I been hearing about rising sea levels for decades and climate change, I remember when they called it global warming,"Scientists" have been panic peddling since the 1930s about climate stuff, and every time they were wrong. I feel that there is tons of money is climate hysteria, so just like the oil thing, they said we would deplete our oil reserves back in the 70s and they were wrong about that. So the climate stuff , i take with a grain of salt.
Nothing we do is going to change the behavior of other nations, but what we do sometimes has a ripple effect across the world, people see we are keeping the air and water clean with our oil, so they buy ours , leading other countries to do the same.
everything you said about musk is opinion and my only response with that is you have a right to yours, but I disagree. However i know that scientific development comes from war, and the wealthy funding people to find and breakthrough new frontiers. People living in the ghetto are not working diligently on world changing ideas.
