Overpopulation is where the number of existing human population exceeds the carrying capacity of Earth Overpopulation is caused by three factors decline in death rate, medical advancements, and immigration. The decline in death rate this factor leads to the lack of the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize.Overpopulation shows that there are many factors that can increase the death rate for short periods of time the ones that increase the birth rate do so over a long period of time. Another factor leading to overpopulation medical advancement in supplies helps keep our injured and diseased healthy by having the materials in the medical field to keep them well and alive and sustaining keeping the body efficient. Medical science made many discoveries thanks to which they were able to defeat a whole range of diseases. Illnesses that had claimed thousands of lives till now were cured because of the invention of vaccines. Science also helped by giving us in providing ourselves better food and a increase on food supply which allowed families to feed more mouths by being able to get more food which keeps us alive and healthy that could lead to overpopulation. The last factor is immigration is a reason in overpopulation because the people who immigrate are looking to find jobs , a home , and money cause the country they lived in might not had as good resources,or jobs , or lack of money payment. So they move to a place like United States to get a better opportunity to work at better jobs and payment in terms of medical, education, security and employment.The end result is that those people settle over there and those places become overcrowded.Difference between the number of people who are leaving the and the people who are entering leads to more demand for food, clothes, energy and homes. This gives rise to shortage of resources. Though the overall population remains the same, it just affects the density of population making that place simply overcrowded. The effects of overpopulation is the depletion of resources which is bad for a community which lead to us to lose our food, and medical, and technology supplies to sustain our life it means we would have a shortage on things. The other effect is the environment can be effected by more people more cars being drove and it will overuse of coal, oil and natural gas, it has started producing some serious effects on our environment vehicles and industries have bad air quantity the consequence we face environment pollution if overpopulation gets out of hand.
The problem is growing out of control
