Yes, let’s pack people in a dense area where diseases and tempers can and will run rampant because THAT has never happened before.
Sorry, I refuse to live on top of other people. Housing is not the enemy of nature - housing that is not in tune with nature is. It is completely possible to build homes that blend in with nature without having to resort to ultra-dense, 5-story brick behemoths filled with people who loathe one another.
I see what you are trying to convey, and I agree with you to an extent, but density is not the answer to sustainable housing.
I reply to your infographic with a scientific paper that shows higher densities lead to higher CO2 emissions: https://www.mdpi.com/2073-4433/12/9/1193#:~:text=Regarding CO2 emissions%2C the,density%2C the higher the emissions.
This study was done in Spain.
Another study, in Nature, also shows that lower density is better for reducing carbon emissions and climate change. https://www.nature.com/articles/s42949-021-00034-w
Sorry, but you and your infographic/sources are not supported by science.
