1. Environmental Problems and Living Sustainably

2. Questions for Today: What are the major causes of Environmental Problem? What is poverty and affluence and how does it effect the environment? What are the three major worldviews when it comes to solving environmental problems? What are the Four Scientific Principles of Sustainability?

3. Causes of Environmental Problems The Five Major Causes of Environmental Problems, according to leading scientists and research are: 1. Population Growth 2. Unsustainable Resource Use 3. Poverty 4. Excluding environmental costs from market value 5. Insufficient knowledge of how nature works

4. Fig. 1-12, p. 18 Causes of Environmental Problems Population growth Unsustainable resource use Poverty Excluding environmental costs from market prices Trying to manage nature without knowing enough about it Stepped Art

5. Poverty and Affluence Poverty occurs when people are unable to meet their basic needs for adequate food, water, shelter, health and education. Poverty affects: Population growth affected Malnutrition Premature death Limited access to adequate sanitation facilities and clean water

6. Fig. 1-13, p. 18 2.6 billion (38%) Number of people (% of world's population) Lack of access to Adequate sanitation facilities Enough fuel for heating and cooking Electricity Clean drinking water Adequate health care Adequate housing Enough food for good health 0.86 billion (13%) 1 billion (15%) 1.1 billion (16%) 2 billion (29%)

7. Global Outlook on Malnutrition

8. Poverty and Affluence Affluence is the opposite of Poverty Harmful environmental impact due to High levels of consumption Unnecessary waste of resources Affluence can provide funding for Developing technologies to reduce Pollution Environmental degradation Resource waste

9. Ways to Solve Environmental Problems Environmental Worldview including environmental ethics Planetary management worldview We are separate from nature, that nature exists to meet our needs and wants. Stewardship worldview We can and should manage the earth for our benefit, but that we have an ETHICAL responsibility to be caring and be stewards of the earth. Environmental wisdom worldview We are a part of, and totally dependent on, nature and that nature exists for all species, not just us.
