We all know this. We are all powerless to change it. Corporations and governments control whether or not it can be changed. Politicians worldwide are being fed by the pollution industry. The poors voting changes nothing until the corporations and politicians decide to do something about it.
Walkable cities? Great idea. Needs politicians to approve zoning restrictions. Don’t drive cars? Great idea. Needs politicians to build public transportation infrastructure. Electric cars? Great idea. Needs corporations to produce them at an affordable cost. Etc etc etc.
There will never be a day when 10 billion people in the world get on the same page to demand the end of anything. We can’t even get a tenth of that many to agree to stop killing each other over border squabbles.
Bernie Sanders was the best-positioned potential third party candidate in probably the last 50-100 years. Why, then, didn’t Bernie run as a third party candidate? Because it’s not a viable strategy in the FPTP way we run elections here. He knew that it would be the worst option.
There isn’t a viable “other way”.
