Consumption of Natural Resources

Per-capita is:

• A unit of measurement that means “for each person”

• A unit of measurement that means “total”

• A device used to purify and clean water

• A device used to gather water from aquifers

Claim: the consumption of natural resources by humans has a negative impact on the environment. What data would provide evidence for this claim?

• Increased human lifespan and increased ice cap size

• Increased human population and decreased habitats for plants and animals

• Increased consumption of resources by humans and increased biodiversity (variety) in nature

• Increased of fossil fuel burning by humans and decreased use of other resources

Some factories that burn coal produce smoke with harmful chemicals, such as sulfur. Scrubbers are devices that are attached to the smokestacks to reduce the amount of sulfur put into the atmosphere. To evaluate the effectiveness of these devices, what data would need to be collected?

• The average amount of sulfur in a certain amount of coal

• The amount of coal a factory burns each year and how much sulfur it emits (produces)

• The increase in the use of scrubbers by factories that burn coal

• The amount of sulfur emitted (produced) by a smokestack before and after the scrubber is attached

Ths graph presents data from a city showing the amount of land used to bury solid waste each year. From 1990 to 1999, the amount of space needed to bury waste increased by 1 to 2 square kilometers per year. In the year 2000, the city started a recycling program to slow the increase of land needed for this burying this solid waste. The city claims that since this recycling program started, the amount of land needed for burying solid waste has decreased.

Which evidence would support this claim?

• Data showing that by the year 2010, more than 40% of the citizens were participating in the recycling program

• Data showing that the land used for burying solid waste in 2010 was less than 22 square kilometers

• Data showing that by the year 2010, there was five times more solid waste being buried than being recycled

• Data showing that the land used to build a recycling facility is greater than the amount of land used to bury solid waste

The fertilizers that farmers use to improve the growth of crops can result in excess nitrogen in water that flows into ponds and lakes. This sometimes results in a rapid growth of algae, called an algal bloom, killing fish. What data might be collected to monitor the amount of excess nitrogen in local water systems?

• The rate of crop growth

• The size of ponds and lakes

• The frequency of algal blooms

• The kinds of fish that eat algae
