Environmental Science AP 2012 - 2013 PACIFICA High School Instructor: STEVE DOUCETTE Semester I: Chapters 1-16, 28, 29, and 30 Study Outlines: 61 pages The Semester I Final will cover all 19 chapters listed above. Please plan on 250-300 multiple-choice questions, with the Final Exam point total being scaled to = 20% of the semester grade, - - a fairly traditional comprehensive final relative point value. As you know, you’ll have 2 hours to complete the exam. 1 Chapter Study Outlines Chapter 1: Part I 1. Noteworthy Environmental Science themes: a. People & Nature: People and Nature are intimately connected; human survival depends on the environment. b. Rapid human population growth: - is generally considered to be a (“the”) fundamental environmental issue/topic/challenge. c. Sustainability: Human survival and human-built systems (e.g., an urban area), like natural systems, depend on sustainable systems. d. Human environmental impacts: Humans have had an impact on the environment for millions of years. e. Urban environments: Approximately 50% of the global population lives in cities, and it is projected that about 65% of the global population will live in cities by the year 2025. f. Science and Values: Value judgments based on scientific knowledge: Solutions to environmental challenges typically involve making value judgments based on scientific knowledge. Environmental problems or challenges have a cultural and social context, and understanding the role of cultural, social, and economic factors is vital to the development of solutions. g. Precautionary Principle: This principle implies that there is a social responsibility to protect the public from exposure to harm when scientific investigation has found a plausible risk, even though an exhaustive body of scientific evidence may not exist at the time that a decision is made or could be made. 2.

Policy Instruments (above) Source: The World Health Organization http://www.who.int/heli/economics/econinstruments The common element of all economic instruments is that they effect change or influence behavior through their impact on market signals. Economic instruments are a means of considering "external costs," i.e. costs to the public incurred during production, exchange or transport of various goods and services, so as to convey more accurate market signals. Those external costs may include natural resource depletion, environmental degradation, health impacts, social impacts, etc. Economic instruments facilitate the implementation of Principle 16 of the Rio Declaration, commonly known as the "Polluter Pays Principle." The article states: "National Authorities should endeavor to promote the internalization of environmental costs and the use of economic instruments, taking into account the approach that the polluter, should in principle, bear the cost of pollution with due regard to the public interest and without distorting international trade and investment." Methods: Economic Instruments can be designed in a variety of ways, and for a variety of applications, including the following: Increasing prices of goods and services that damage health and environment, as well as increasing financial returns in the case of more sustainable approaches that foster more environmentally- friendly production and consumption patterns. Reduction of compliance costs by providing flexibility to polluters or users of natural resources to chose the most cost-efficient and environmentally-effective measures. Incentives for investments in innovation and improved environmental technology so that both environmental and financial benefits are generated. 14 Allocation of property rights and responsibilities of firms, groups or individuals in a manner so that they have both the incentive and the power to act in a more environmentally- responsible manner. The raising of revenues to achieve environment and health objectives via tax policies. Relevance to policy-making Economic instruments are often contrasted to "command and control" policy approaches that determine pollution reduction targets and define allowable control technologies via laws or regulations. In reality, however, command and control policy and economic instruments frequently operate in tandem. A government may set limits on permitted pollution levels for a region or a country in order to meet a certain health or environment objective. Market-oriented approaches such as tradable permits might then be used to allocate the allowable emissions in an efficient manner. Tax breaks or other financial incentives might be offered to groups, individuals or industries investing in cleaner technologies. ___________________ ____________________ Systems of Change: The Big Picture Chapter 3 Environmental Science AP Instructor: Ben Smith Big Ideas and Supporting Material related to Ch.3: 1.

In 1999, the USFWS approved two new approaches which strive to better protect E/T species on private land: SHAs: landowners Voluntarily agree to take steps to restore, improve, or maintain habitat for E/T species on their land; in return, landowners get tech help from conservation agencies, gov’t assurances that the land, water, and other natural resources involved will not face future restrictions; CCAs: landowners agree to take specific steps to help conserve a species which is declining but is not yet listed as E/T; no additional restrictions can be placed on the landowner if the species is listed 77.
