Also asked, what is the maximum population the Earth can sustain?
Earth's capacity Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
Likewise, what will happen when the human population exceeds the Earth's carrying capacity? If these factors improve, the carrying capacity increases. If the factors become less plentiful, the carrying capacity drops. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
how many people are in the World 2019?
7.7 billion people
How Much Longer Can Earth Support humans?
Earth could continue to host life for at least another 1.75 billion years, as long as nuclear holocaust, an errant asteroid or some other disaster doesn't intervene, a new study calculates. But even without such dramatic doomsday scenarios, astronomical forces will eventually render the planet uninhabitable.
