Tutorial

what's covered
This tutorial will cover the topic of population growth solutions. We will discuss overpopulation and how humans have exceeded our earth's carrying capacity with their current lifestyles. We will discuss the impacts of overpopulation, as well as efforts to address the challenges it poses.

Our discussion breaks down as follows:

  1. The Current State of Overpopulation
  2. Impacts of Overpopulation
  3. Addressing the Impacts of Overpopulation


1. The Current State of Overpopulation

Overpopulation essentially means that there are more humans than the earth can sustain. Humans have exceeded our earth's carrying capacity with our current lifestyles.

did you know
Over 83 million people per year, 200,000 per day, or 150 per minute, are joining the human species.

Human population growth has largely occurred as a result of improved medical care and technology. The more people living on the earth, the larger the human population, and the greater the strain on resources such as food, water, energy, and space.


2. Impacts of Overpopulation

Impacts of population growth are diverse.

Impacts Result
Food Food supplies may not always be able to match population expansion. Current population size has resulted in a degradation of arable land in order to provide food and other services, making the providing of food even more difficult.
Water Population growth increases the demand for water, but many polluting human activities make it difficult to keep water supplies safe for drinking and bathing. Primarily in developing countries, the challenge of adequate and safe water supply has resulted in the deaths of millions every year. On top of that, oceans and their coastlines have been polluted, and fisheries over-exploited, decimating aquatic ecosystems and species.
Land Primarily due to overpopulation, half of the world's forest cover, or 10 million hectares per year, has been razed, cut, burned, and bulldozed to the ground. As natural resources are mined or cut from local ecology to produce infrastructure for humans' increasing population, approximately 66% — or 2/3 of the world's biological species — are declining in population. Not only does this impact biodiversity and habitat availability, but it also reduces carbon sinks like forests, which can absorb carbon dioxide and slow global climate change.
Air Climate change worsens as air pollution increases, primarily from overpopulation demanding more burning of fossil fuels. As the earth's heating and cooling systems intensify, it may lead to rising sea levels, more frequent and intense natural disasters, flooding, and droughts. Population growth's increase in air pollution is also causing more airborne heavy metals, which when breathed in, cause health problems and even death.


3. Addressing the Impacts of Overpopulation

In response to such severe impacts and the speed of population growth, people are building facilities and infrastructure to support how fast populations have grown in such a short time period.

Apartments Under Construction

Private companies and policymakers are attempting to develop sustainable strategies, plans, and technologies to respond to increasing population demands.

Some countries are discussing, or even enforcing, child limitation laws to enforce population stabilization or even decline.

Scientists and engineers are developing models, through analysis of current effects, to better understand potential futures and to develop technology to mitigate or eliminate challenges posed by population growth.


summary
Today we learned about overpopulation, which means that there are more humans than the earth can sustain. We learned about the impacts of overpopulation, such as climate change and a decrease in biodiversity. We also learned about population growth solutions — efforts being made to mitigate or eliminate those impacts, especially in the future.
