19.阅读题 Climate change may be a big problem, but there are many little things we can do to make a difference. If we try, most of us can do our part to reduce the amount of greenhouse gases that we put into the atmosphere. Many greenhouse gases come from things we do every day. As we have learned, these greenhouse gases trap energy in the atmosphere and make the Earth warmer. Driving a car or using electricity is not wrong. We just have to be smart about it. Some people use less energy by carpooling. For example, four people can ride together in one car instead of driving four cars to work. Why not try to do something to help make the planet a better place?
Save Electricity
Whenever we use electricity, we put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot. If you're leaving your computer for a while, put it on stand-by. You'll be able to restart it quickly, and it'll take less energy than shutting it down and then restarting it.
Bike, Bus, and Walk
You can save energy by sometimes taking the bus, riding a bike, or simply walking.
Plant Trees
Planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide from the air. Recycle Recycle cans, bottles, plastic bags, and newspapers. When you recycle, you send less trash to the landfill and you help save natural resources, like trees, oil, and elements such as aluminum.
When You Buy, Buy Cool Stuff
There are lots of ways we can improve the environment. One of the ways to reduce the amount of greenhouse gases that we put into the air is to buy products that don't use as much energy.
Take Corporate Action
Tell the companies you invest in that you care about global warming. Don't like a company's attitude on global warming? Go to shareholder meetings and speak up!
Knowledge Is Power
Learn everything you can about global warming. What is it? How does global warming work? Why is it happening? What are the causes? What are the critics saying? Find out all the answers! Join a national or local environmental group that is fighting the climate crisis every day, so their membership numbers swell and their voice has more power.
