Problems and Solutions
Problems: The pollution that causes acid rain comes from power
plants that make electricity. We use electricity for our lights,
heat, air conditioning, microwaves, computers, TVs, and many other
things we have in our homes. Some power plants burn fossil fuels
like coal—a black material from the earth—to make electricity.
When coal is burned it emits, or gives off, pollutants like sulfur
dioxide and nitrogen oxides. This is the pollution that causes acid
Pollution also comes from the cars we drive. People use cars to
go to work, school, the supermarket, vacations, shopping, friend's
houses, and other important places. The more gas people burn to
drive, the more pollution in the air. Some cars make less pollution
than other cars, but not everyone drives these kinds of cars.
One way to have less pollution is to use less electricity. If less
electricity is used, then less coal is burned, so there will be
Power plants can do things to make less pollution. When the coal
is burned, the power plants can take out some of the sulfur dioxide
and nitrogen oxides so they don't go into the air. Power plants
also can burn lower sulfur coal, or clean coal. This coal has less
sulfur in it, so less sulfur dioxide goes into the air.
Now that you are an acid rain expert, which ideas do you think
would work best to reduce the amount of pollution in the air around
- Power plants could use cleaner coal.
- Power plants could take out some of the pollution before it
goes into the air.
- People could use less electricity.
- People could use more electricity.
- People could turn off the lights when they are not in the room.
- People could drive less, or use buses or trains instead of cars,
to help keep the air clean.
- People could drive more.
- People could buy cars that put less pollution into the air.
- People could keep buying cars that put a lot of pollution into
