How much humanity can the earth take?

The world population is growing rapidly. In 2020, there will be around 7.8 billion people on earth, and the trend is rising. However, more and more people also mean a greater demand for living space and raw materials. Negative effects on ecosystems and biodiversity have long been noticeable.

How many people can the earth handle? Maximum numbers of between 300 million and 3 billion people are being thrown into the room. But how can the world population be measured quantitatively and qualitatively? Must humanity shrink for species to survive?
