Wind can cause erosion that changes the surface of the Earth. Wind erosion can have negative effects on the environment by removing soil and polluting the air during dust storms. What is one way to prevent wind erosion?

• People can drive off-road bikes across the desert.

• Ranchers can let their cattle graze in areas with little plant growth.

• Construction workers can wet the ground before driving on it or digging.

• Farmers can remove all plant material in the soil between planting seasons.

A refrigerator uses electricity to create a cold place to store food. What negative impact does refrigerator use have on the environment?

• The electricity needed to keep food cold can be expensive.

• If the electricity goes out, the food will spoil and make you sick.

In general, less energy is needed to produce a product from recycled material than from new material. This is one reason why we should recycle. Another reason to recycle is because _____________.

• recycling reduces the amount of resources available for our use.

• recycling reduces the amount of waste that is burned or buried in landfills.

One major contributor to global warming is an increased amount of carbon dioxide in the atmosphere. If the number of living plants significantly increased, ______________.

• global warming might get worse because of the increase in carbon dioxide caused by plants.

• global warming might be reduced because of the decrease in carbon dioxide caused by photosynthesis.

• global warming might get worse because of the increase in oxygen caused by plants.

• there might not be a noticeable impact on global carbon dioxide levels.
