   Putting plastic bottles in a recycling bin Using old glass jars to store food Composting banana peels Buying a new reusable water bottle

   ✓ Using old glass jars to store food

3. What is the main benefit of recycling paper?

   It saves water used in manufacturing It reduces the need to cut down trees It creates more landfill space It generates less air pollution than making new paper

   ✓ It reduces the need to cut down trees

   Recycling paper significantly reduces the demand for virgin pulp, which means fewer trees need to be cut down for paper production.

4. What is 'composting'?

   Sorting trash into different bins Turning food scraps and yard waste into nutrient-rich soil Breaking down plastic bottles into new materials Washing and reusing plastic containers

   ✓ Turning food scraps and yard waste into nutrient-rich soil

5. Why is it important to conserve water?

   To make sure there's enough for industrial use To reduce the amount of electricity needed to treat and pump water To allow for more swimming pools to be built To make sure there's enough for car washes

   ✓ To reduce the amount of electricity needed to treat and pump water

   Conserving water saves energy because a lot of electricity is used to treat, pump, and heat water. Less water usage means less energy consumption.

6. What is a 'renewable energy source'?

   Energy that comes from burning coal Energy that comes from sources that are naturally replenished Energy that is used up quickly Energy that is very expensive to produce

   ✓ Energy that comes from sources that are naturally replenished

7. Which of these is NOT a renewable energy source?

   Solar power Wind power Natural gas Geothermal energy

   ✓ Natural gas

   Natural gas is a fossil fuel, which is a finite resource that is not replenished at a rate comparable to its consumption.

8. What does 'carbon footprint' refer to?

   The total amount of greenhouse gases produced by our actions The number of steps a person takes in a day The amount of plastic waste a person generates The energy used to power a single light bulb

   ✓ The total amount of greenhouse gases produced by our actions

   A carbon footprint is the total amount of greenhouse gases, primarily carbon dioxide, emitted directly or indirectly by an individual, organization, event, or product.

9. Why is planting trees considered a 'green' activity?

   Trees produce more oxygen than they consume Trees help absorb carbon dioxide from the atmosphere Trees provide shade, reducing the need for air conditioning All of the above

   ✓ All of the above

   Planting trees is beneficial because they produce oxygen, absorb CO2 (a greenhouse gas), and provide shade which can reduce energy consumption for cooling.

10. Which of the following actions helps reduce air pollution?

    Driving a car alone for short distances Using public transportation or carpooling Leaving lights and electronics on when not in use Burning leaves in the backyard

    ✓ Using public transportation or carpooling

    Using public transportation or carpooling reduces the number of individual cars on the road, which in turn lowers emissions and air pollution.
