I don`t know if this is the right section to post this one here, so I`d like to know what could be the psychological effects if in the far future air pollution and global dimming become so severe that sky color and sun brightness changed. For exemple if these two artifitial phenomena changed sky color from light blue to reddish or grey for exemple and sunlight becomes dimmer and more ''transluscent'' and less bright. Would depression cases soar if such thing happen? How could people cope with such ugly and unhealthy thing?
This is Los Angeles sky in the recent movie Blade runner 2049. It looks much better than in the 1982 version but Earth look like lifeless .mars:
Notice the orangish sky and the scene don`t have any plant at all. It looks like Mars and I wonder how the man is breathing there. Whatever, this is an intellectual property and the creator has the right to create it as they want.
