Earth's Population Has Surpassed The Planet's Capacity, Study Suggests

Earth's population is roughly 8.3 billion.

The study models ecological growth to track changes in population size and growth rates.

The analysis uses more than two centuries of population data.

The study distinguishes between maximum carrying capacity and optimum carrying capacity.

The study was led by Corey Bradshaw of Flinders University; carrying capacity is defined as the long-term number of individuals sustainable based on resource availability and regeneration rate.
