1 If the system does not exist is it really a good idea to try to dismantle the current system.
2https://www.investopedia.com/terms/c/communism.asp#:~:text=Communism%20is%20a%20political%20and,is%20nonexistent%20or%20severely%20curtailed. Its both a economic and political system most system are. Also do you really think you can remove our economic system a quiet frankly laughable dumb idea without causing the political system to fall aswell. For example what if most people don't want to idiotically destroy one of the best systems ever created. Better send them to the gulags for not agreeing with the regimes plans ay.
3 Give me 1 example where this has not happened. It happens atleast 95% of the time so is this really a good idea. Even if we both agree that pollution is the fault of capitalism even though it comes mostly from the Ccp a communist country. Still explain to me why this is a better alternative destroying the lives for millions over earth. Which isnt even true if you want to actually study statistics sure there is increasing carbon dioxide. But this does not correlate to a linear increase it about caps out at 3 - 4 degrees increase. Which I dont know why you are so insistent that all this is the fault of capitalism when capitalist country's produce the least and fight it the most. You wont get rid of pollution of any kind by dismantling a great system.
4 I dont disagree I think toxic chemicals that harm environment should be banned that has nothing to do with economic or political systems. It simply does not there is no correlation.
5 The rise of technology can directly be connected to capitalism because massive technological leaps for example the first commercially wide spread cpu was created because of competition between 2 companies for capital.
6 Atleast come up with an idea because your like everyone in this jam you think capitalism is this big evil and someone else must have a better solution when that simply is not the case. Everyone can argue for what your arguing for and seem like someone who only cares about the environment and the poor . I do too and use to think the same until realizing and learning that this is a very unoriginal thought and has been tried hundreds if not thousands of times and only causes more suffering. If you truly care about the environment how about focus on helping it instead of destroying a system which is the only way it can recover. If you destroy capitalism today the world wont be fixed you will only destroy its defenders. There's this great quote dont know who it belongs to but it goes like this "The poor do not care about the environment" when you destroy this system it will only cause hard working people to become poor no one will care about the environment. How about creating rewards for company's for helping the environment. This is actually doable and as in game design instead of punishing the user rewarding them more for doing something right.
