1. Chapter 2: Environmental Protection and Sustainable Development

2. 2.1 Environmental Protection and Sustainable Development  Increasingly, environmental protection is being incorporated into all human actions and into the process of development.  Meeting our needs while protecting the environment is called sustainable development. © FloridaStock/ShutterStock, Inc.

3.  Environmental protection has evolved from piecemeal local efforts to a much more comprehensive global strategy covering a wide assortment of environmental problems.  This involves high levels of cooperation among states and nations FIGURE 1 The evolution of environmental protection The Evolution of Sustainable Development

4.  Although environmental policy and protection efforts have evolved dramatically in the past three decades, most solutions dealt with symptoms.  Efforts are now under way to address the root causes of the problems. The Next Generation of Environmental Protection Efforts

5. 2.2 Meeting Human Needs while Protecting the Environment  What Is Sustainable Development?  Sustainable development = a means of meeting present needs without preventing future generations and other species from meeting theirs.  The environment is essential to satisfying the needs of present and future generations.  Environmental protection is a key to its success.

12. Japan's next leader has promised a big cut in greenhouse gas emissions, saying he will aim for a 25% reduction by 2020 compared with 1990 levels. Democratic Party leader Yukio Hatoyama is due to take over as prime minister on 16 September, after a resounding election victory in August. His predecessor, Taro Aso, had pledged cuts of only 8%. Mr Hatoyama said the plan was dependent on other nations agreeing targets at December's climate talks in Copenhagen. http://news.bbc.co.uk/2/hi/science/nature/8241016.stm

13. 2.3 Human Settlements: Networks of (Unsustainable) Systems  Human settlements are made up of many interdependent systems, such as:  Transportation  Energy  Waste management

14. Human Settlements  Growing evidence shows that these systems are not sustainable in the long run. FIGURE 8: Human systems

15. 2.4 What’s Wrong with Human Systems  Although human systems may provide us with a steady stream of goods and services, they are systematically reducing the planet’s carrying capacity.  Human systems: 1. Produce pollution in excess of the planet’s ability to absorb and detoxify wastes 2. Deplete nonrenewable resources faster than substitutes can be found 3. Use renewable resources faster than they can be regenerated

16. FIGURE 11: Unsustainable systems

17.  To create a sustainable future, we must revamp the systems that support our lives.  The challenge is twofold:  to retrofit existing systems to make them as sustainable as possible  to build new systems using the principles of sustainable design The Challenges Ahead
