Chapter 10 Ecology and Sustainable Development in Global Business McGraw-Hill/Irwin Copyright © 2011 by The McGraw-Hill Companies, Inc. All rights reserved. Ch. 10: Key Learning Objectives Defining sustainable development Understanding the obstacles to developing the world’s economy to meet the needs of the present without hurting future generations Assessing the major threats to the Earth’s ecosystem Recognizing the ways in which population growth, inequality, and industrialization have accelerated the world’s ecological crisis Examining common environmental issues that are shared by all nations Analyzing the steps the global business community can take to reduce ecological damage and promote sustainable development 10-2 Ecological Challenges Ecology The study of how living things – plants and animals – interact with one another in an ecosystem By some measures the demands of human society have already exceeded the carrying capacity of the earth’s ecosystem Global Commons A commons is a shared resource that a group of people uses collectively Paradox that if all individuals maximize their own advantage in short term, commons will be destroyed 10-3 Ecological Challenges Preserving our common ecosystem and assuring its continued use is a new imperative for business, government, and society Sustainable development Development that meets the needs of the present without compromising the ability of future generations to meet their own needs • Protecting the environment will require economic development • Economic development must be accomplished sustainably Sustainable development is an appealing idea but also a controversial one 10-4 Threats to the Earth’s Ecosystem Sustainable development requires that human society use natural resources at a rate that can be continued over an indefinite period Renewable resources (water, forests) can be naturally replenished Nonrenewable resources (fossils fuels like oil, coal) once used are gone forever Examples of natural resources that are now being depleted or polluted at well above sustainable rates Water resources Fossil fuels Arable land 10-5 Forces of Change Accelerating Ecological Crisis Pressure on the earth’s resource base is becoming increasingly severe Three critical factors have combined to accelerate the ecological crisis facing the world community and to make sustainable development more difficult Population explosion World income inequality Rapid industrialization of many developing nations 10-6 Figure 10.1 World Population Growth 10-7 Figure 10.2 World Income Distribution by Deciles (Tenths) of the Population, 2000 10-8 The Earth’s Carrying Capacity The world resource base is essentially finite, or bounded Limits to growth hypothesis suggests human society is overshooting earth’s carrying capacity, with drastic consequences if changes are not made 10-9 The Earth’s Carrying Capacity One method of measuring the Earth’s carrying capacity, is called the ecological footprint The amount of land and water a human population needs to produce the resources it consumes and to absorb its wastes, given prevailing technology 10-10 How Can Human Society Bring the Earth's Carrying Capacity Back into Balance? This is without a doubt one of the great challenges facing the world’s people. Any solution will require change on many fronts: Technological innovation – Develop new technologies to produce energy, food, and other necessities of human life more efficiently and with less waste Changing patters of consumption – Individuals and organizations concerned about environmental impact could decide to consume less or choose less harmful products and services “Getting the prices right” – Some economists have called for public policies that impose taxes on environmentally harmful products or activities 10-11 Global Environmental Issues Ozone depletion A bluish gas, composed of three bonded oxygen atoms, that floats in a thin layer in the stratosphere between 9 and 28 miles above the planet 1974 – Scientists chlorofluorocarbons (CFCs) could react with and destroy ozone 1985 - Scientists discovered a thin spot, or hole, in the ozone layer over Antarctica 1987 - A group of nations negotiated the Montreal Protocol, agreeing to cut CFC production, agreement later amended to ban CFCs (This is an example of world governments coming together to address an environmental threat) • As of 2009, 195 countries had signed the protocol The protective layer will gradually recover if regulatory trends continue 10-12 Global Environmental Issues Global warming Greenhouse effect occurs when carbon dioxide and other gases in the atmosphere prevent heat from escaping into space Since the Industrial Revolution, the amount of greenhouse gases in the atmosphere has increased by as much as 25% Caused mainly by the burning of fossil fuels such as oil and natural gas If societal emissions of these gases continue to grow unchecked, the earth could warm by as much as 6.4 degrees Celsius by 2100 10-13 Figure 10.3 Global Warming 10-14 Causes of Global Warming and Carbon Dioxide Black carbon the sooty smoke that is created by the incomplete combustion of diesel engines and wildfires is the second largest contributor to climate change, responsible for as much as 18 percent of global warming Deforestation Trees and other plants absorb carbon dioxide and remove it from the atmosphere; therefore cutting down trees contributes to global warming Beef production Methane, a potent greenhouse gas, is produced as a by-product of the digestion of some animals, including cows CFCs Destroy the ozone and are also considered greenhouse gases 10-15 Global Climate Change Initiatives Kyoto Protocol Multination agreement in 1997, went in to effect in 2005 Requires industrial nations to reduce greenhouse gas emissions 5% below 1990 levels European Union has taken lead on reducing emissions As of 2006, 161 nations, representing 62% of world’s carbon emissions, had ratified U.S. has not ratified, citing harm to U.S. economy 10-16 More Global Environmental Issues Decline of biodiversity Refers to the number and variety of species and the range of their genetic makeup Scientists estimate that species extinction is occurring at 100 to 1,000 times the normal, background rate due to pollution and habitat destruction A major reason for the decline in the earth’s biodiversity is the destruction of rain forests Only half of the original tropical rain forests still stand Rain forests destruction is ironic because they may have more economic value standing than cut 10-17 More Global Environmental Issues Threats to marine ecosystems Refers to oceans, salt marshes, lagoons, and tidal zones that border them, as well as diverse communities of life they support Salt water covers 70 percent of the earth’s surface and supports many species Key categories of threats to these ecosystems • Fish populations • Coral reefs • Coastal development 10-18 Response of the International Business Community World Business Council for Sustainable Development One of leaders in effort to promote sustainable business practices Made up of 200 companies representing more than 35 countries and 20 industries Goal to encourage high standards of environmental management and to promote closer cooperation among businesses, governments, and other organizations concerned with sustainable development Promotes eco-efficiency and has documented competitive advantages for companies • Those that added the most value with the least use of resources and pollution were more competitive and environmentally sound 10-19 Voluntary Business Initiatives Life cycle analysis Involves collecting information on the lifelong environmental impact of a product, from extraction of raw material to manufacturing to its distribution, use, and ultimate disposal Industrial ecology Refers to designing factories and distribution systems as if they were selfcontained ecosystems Extended product responsibility Companies have a continuing responsibility for the environmental impact of the products and services, even after they are sold Carbon neutrality An organization or individual produces net zero emission of greenhouse gases; this is usually accomplished by a combination of energy efficiencies and carbon offsets 10-20 Codes of Environmental Conduct Some of the leading universal codes include the following: Business Charter for Sustainable Development – developed by the International Chamber of Commerce CERES Principles – developed by the Coalition for Environmentally Responsible Economies ISO 14000 – a series of voluntary standards developed by the ISO, an international group based in Switzerland Many executives are championing the idea that corporations have moral obligations to future generations 10-21
