Population Growth, Industrialization, and the Environment
Human population growth was relatively slow for most of human history. Within the past 500 years, however, the advances made in the industrial, transportation, economic, medical, and agricultural revolutions have helped foster an exponential, "J-shaped" rise in human population (Southwick, Figure 15.1, p. 160). The statistics associated with this type of growth are particularly striking: "Human beings took more than 3 million years to reach a population of 1 billion people...The second billion came in only 130 years, the third billion in 30 years, the fourth billion in 15 years, the fifth billion in 12 years..." (Southwick, p. 159). As human population has grown, there has been simultaneous growth within the industrial sector. Both of these increases have greatly contributed to environmental problems, such as natural resource depletion, ecosystem destruction, and global climate change. Also linked with the increasing human population are many social problems, such as poverty and disease. These issues need to be addressed by policy makers in the near future in order to ensure the survival and sustainability of human life.
One of the major effects of the huge population increase has been the depletion of natural resources and the destruction of ecosystems. In the 1960's, theorist Paul Ehrlich predicted that, given the skyrocketing figures of human population, the amount of food produced would not grow at a fast enough rate for human survival (Professor Carr Everbach, personal communication). He predicted mass starvation and death by the year 2000 as the result of uncontrolled population growth. Clearly, this did not occur. Ehrlich did not foresee the advancements ma...

Section 8 of the Safety, Health and Welfare at Work Act (2005) puts the onus on the employer to ensure systems of work that are planned, organised, performed, maintained and revised as appropriate so as to be, so far as is reasonably practicable, safe and without risk to health. Section 19 of the Act requires the employer to conduct a risk assessment of work activities and Schedule 3 of the Act provides the general principles of prevention to ensure the safety of employees in the workplace.
The worldwide population is approaching 7 billion and is expected to reach 9 billion by 2050 (Baird). This projected population number is down from a once predicted 16 billion (Baird) and while some are not concerned, others are worried about any increase in population. Population growth is discussed in the articles “Too Many People?” by Vanessa Baird; “Population Control: How Can There Possibly Be Too Many of Us?” by Frank Furedi; and “The Population Bomb Revisited,” by Paul R. Ehrlich and Anne H. Ehrlich. Baird and Furedi concur that a concern for population growth has been around since mathematician Thomas Malthus, in 1798, warned that overpopulation could lead to “the collapse of society” (Furedi). Furedi claims that too much human life is being used as an excuse, by population control supporters, for the world’s current and future problems. Baird tries to discover if “the current panic over population growth is reasonable.” For Ehrlich and Ehrlich the concern over population growth is very real, and they reinforce and support their book “calling attention to the demographic element in the human predicament” (Ehrlich and Ehrlich 63). While taking different approaches to their articles, the authors offer their perspectives on population growth, population control and the environmental impacts of a growing population.

In today’s society that we live in, there are countless of environmental problems that we face, such as global warming, fishing, pollution, and many other topics of that matter. These issues have affected our environment for the worse and have caused problems physically and economically. Yet, out of all the issues that effects our world on a daily basis, it is shown that overpopulation is one if not, is our biggest issue in our environment that is only getting worse due time, especially due to the rapid growth of the human population and the limited resources that are left on earth that we absolutely need to tend to our growing population. Even Dr. Charles A. Hall, who is a systems ecologist, states that, “Overpopulation is the only problem, If we had 100 million people on Earth or better yet 10 million, no others would be a problem.” Which helps prove that overpopulation is a major issue that we must act upon if we want to save our world.

Most people believe that the population of the world today is growing at an exponential rate. Environmentalists, politicians, and the concerned public are trying to prove that we are depleting our resources and are slowly killing ourselves. Others argue that technology and new inventions will fix and solve our population problems, and that the population growth is actually slowing down. .

The question of overpopulation's impact on the environment is multi-dimensional and far beyond the scope of a single essay. The issue has to do with considering the environment a normal good while at the same time understanding the impact of industrialization on increased pollution levels. Relationships between industrialization, overpopulation, global pollution, regional pollution, resource depletion, and numerous other environmental and social concerns form a multi-dimensional series of feedback loops, all of which feed back on the original system. Computer models developed by economic research institutions to predict environmental and developmental impacts of population growth (ex. The World Bank, The Economic Research Service) are n-dimensional, only to be accurately evaluated using advanced statistical regressions and matrix analysis. As such, this paper will assume that there is a direct correlation between population and natural resource depletion (environmental degradation by way of pollutants is an entirely different, and more complicated issue), and the most cost-effective way of amelioration would be to restrain population growth. Given that, what is the correct means for policy to approach the population problem? The options include contraceptive distribution, family planning, general economic development, and gender equality among others. Essentially, policy has to address whether population can be restrained with a "tech fix" such as contraceptives or only after a broad socioeconomic shift.
The reduction of the Earth's resources has been closely linked to the rise in human population. For many thousands of years people lived in relative harmony with their surroundings. Population sizes were small, and life-supporting tools were simple. Most of the energy needed for work was provided by the worker and animals. Since about 1650, however, the human population has increased dramatically. The problems of overcrowding multiply as an ever-increasing number of people are added to the world's population each year.
Jacques-Yves Cousteau once said, “Overconsumption and overpopulation underlie every environmental problem we face today” (“Population,” Internet). With the current statistics, Jacques could not be more accurate. Every second, 4.2 people are born and 1.8 people die, which would be a net gain of 2.4 people per second (“Population,” Internet). At this steady rate, the environmental health is spiraling downwards, and it is safe to assume humans are responsible for this. As the population increases, harmful effects on the land, water, and air also do.
Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.
One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will almost double in size. This means that we will need more food to support us. A study in 1986 by Peter Vitonesk, a Stanford biologist, showed that the humans are already consuming about 38.8 of what is possible for us to eat. Thus, if the population keeps increasing, the percentage will increase also, making us closer and closer to the biophysical limits. By studying the earth's capacity, Dr. Cornell, another biologist, believes that we are already crowded for this would. He believes that our world can only support two million people. Not only this, but population can cause complicated problems to the countries with very high population. These countries will need more schools to educate its people, they will need more hospitals and public health to take care of their people, and they will need more water and more soil for farming to feed all the people. In order to solve the population growth problem, the people should be educated. Once the people are educated they will be aware of the problems they ca...
This problem of population growth leads to a number of solutions that could have significant implications on the quality of life. Taking no action and allowing population to grow unchecked could possibly risk the entire human species if food or clean water were to become unavailable worldwide. Aiming for zero population growth would in theory maintain the existing quality of life since a stable population would not increase their use of resources. However not all resources are renewable, so scarcities could still occur with a fixed population size. In an extreme case permanent resource depletion under zero population growth could have the same extinction effect that unchecked growth can lead to. Despite the escalating risk of unchecked population growth, technological advances necessitated by the increase in population will at least maintain the quality of life and could possibly improve conditions.
