Environmental Science and Ecology
| Question | Answer |
|---|---|
| What is environmental science? | The study of how humans can affect the environment. |
| What is ecology? | The study of relationship between living organisms and a environment. |
| What is natural capital? | On-earth resources (i.e. water, air soil, and nutrients) |
| What is sustainability? | The ability of Earth's natural systems and human cultural systems to survive and adapt to changing conditions indefinitely. |
| What are natural resources? | Matter and energy in nature that are essential or useful to humans. |
| What are natural services? | Functuions of nature that support life (i.e. nutrient-cycling and photosynthesis). |
| What is a solar capital- | Energy from the sun |
| What is Gross Domestic Product(GDP)- | Annual market value of all goods and services produced by all firms and organizations, foreign, and domestic, operating within a country. |
| If population grows, what should happen to the GDP? | It grows too |
| What do developed countries enjoy, beside higher standard of living? | A longer life expectancy, a decrease in infant mortality, greater food production than food needs, a decreased air and water pollution, and an overall decrease in poverty. |
| What percent of projected growth between 2008 - 2050 is expected to occur in developing countries? | 97% |
| What are renewable resources? Give three examples | Well-replenished resources (i.e. solar energy, fresh air, forests, grasslands, etc.) |
| What are nonrenewable resources? | Resources that are endangered in depletion (i.e. coal, petroleum, and natural gas). |
| What is the highest rate at which a renewable resource can be used indefinitely without reducing its available supply? | Sustainable yield |
| What is the tragedy of the commons? | Each user of an open access resource believes his/her contributiuon/use is not going to make a difference. There is great failure to consider that combined actions of many have a huge impact on the system. |
| What does the suggestions for sustainable use include? | Reycling, reusing, and reducing |
| What are the three unwanted effects of pollution? | 1.)Distrupts or degrade life-support systems 2.) Damage wildlife, human health, and property 3.) Create nuisance, such as noise, and unpleasant smells, tastes, and sights |
| What are the disadvantages of output controls? | They are only short-lived solutions, costly, and often transfer pollutant into another area. |
| What are the basic causes of environmental problems? | Population growth, unsustainable (& wasteful) resource use, poverty, poor environmental accounting, and ignorance of natural systems |
| What is the disadvantage of affluence? | Consumes alot and wastes alot |
| What is the advantage of affluence? | Development of technology |
| What are the four principles of sustainability? | Reliance on solar energy, biodiversity, nutrient cycling, and population control |
| What result from the impoverished country's efforts to meet their short-term needs? | Degradation and depletion of soils, forests, grasslands, fisheries, and wildlife |
