Population explosion – Cause and Effect

|| Post On > Apr 1 2022 ||

Our total environmental condition deteriorates in everyday life but we yet not concerned ourselves for save us from different types of natural calamities and extinction of several types of animals spaces groups, it is true that only humans are responsible for polluting the environment, but if we have a little bit concern than it will make us positive thinker to save our environment. 

The first and foremost emerging problem in the world is the population explosion that directly impacts our environment and every vital element of our environments such as water. trees, air, and many other things. 

Each human being has a legitimate claim on a sufficient and fair amount of Earth’s resources. But with a population approaching 8 billion, even if everyone adopted a relatively low material standard of living like the one currently found in Papua New Guinea, it would still push Earth to its ecological breaking point. Unfortunately, the “average person” on Earth consumes at a rate over 50% above a sustainable level. Incredibly, the average person in the United States uses almost five times more than the sustainable yield of the planet.


 Today the Earth is home to more than 7.8 billion people. By 2100 the population is on track to hit 10.8 billion, according to the United Nations — and that’s assuming steady fertility declines in many countries. Interestingly, if extra progress is made in women’s reproductive self-determination, and fertility falls more than the United Nations assumes is likely, the population in 2100 might be a relatively smaller 7.3 billion. 

The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally, with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990, according to the World Health Organization (WHO). This is welcome public health news, of course. 

At the same time, lifespans are increasing around the world. Those of us who are alive today will likely live much longer than most of our ancestors. Global average life expectancy has more than doubled since 1900, thanks to advancements in medicine, technology, and general hygiene. Falling mortality rates are certainly nothing to complain about either, but widespread longevity does contribute to the mathematics of increasing population numbers. 


 An increase in population will inevitably create pressures leading to more deforestation, decreased biodiversity, and spikes in pollution and emissions, which will exacerbate climate change. Ultimately, unless we take action to help minimize further population growth heading into the remainder of this century, many scientists believe the additional stress on the planet will lead to ecological disruption and collapse so severe it threatens the viability of life on Earth as we know it. 

Each spike in the global population has a measurable impact on the planet’s health. According to estimates in a study by Wynes and Nicholas (2017), a family having one fewer child could reduce emissions by 58.6 tonnes of CO2 equivalent per year in developed countries. 

The scarcity brought about by environmental disruption and overpopulation has the potential to trigger an increase in violence and political unrest. We’re already seeing wars fought over water, land, and energy resources in the Middle East and other regions, and the turmoil is likely to increase as the global population grows even larger
