Have you traveled to third world countries with very high population densities? Have you breathed the air on their streets? Travel to China, India, parts of the Middle East, other parts of Asia, and realize just how foul the air there is to breathe. That's what you want for the US? The evidence is already strong that plastics, PFAS, and CO2 are not recycled; they just keep piling on in the environment and in the human body. You can literally smell plastic burning in the air in those countries and regions, and the immune system reacts very strongly to it in a negative way. Developing anything cool will be the last thing on the mind at that time.
