How many people can the earth take?

  • Our biosphere between evolution and overpopulation
  • Geist Heidelberg, In dialogue

The world population is growing rapidly. For 2020, a bio number of 7.8 billion people is stated, and the trend is rising. But more and more people also mean a greater need for living space and raw materials. Negative effects on ecosystems and biodiversity have already been noted.
How many people can the earth take? Maximum numbers between 300 million or 3 billion people are thrown into space. But how can the world population be measured quantitatively and qualitatively? Must humanity shrink for species to survive?
