There are many problems that effect that world today. I believe that over population is one, if not the biggest problem of the twenty-first century. Many people do not know that every second of the day an average of 4.3 babies are born in the world. (Population Reference Bureau [P.R.B.], 2001.) â€œ The 20th century began with a world populate by 1.6 billion people and will end with 6 billion inhabitants-with most of the growth occurring in poor countries, demographers estimate.â€ (Feinsilber, 1998. P. 1) Today entering the twenty-first century the population is about six billion. (P.R.B., 2001) Also, every year the worldâ€™s population will grow over seventy-eight million. (Sullivan, 1999. P.3) Meaning the world may very well already be over populated. We as the people living on this earth need to do something about it for the future generations.
The human population is growing rapidly for various reasons. The rise in living standards plays a big role in the increase since the industrial revolution. The industrial revolution provided a lot more jobs that were available for the people in the community. The pay has even increased which allows people to have more children because they have
the money to support a larger family. Medicines, better doctors, better housing, and a better way of life than before all increase the life expectancy of humans on this earth. Everyday newer medicines and vaccines are created to help people fight disease and sicknesses that used to kill off humans in the past years. Mothers and their newborns because of highly educated doctors, have a much better chance of survival during birth. Which in earlier times would often be rare. (For both mother and child to survive) Even a lot of religions today in the world discourage the use of birth control. Keeping the control of how many children a family has up to â€œGodâ€ or whomever is being worshiped. Also in this world, the husband of the family feels the need to continue the family name. In order for this to happen the family must have a boy. While these families try for a boy they can never be certain, instead they might have four or more girls before the mother gives birth to a baby boy. Immigration, which is the movement of people into a country, plays another role in the growth of the population. As people move into other countries with more jobs and better medicinal services the desire to have children rises. Knowing that their childrenâ€™s future will benefit from the specific country they immigrated too. (Cunningham-Saigo, 2001. P. 151-152)
Overpopulation is a main cause for many of todayâ€™s environmental problems for several reasons. Some of the problems that overpopulation contributes to are ocean depletion, food shortages, water shortages, air pollution, water pollution, and also global warming. The more people that are on this earth causes more resources to be used which results in more waste created. A child born today in the United States for instance will
produce fifty-two tons of garbage and consume eleven million gallons of water by the age of seventy-five. (â€œWorld Overpopulation Awarenessâ€, 1998) Thatâ€™s only taking into consideration garbage and water! One can just imagine how much more resources will be used up by just one human being, within an average life span. Many natural resources that we are using today, if continued to be used as quickly, will deplete from the earth and will never return. Many resources are vital for survival. By using them up quickly we are not benefiting ourselves, but we are ruining our future. Conserving the resources would benefit our futures greatly. The truth is we should only be using the worlds natural resources as fast as they can replenish themselves. Today that does not seem to be happening. Another problem that is caused by overpopulation is the changing of the climate. Burning fossil fuels and deforesting the earth increases the greenhouse gas levels. This eventually heats the earth, which could have various dangerous effects like the depletion of the ozone layer. (â€œWorld Overpopulation Awarenessâ€, 1998) â€œ1998 was the hottest year ever recorded since keeping record began in 1886, and the 14 hottest years have occurred since 1980.â€ (Sullivan, 1999.P.4) Another major effect of overpopulation is acid rain, which is caused by air pollution. Air pollution is caused by the burning of fossil fuels in things such as cars, trucks, and planes. When the fumes from these types of transportation rises into the atmosphere and combine with moisture in the air it causes acid rain. As the acid rain falls it eats away things the rain settles on. Damages range from things such as weather, soil, and the cycles of many plants and animals. Acid rain also contaminates lakes and even drinkable water. (â€œAcid Rain Programâ€, 2000. P. 1-2) Many of the effects of acid rain directly effect us. If acid rain
were to contaminate our drinking water, then where would we stand? Water is the main substance of our bodies and without we can not survive. Overpopulation has also increased industrial development, which then contributes to higher living standards. The increase in industry shrinks the amount of available freshwater because of the constant dumping of industrial waste. Also the rise in living standards causes people to consume more which in return produces more waste and also raises life expectancy. This couldnâ€™t possibly help the issue of overpopulation. When too many people are living on this planet, who are not properly informed about the waste that they are producing, how could the effect be lessened? The outcomes could be very hazardous to the earth itself.
I believe that there are many ways to go about controlling population in the world. The first thing that must be done in my opinion would be to educate. A lot of people do not realize the damage that they are causing to the earth for future generations. I believe that if they knew they might decide to help. Educating people could be through seminars, conferences, or even just explaining it to a friend. Any kind of communication with some one about the problem and effects of overpopulation could lessen the possible outcome. Informing people to cut down on natural resources like car-pooling to save energy, recycling paper to lessen the amount of deforestation, or even making sure you shut the water of in between stages of brushing your teeth. Every little thing to help conserve counts. I think that people; boys and girls should be educated more about pregnancy and the effects of having the child. People knowing the consequences of having a child would be more apt to use birth control or even refrain from sex altogether. I also believe those teenagers or whomever, who decide to become sexually active should have a better
understanding of birth control. Making birth control widely available could in many ways lessen the birth rate. One major population control option would be to put laws on how many children a person is allowed to have. Although passing a law like that would cause much controversy. The issue of over population has to be dealt with in some way and I feel the government should make a decision before it is too late, whether they put laws on natural resource use or births per family something needs to be done.
