Depleting Natural Resources
The consequences of overpopulation are very severe. The first is the loss of capital. Only a small amount of water and food can be generated on Earth, which falls short of current needs. Much of the environmental degradation seen in the last fifty-odd years is attributed to the rising number of humans on the planet. They involve chopping down trees, carelessly hunting animals, causing waste, and creating a host of other problems. Many involved in debates about overpopulation have found that acts of violence and aggression outside the war zone have risen exponentially when vying for resources.
Degrading the climate
With the overuse of coal, oil, and natural gas, some significant environmental impacts have begun to arise. Moreover,, the rapid increase in the number of vehicles and industries has had a significant effect on air quality. The increase in the amount of CO2 emissions contributes to global warming. Melting polar ice caps, shifting climate patterns, rising sea levels are some of the effects that we will have to face as a result of environmental pollution.
Conflicts and Wars
Overpopulation in developing nations puts a huge strain on the resources it should be helping to develop for growth. Clashes over water have become a source of conflict between countries, which could lead to wars. It allows more diseases to spread and makes them more difficult to manage. Starvation is a major problem facing the world, and the infant mortality rate is fueled by it. Poverty is the greatest hallmark we see when we talk of overpopulation. All this would only escalate if we do not pursue solutions to the factors impacting our population. We can no longer avoid this but there are ways to regulate it.
Increase in unemployment
When a nation is overcrowded, unemployment is generated because there are fewer jobs to help a large population of persons. The increase in unemployment is leading to crime, such as robbery because people want to feed their families and provide them with basic facilities of life.
The High Living Expense
As the gap between demand and supply continues to widen due to overpopulation, the prices of various essential commodities, including food, shelter, and healthcare, are increasing. This ensures that people need to pay more to live and feed their families.
Pandemics as well as the Epidemic
Poverty is associated with Thoth many environmental and social factors, involving overcrowded and non-hygienic living conditions, malnutrition, and inaccessible, inadequate, or non-existent health services for which the poor are more likely to be exposed to infectious diseases. Furthermore, high population densities raise the risk of new pandemics and epidemics.
Malnutrition, starvation, and famine
When resources are scarce, starvation, malnutrition, ill health, and diet-related diseases, such as rakes, become more likely. Famine is usually associated with less developed countries, and there is a high correlation with poverty levels.
Water shortage
Approximately 1% of the world's water is fresh and available. Overpopulation is a major problem that puts enormous strain on the availability of freshwater planet. According to the report, human demand for freshwater will be about 70% of the freshwater available on the earth by 2025. People living in vulnerable areas that already have limited access to such water would also be at great risk.
Lower Expectancy of Life
A significant proportion of the world's population growth is happening in less developed countries. As a result, the lower life expectancy triggered by population booms is faced by the less developed nations. This triggers a lack of services in these countries, resulting in less access to medical care, freshwater food, and employment, and, eventually, a drastic decrease in life expectancy.
Extinction
The effect of overpopulation on the wildlife of the world is significant. As demand for land increases, the loss of natural ecosystems such as forests, is becoming normal. Data have also been collected to demonstrate a clear correlation between the rise in the human population and the decline in the number of species on the planet. Some scientists warn that if current trends continue, as many as 50 percent of the world's wildlife species will be at risk of extinction.
Increased intensive agriculture
With population increase over the years, farming methods have developed to produce enough food to feed a greater number of people. However, these intensive farming practices cause harm to local habitats and land that could pose problems in the future. Intensive farming also contributes to climate change due to the machinery required. If the population continues to expand at its current pace, this trend is likely to increase.
Faster Climate Change
Overpopulation forces larger nations, like China and India, to continue to develop their industrial capacities. They are now ranked as two of the three biggest contributors to pollution in the world, other than the United States. According to 97% of the scientific establishment, human emissions are changing global temperatures. If more is not done to reduce individual carbon footprints on a large scale, larger populations will accelerate these changes. Environmental Factors that Contribute to Population Growth
Temperature
Climate change involves changes in mean temperature and precipitation as well as increases in extreme weather her events; thus, determining how species will respond to climate change requires understanding how organisms respond to change in both mean and extreme conditions. In this case, countries' population's climate like the Philippines has a huge then given the fact that only has a small demographic. When people experience a sudden rise in temperature people might do things to overcome it and it may cause an increase in our population.
Resources
In the past years, resources have been too much for everyone because the population is manageable and can sustain. However, in our era today, if the population will keep on increasing it will be surely hard for us to have enough resources and to sustain human life. As the population goes up, demand will also increase and the supply will do whatever they can do to sustain the needs of the people.
Population Density May Fluctuate
Any population has a built-in, characteristic growth rate. This is the rate at which the group would grow if food and space were unlimited and individuals bred freely. Environmental factors do affect a population’s growth rate, however. The interaction of the population’s rate and the environment determines the density of the surviving population. The maximum number of individuals that a given environment can support is called the carrying capacity.
