What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? In a brief summary on the history of the modern environmental movement from the 1960s to the present, its focus was on a few prominent environmental issues and disasters. The environmental movement has evolved significantly in the last five decades. Today, many of the rallying points of the environmental movement have become ingrained into American society. Air and water quality standards are regulated for the public good, endangered and threatened species are protected, and chemicals and products go through a rigorous testing process to determine potential health and environmental threats. Today the environmental movement in America is divided into three levels: local, national, and international 2. Explain the primary concern over exponential population growth.

...Environmental Science and Human Population Worksheet 1. What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? The modern environment movement began on April 22, 1970 largely due to the release of the book The Silent Spring that is written by an environmentalist name Rachel Carson. Overtime, I think the environment has improved tremendously from where and how it all began. With the help of the National Resources Defense Council, many things started happening for the betterment of the environment. Many Acts and laws were passed such as the Environmental Protection Agency, the Clean Air Act and the Endangered Species Act. The National Resources Defense Council has created acts and laws that have help to stop the mistreatment of the environment as well as the senseless killings of some of our wildlife that are still effective to this very day. 2. Explain the primary concern over exponential population growth. What promotes exponential population growth? What constrains exponential population growth? The primary concern over exponential growth is, the more people there are and the more resources we use will eventually lead to the Earths downfall thus leaving us with a weak environment. The population on Earth has grown over the past few decades and with that, growth come the more frequent use of unnatural resources. There are more people using and trying to advance technology and while it seems like a...

...Human Population Demographic transition is defined as changes from high birth rates in a country to low birth rates being stable for the demographics. (Montgomery, K. n.d.). This is the changes in a country society because of the births and deaths in a country. In the texts its say’s that demographic transition is from high fertility and morality to low fertility to morality. (Editorial Board [EB], 2013, p. 191). Demographic transition is known for collecting data from countries about human population and is also known for the categories in 4 stages. (EB, 2013, pg. 192). Stage one deal with pre modern times in demographic transition. This stage change in the 18th century when the balance was broken in Western Europe. In stage one the birth rates and death rates are very high. This cause very slow population growth until the 18th century as stated above. The causes of deaths in stage on were fever, plagues, infections, TB, measles, whooping cough, and dysentery. Along with these problem poor hygiene, and clean during water wasn’t available. Some has called this stage the “Malthusian stalemate” because of its characteristics. (Montgomery, K. n.d.). Stage two; many have seen a rise in Europe population because the death rates have decreased slightly. It is still debatable that the birth rates stayed the same or risen slightly. The decline in death rates was seen in Europe starting in the 18th century in the north and the west. The reason for the lower death...

...SCI/256: Week 1 NOTES – Environmental Science and Environmentalism ------------------------------------------------------------------------------------------------------------ Environmental Science is the study how humans interact with their environment. Environmental Science is interdisciplinary - brings together information from several physical, biological and social sciences. The main goal of environmental science is to solve environmental problems using science. What is “Natural Environment”? –Environment is our natural surroundings consisting of living and nonliving things. The Earth is part of our environment, comprising 4 “Spheres” Biosphere (living things), Hydrosphere (water), Atmosphere (Air) and Lithosphere (land). Human Impacts: Humans are altering the environment and creating environmental problems. Our main problem involves human population growth and the use of earth’s resources and environmental pollution. Environmental Problems – Examples (a) Depletion of Natural Resources (b) Deforestation (c) Global climate changes (d) Loss of biodiversity (e) Pollution of Air, Water, Land Ecological Footprint is a measure of humanity’s demand on nature. A carbon footprint is "the total set of greenhouse gas (GHG) emissions caused by a person Impacts of Rapid Population Growth: Rapid population growth depletes the Earth’s resources diminishes, quality of life, and damages the environment. Impacts on the environment include, (a) land degradation, (b) air and water pollution...

...The definition of environmental science is the study of the environment and the quest for the solution to environmental problems such as pollution, global warming, and disappearing resources. The subfield of environmental science that is interesting is ecology. Ecology is the study of the interactions of organisms and some physical aspect of their environment. An example is the study of how two individual populations of two different organisms impact their environment through a symbiotic or competitive relationship. The relationship between science and technology affect global problems in today’s society. As the development of technology increases, the impact on the environment also increases. The advancement of science and technology help increase the material lives of humans. Medical technology progression has extended the length of the human life and lower infant and child mortality rates that have dramatically increased the world population. This increase in the population leads to a decrease in natural resources that were also depleted. To compensate for the increase population rates, more land has to be cleared to make room for the population and thus destroying the environment and depleting its available resources beyond repair. The movement of people, goods, money, and information has drastically increased since the late 1980s due to technological advancements. This globalization has changed the nature of our society. This globalization has also led to...

...ton1.1 Major Themes of Environmental Science The study of environmental problems and their solutions has never been more important. Modern society in 2009 is hooked on oil. Production has declined, while demand has grown, and the population of the world has been increasing by more than 70 million each year. The emerging energy crisis is producing an economic crisis, as the prices of everything produced from oil (fertilizer, food, and fuel) rise beyond what some people can afford to pay. Energy and economic problems come at a time of unprecedented environmental concerns, from the local to global level. At the beginning of the modern era—in A.D. 1—the number of people in the world was probably about 100 million, one-third of the present population of the United States. In 1960 the world contained 3 billion people. Our population has more than doubled in the last 40 years, to 6.8 billion people today. In the United States, population increase is often apparent when we travel. Urban traffic snarls, long lines to enter national parks, and difficulty getting tickets to popular attractions are all symptoms of a growing population. If recent human population growth rates continue, our numbers could reach 9.4 billion by 2050. The problem is that the Earth has not grown any larger, and the abundance of its resources has not increased—in many cases, quite the opposite. How, then, can Earth sustain all these people? And what is the maximum number of people that could live on Earth, not just...

...Principles of Environmental Science Jennia McCray Env/100 June 30, 2011 Professor Elshorafa Principles of Environmental Science Environmental Science is a multidisciplinary field that combines information from many different punitive areas of study, such as biology, geography, chemistry, geology, physics, economics, sociology (mostly demography or the study of populations), cultural anthropology, natural resources, management, agriculture, engineering, law, politics, and ethics. Environmental science and nature’s environmental problems we faces are generally complex and are not as simple as the meaning portrays. The goals of environmental scientists are to try to form basic principles about how the natural world operates. They then use these principles to develop applicable solutions, mostly derived from scientific knowledge, to address environmental problems. Using scientific evaluation is the key to successfully achieving a solution to any environmental problem. Before this, you must completely understand what science is opposed to what it is not. Science is not just a body of knowledge, as some see it to be, but much rather a collection of facts about the natural world. In addition, science is also a systematic way to investigate the natural world, what we refer to as the dynamic process. Science looks to decrease the conspicuous complexity of earth to general principles, those principles help to make predictions, solve problems and create new insights. These principles...

...Environmental Science Worksheet The publication of Rachel Carson’s book Silent Spring helped start the environmental movement. Her book discussed the harmful pesticide DDT to humans and animals. Many environmental events contributed to the environmental movement. For instance, before 1960 many people did not acknowledge environmental issues as an importance until humanity, air, water, and animal life were put in danger. The oil spill on the coast of California and Massachusetts was one major event and the people saw a greater need to address concerns of the environment. Environmentalist, scientists, and many other people conducted more research and depended on the development of advanced technology to educate the people and to save the Earth. In December of 1970, the United States Environmental Protection Agency originated to address and help the various environmental issues (EPA, 2011). Birth rate is the constraint for population growth. An increase (exponentially) in the population’s resources like food, water, and better crop conditions promotes exponential growth. “Exponential growth is positive feedback” (Botkin & Keller, 2009, Ch. 3.2) because contributing factors like high birth rate and good health conditions of the population have a J shape whereas the logistic growth curve is S shaped. The logistic growth curve has many determinants like disease, death, and unhealthy conditions in the environment. Also birth rate may not slow down or decrease just because the population...

...Environmental Fundamentals ENV 100 September 9, 2013 Environmental Fundamentals For a number of years, the planet and its environment have strived to meet the demands of the increasing growth in populations, global warming, and altered habitats, which has produced a global impact on the sense of balance between nature and man. The struggles amongst the environment do not affect one group of individuals or living entity; the whole planets population is concerned by environmental troubles. Each living entity on the planet may affect the environment. In order for individuals to preserve the planet, assistant in resolving environmental problems, and attain sustainability of the planet as it grows, a person should know the fundamental principles of environmental science. Environmental science may be described as the study of human connections with the environment. It is the interdisciplinary subject that blends knowledge from several disciplines such as geography, biology, chemistry, physics, geology, economics, cultural anthropology, sociology (particularly demography, the study of populations), natural resource management, engineering, agriculture, law, ethics, and politics (Berg & Hager, 2009, p1.4).

...Basic Issues in Environmental Science What do you understand by the terms environment, ecosystem and development? 1 Key themes to the study of Environmental Science are: • Human Population growth is the major contributor to environmental problems • Sustainability is the key to future availability of resources and environmental consequences • Global perspective is needed to solve many environmental problems • Industrial development and urbanization have serious environmental consequences • People and nature are interrelated and share a common history • Any solution to environmental issues requires consideration of both knowledge from science and values 2 Population Growth Most of the environmental problems (such as air pollution, waste generation etc) result from high population growth. An urban world has many negative impacts: •Rivers and coast lines are affected •Agricultural areas •Loss are affected of endangered species •Wetlands are filled in; and so forth. 3 Population Growth is causing the expansion of urban areas and industrial growth Also affecting sustainability: At present living environmental resources are being harvested more than its replenishment rate— what will happen in future? Can you define the following terms? • Sustainable resource harvest • Sustainable ecosystem 4 Understanding the concept of sustainable development • First defined in ‘Our Common Future’, a 1987 report of the World...

...They both Jump started the rise in population. The agricultural revolution happened first about 10,000 years ago. People began to grow crops, raise domestic animals, and live sedentary lifestyles. People began to live longer and produce more children. During the mid-1700s, the industrial revolution greatly increased population. It was a shift from an agricultural society to an urban society powered by fossil fuels. What is "the tragedy o the commons"? Explain how the concept might apply to an unregulated industry that is a source of water pollution? The tragedy of the commons was written by Garret Hardin. Hardin argued that unregulated exploitation would cause environmental depletion. What is environmental science? Name several disciplines involved in environmental science. Environmental Science is the study of how the natural world works and how humans and the environment interact. Environmental Science in an interdisciplinary field which requires expertise from ecology, earth science, chemistry, biology, economics, political science, demography, ethics, and others. Contrast the two meanings of science. Now name three applications of science. One description of science is a systematic process for learning about the world and testing our understanding of it. The term science is also commonly used to refer to the accumulated body of knowledge that arises from this dynamic process of observation, testing, and discovery.

...Running head: ENVIROMENTAL SCIENCE Environmental Science Star Heard ENV/100 July 14, 2012 Professor Restrepo Environmental Science When I hear Environmental Science I think of how science plays a role in the environment but the proper definition is Environmental Science is an interdisciplinary field that combines information from many disciplines, such as biology, geography, chemistry, geology, physics, economics, sociology (particularly demography, the study of populations), cultural anthropology, natural resource management, agriculture, engineering, law, politics, and ethics Berg and Hager (2009). Environmental Science is all about understanding the environment, how it works and how to protect it in the future. Science and technology has affected the environment for the good and bad. One thing that has been good for the environment is hybrid cars because it cuts out the toxins that other vehicles give off which is a whole lot better for the environment. Environmental sustainability is very important because we need to know the changes the environment goes and make changes where need be. I feel like this should be studied because the world is changing everyday and it is an important to know what’s going on. Air pollution is getting worse and by having somebody studying this they can find a solution and help improve air pollution. Mankind impact on Earth has really affected the way the world is today, this wasn’t internal but sometimes with technology there is a positive...

...University of Phoenix Material Environmental Science Worksheet Answer the following questions in at least 100 words. The answers are found in Ch. 1–4 of Environmental Science. 1. What would you include in a brief summary on the history of the environmental movement? The environmental movement was formed right around the end of the 1700’s. The movement itself didn’t become well known until maybe twenty or thirty years later. Between 1950 and 1957 there was a tremendous increase in the amount of people that became aware of the environmental movement’s ability to stop problems with the environment. Around the mid 1950’s, there were several catastrophic environmental disasters that occurred. Because there were access to radio and media at the time, it was easy for many people to see as well as hear all about the environment and the disasters that it involved, and this made a lot of people more “environmental friendly”. 2. Explain the main point concerning exponential growth and whether it is good or bad. Compare exponential growth to a logistic growth curve and explain how these might apply to human population growth. What promotes exponential growth? What constrains population growth? Our planet has many problems concerning the exponential growth of human life. Our main problem has become a great big problem to deal with, and I am sad to say that eventually our population will be so big that humans will not have enough resources in...
