals cannot shift that by themselves. "Vote with your wallet" will never lead to the substantial structural changes we desperately need.
Controversial opinion: spend all of your time on activism and none on unilateral sacrifices that won't lead to systemic change. You've only got so much time, money, willpower, etc.
The "carbon footprint" paradigm is designed to exhaust or discredit those who actually care, so that their political impact will be reduced. The moment one suggests that we fix this global prisoner's dilemma, they're labeled a hypocrite by people who don't understand economics.
