Population Essay (500 words)
Introduction:
Population commonly refers to the total number of people living in a particular region. However, the word population does not only mean the human population but also the wildlife population and the overall population of animals and other living organisms who have the ability to reproduce. Ironically while the human population is increasing at a rapid pace, the population of animals is going down.
- How Science and Technology has Led to Human Population Explosion?
There are several factors that have led to population explosion in various parts of the world over the last few decades. One of the leading factors is the progress in the field of science and technology. While earlier there was a balance between the birth rate and the death rate of human beings, the advancement in medical science has created an imbalance in the same. Medicines and advanced medical equipments have been developed to cure several diseases. With the help of these, the death rate among human beings has been brought down and this has led to population explosion.
Besides, technological growth has given way to industrialization. While earlier most people were involved in agricultural activities and earned their livelihood via the same, many have now turned towards jobs in different factories. The population of the regions where these industries are set up is thus becoming denser by the day
Impact of Human Population Growth on Wildlife Population
While the human population is on the verge of explosion, the wildlife population is decreasing over the time. The population of several species of birds and animals has gone down drastically owing to factors for which the human beings alone can be held responsible. Some of these are discussed below in detail:
- Deforestation
The wildlife animals reside in forests. Deforestation means destroying their habitat. Nevertheless, the human beings are ruthlessly cutting and destroying the forests to fulfil their own needs. Several species of animals have decreased and several others have gone extinct due to the degradation or loss of their habitat.
- Growing Pollution
The growing air, water and land pollution is another major reason why several animals are dying at an early age. Many species of animals are not being able to cope up with the growing pollution. They incur certain diseases due to it and face fatal consequences.
- Changes in the Climate
The climate in various parts of the world has changed drastically. Many areas that earlier received moderate rainfall now witness flood like conditions. Similarly, the areas that remained mildly hot during the summer season now experience extremely hot weather. While the human beings are equipped to adapt to such situations, animals cannot withstand the same.
.Conclusion
Man has always thought about his well-being and comfort overlooking the impact it has on the plants, animals and the overall environment around him. If human beings continue to behave this way earth would no longer remain fit for the survival of the human beings. It is time we must recognise the importance of controlling the human population as well as the practices that are ruining our planet.

Hi,
my mighty gorgeous ,

The Problems of Over Population There are several problems that affect the world today: war, crime, pollution, and several others. Overpopulation is a serious dilemma that is growing every year, every minute, and every second. It is the root of most, if not all, of the world’s problems1. It is the greatest global crisis facing humanity in the twenty-first century. Overpopulation is the major global problem because of several reasons. Most of the problems we have today, such as ocean depletion, food shortages, water shortages, air pollution, water pollution, and global warming are the effects of overpopulation2. The more people there are, the more resources consumed and the more waste created. A child born today in the United States for…show more content…
Mankind is increasing the greenhouse gas levels by burning fossil fuels and deforesting the earth7. As the population increases, atmospheric concentrations of greenhouse gases rise rapidly which affect the ability of the outgoing energy to pass through the atmosphere, [which] effectively heats the Earth8. Another predicament is the acid rain created by air pollution, which in turn, is created by the increasing population. Acid rain’s spread and damage involves weather, soil, and the life cycles of plants and animals on the land9. Air pollution is created from the burning of fossil fuels in cars, trucks, planes, and homes. The smoke and fumes rise into the atmosphere and combine with the moisture in the air to form acid rain10. As it rains, it eats away on things they settle on and contaminates lakes, drinkable water, which affect plants and animals11. Overpopulation also causes conflict. If many people live very closely together, there is a greater chance of conflict, which results in higher crime and even sometimes war12. This is why overpopulation is the major global problem. There are several things that cause this problem to come about. A major cause is the rise of living standards as the world approaches the twenty-first century, which resulted from the industrial revolution.
