Environmental Science Review

In order for a country to progress from a LDC to a MDC the country would have to

Increase rate of population growth

Raise the per capita income

Move from industry to agriculture economy based

Increase their unskilled labor force

Which of the following factors is as important as population in determining the environmental impact of humans

Climate of region

Level of resource consumption

Wealth of the nation

Amount of pollution produced

Renewable resources are

Resources such as fossil fuels that replenish within a resonable duration on the human time scale

Resources such as fish that can be replaced by natural processes on a fairly rapid scale provided they are not over exploited in the short term

Resources such as forests that are impossible to over exploit as trees grow so fast

Resources such as minerals because we can efficiently extract, refine, and recycle them

I = P * A * T Model can be used to calculate which of the following

Level of urbanization

People over population

Rates of industrialization

Human impact on the environment

How does science obtain knowledge about the world

By interactive process of experimentaion which refines hypothesis until they're finally proven to be the absolute truth

By relying on scientific authorites and the massive amounts of knowledge already obtained to explain new data

By systematically gathering evidence and disgarding potential explanation that do not fit the evidence and refining those that do fit the evidence

By conducting experiments designed to support hypothesis as being correct beyond reasonable doubt

How would a scientist respond to the statement "The theory of natural selection is just an educated guess at what is happening"

She would agree because theories are really just guesses about the scientific world

She would disagree because scientifc theories refer to broadly concieved well supported explanation of scientific phenomenon

She would agree because there is not enough support to accept the hypothesis of natural selecton

She would use the scientific method to conduct her own experiment to test the theory before accepting it as a fact
