Environmental Problems
• Population growth • Wasteful and unsustainable resource use • Poverty • Failure to include environmental costs of goods and services in market prices • Too little knowledge of how nature works • People with different environmental worldviews often disagree about the seriousness of environmental problems and what we should do about them. Causes Of Environmental Problems
Causes Of Environmental Problems
Percentage of World‘s Population Population growth Wealth and income Resource use Pollution and waste 18% 77 years 0.1% 85% 15% 88% 12% 75% 25% Life expectancy 82% 1.5% 66 years :
Harmful Results Of Poverty
• Understand our environment • Practice sustainability Solutions
• Environment is every thing that effects living organisms. • Ecology is biological science that studies relationship between living organisms and their environment. What Is Environment?
• In ecology, sustainability is how biological systems remain diverse and productive. Long-lived and healthy wetlands and forests are examples of sustainable biological systems. In more general terms, sustainability is the endurance of systems and processes. What Is Sustainability
• Perpetual • Renewable Resources • Non-Renewable Resources Resources
• Renewed continuously on human scale. -Solar energy -Wind energy Perpetual Resources
Sustainable Yield: the highest rate at which a renewable resource can be used without reducing its supply. Example: over-farming the land leading to soil erosion, clear-cutting forests. Environmental Degradation: when we exceed the natural replacement rate of the resource. Example: groundwater depletion, water pollution Renewable Resources (can be depleted or degraded)
Degradation of renewable free-access resources. “If I do not use this resource, someone else will. The little bit I use or pollute is not enough to matter, and such resources are renewable anyway.” Solutions? Tragedy of Commons
• Exist only in fixed quantities on earth. • Metallic resources (iron, copper, aluminum) • Non-metallic resources (salt, clay, sand) • Energy Resources (coal, oil , natural gas) When 80% is gone It may be too Costly to get last 20%. Non-Renewable Resources
Reduce: Use less resource Reuse: To use the resource more than once to conserve. Recycle: collecting resource, processing it into new products. Saving non-renewable resources

What is an Environmentally Sustainable Society • Our lives and economies depend on energy from the sun (solar capital) and natural resources and natural services (natural capital) provided by the earth. • Living sustainably means living off earth’s natural income without depleting or degrading the natural capital that supplies it.
How an environmentally sustainable society grows economically • Societies can become more environmentally sustainable through economic development dedicated to improving the quality of life for everyone without degrading the earth’s life- support systems.
Four Scientific Principles Of Sustainability • Nature has sustained itself for billions of years by using solar energy, biodiversity, population regulation, and nutrient cycling – lessons from nature that we can apply to our lifestyles and economies.
