The political spectrum will change.Good video - Kurzgesagt is one on my favourite YT channels. Very fair and balanced.
As an aside, I absolutely hate it when people speak of overpopulation in the the second-largest continent on the planet. The average African uses far less resources than any other demographic on Earth.
Furthermore, Europeans have no right to talk of overpopulation considering how their numbers spilled across four continents and as a group have polluted more than any other group in human history
India and China each both outnumber Africa in it's entirety, but they're major economic powers and nuclear weapon states, so they are beyond reproach in the white man's world
