What is one reason it is so important that we start using renewable resources instead of nonrenewable resources?
they are less expensive
they are essentially 'infinite'
they increase air pollution

to generate heat and electricity
These are all examples of...
renewable resources
nonrenewable resources
fossil fuels
greenhouse gases

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 burning of fossil fuels by humans and decreased use of other resources
According to the chart, the type of energy responsible for the LEAST amount of greenhouse gas emissions is:
coal
hydropower

biofuels
hydroelectric
geothermal
wind
What is one disadvantage of coal?
Coal produces air pollution.
Coal is inexpensive
The world isn't using a lot of coal which makes it an undesirable job.
You can only use it to roast hot dogs and cook hamburgers.
What is one disadvantage of renewable energy?
Electricity and power could become much cheaper.
Third world countries could have affordable energy.
Many people could become energy independent.
Most sources are expensive to get started.
What can you infer about fossil fuels from their name?
They emit harmful gases when burned.
They've been buried in the earth's crust for millions of years.
They're the most abundant energy source on the planet.
They're used to make gasoline.
Which of the following is a true statement about fossil fuels?

Which of these is an advantage of fossil fuels?
You can extract them without complicated machinery.
They are relatively inexpensive to produce.
Burning them does not have any negative side effects.
There is an unlimited supply of them.
