some population experts say Earth cannot sustain a population of more than 10 billion people

due to limited resources such as land, water, and food. This is because as the population grows, so does the demand for these resources, leading to potential depletion and environmental degradation. In order to ensure sustainable growth, experts suggest implementing policies that promote conservation, efficient resource use, and equitable distribution of resources. Additionally, investing in technology and innovation that can increase the carrying capacity of the planet could also help support a larger population in the future.
