In this model, it is hypothesized that there are a number of positive feedback loops that contribute to a downward spiral of population growth, resource depletion, and rising poverty see the land degradation section.

To take specific instances, water pollution has led to declining fisheries in rivers, ponds and canals in both urban and rural areas.
As the field of population-environment studies has matured, researchers increasingly have wanted to understand the nuances of the relationship.
Similarly, an American has an ecological footprint almost 9 times larger than an Indian—so while the population of India far exceeds that of the United States, in terms of environmental damage, it is the American consumption of resources that is causing the higher level of damage to the planet.
Developing countries tend to have higher birth rates due to poverty and lower access to family planning and education, while developed countries have lower birth rates.

Funding and research should be a high priority in these areas, but we must accept that technology can only do so much, and is only part of the solution. Consumption trends are somewhat more difficult to predict because they depend more heavily than population projections on global economic conditions, efforts to pursue sustainable development, and potential feedbacks from the environmental systems upon which the global economy depends for resources and sinks.
