I truly dont understand this mindset. The total is always the sum of the components.
You actions make the same difference if you do them alone or with 7 billion other people. Both actions are the same tiny marginal impact.
The alternative just comes off as an excuse to do nothing. As if car manufactureres will just keep building cars that nobody buys.
Climate change is a global problem, nothing besides global regulation that's actually enforced will have a meaningful impact. It's just too profitable to ignore climate impact for this to change.
What you're doing is just lying to yourself if you honestly think your actions (even if aggregated to hundreds of thousands of people doing the same), will be a meaningful contribution on the issue.
And just to be clear, pollution is another story entirely. That's primarily a local issue and can be significantly improved (not solved!) through personal responsibility.
How is this any different? You are either part of the solution or part of the problem, and accountable for your actions.
My point is that the contribution to climate change is exactly proportional to your personal emissions devised by the the total.
You talk about policy Solutions, but how is that any different than personal action?
Wherever they're boomers or not.
