mollyfamwatEnvironment “The human population is now at 7.3 billion. There are now more than enough resources for everyone – but if nobody wants them, they won’t be there for us. As a result, we’re facing a crisis.
The world population is expected to reach 9 billion people by 2050. It’s a staggering number in the history of mankind. The United Nations estimates that 1.8 billion people are currently lacking a sustainable lifestyle, which can put them at risk of malnutrition , poor health , and disease, and can lead to population-wide problems such as unemployment , poverty, and natural resource depletion .
In his book “The Population Bomb”, Paul Ehrlich claimed that humanity would be facing a food crisis in the 1970s. In this current era of extreme malnutrition, one would think that Ehrlich’s dire predictions of a world that would be dangerously overpopulated by the 1980s would be met. However, in many ways the world has become even more overpopulated in the past 40 years. In the last century, there has been a global increase of 2.3 billion people. This is the equivalent of adding the entire population of Russia, but without the space to grow food.

Overcrowding: Serious problem
An overpopulation problem occurs when the population of a species exceeds its ecological nesting capacity. Overpopulation is a function of the number of people in relation to the important resources, such as water and essential nutrients, they need to live. This may be due to increased fertility, decreased mortality, increased immigration, or unexplained depletion of biomes and resources.

In nature, the crisis of species overpopulation is often solved by increasing predator populations. Predators tend to look for signs of weakness in their prey, and for that reason they eat older or unhealthy animals first. This method also has the drawback of managing prey populations and ensuring that they evolve to support inherited traits that allow them to escape predators.
How to reduce overpopulation?
In the absence of predators, species are limited by the resources they can find in the environment, but this does not automatically control overpopulation, at least in the short term. An abundance of resources can lead to a population explosion that results in more people than the environment can support. Under these conditions, hunger, thirst and sometimes aggressive competition for scarce resources can dramatically reduce populations in a very short time.
Some species seem to have a self-control that causes individuals to stop mating when they are in a confined space. This chosen abstinence can be caused by stress or pheromones.

In an ideal situation, when an animal population increases, the number of predators that feed on that particular animal also increases. Animals with congenital defects or weak genes are unable to compete for food with stronger, healthier animals.
In fact, a non-native animal may have advantages over native animals, for example. B. That it is not suitable for predators. If left unchecked, such animals can quickly become overpopulated and eventually wreak havoc on the environment.
The problem of human overpopulation
The population has grown steadily since the end of the Black Death in the 1400s, although the greatest growth has occurred in the last 50 years, largely due to medical advances and increased agricultural productivity. Population growth has slowed since the 1980s. The United Nations Population Division estimates (in 2011) that world population growth will virtually stop by 2050 and stabilize at about 9.15 billion people. According to the most recent estimates, the earth can accommodate between 4 and 16 billion people under current conditions. In 2013, the human population was estimated at 7 billion people. The world’s population is expected to increase by another billion people by 2025. Depending on the estimate of overpopulation used, there may or may not be human overpopulation.
The 1994 InterAcademy Statement on Population Growth notes that many environmental problems, such as the increase in carbon dioxide in the atmosphere, global warming, and toxic waste, have been caused by population growth. Other ills associated with overpopulation include increased demand for resources such as clean water and food, hunger and malnutrition, the use of natural resources such as fossil fuels faster than their renewal rate, and the deterioration of living conditions. However, some believe that abuse and overconsumption, especially by rich countries, are more damaging to the environment than overpopulation.
We need to act quickly to solve this problem and this can be done by making people aware of the disadvantages of overpopulation, otherwise we will face a huge crisis in the coming years.The overpopulation problem in our world is one of the most important problems which are facing mankind today. By overpopulation problem, it is meant the problem of a population which is higher than the sustainable capacity of the environment for supporting the lives of the people. Human beings are the most dangerous and largest predators on the planet but it is a fact that there will be too many of them. People will become the most dangerous predators on the planet unless scientists and leaders take measures to control the overpopulation..
