3Reading · Choose Clean Energy
🎧 Audio 43 · Reading: Choose Clean Energy and Help Curb Global Warming
Read the whole passage. Focus on practical ways people can reduce the negative impact of fossil fuels.
Main idea
Fossil fuels such as oil, coal, and natural gas provide energy for our cars and homes, but they increase the amount of carbon dioxide (CO₂) in the air, contributing to climate change in the form of global warming. However, there are choices we can make that can lessen their negative impact on the environment.
Get moving
Take good care of your car and keep your tires properly inflated with air. You will use less gasoline and save money. Better yet, skip the drive and walk, take public transportation, or ride a bicycle when you can.
Upgrade
Replace your old refrigerator or air conditioner with a new energy-efficient model. Not only will you save money on your electric bill, but you’ll contribute to cutting back on the pollution that causes global warming.
Cut back
Try to reduce the amount of water you use for showers, laundry, and washing dishes. And turn the temperature on your hot water heater down.
Recycle
Use products that are recycled from old paper, glass, and metal to reduce energy waste and pollution by 70 to 90%. And before you toss things in the garbage, think about what you can reuse.
Think local
Shipping foods over long distances is a waste of energy and adds to pollution. In addition, the pesticides and chemicals used to grow them are bad for the environment. So buy locally grown fruits and vegetables instead.
Speak out
Talk to lawmakers about your interest in curbing global warming. Support their attempts to improve standards for fuel efficiency, to fund renewable and clean energy solutions, such as wind and solar power, and to protect forests.
The effects of global warming
an increase in floods, droughts, tornadoes, and other extreme weather conditions
a rise in sea levels, causing flooding in coastal areas
higher sea surface temperatures, endangering fish life
the shrinking of glaciers, leading to a decrease in fresh water for farms and less energy production
a loss of tropical forests, an increase in wild lands, more forest fires, and a loss of animal and plant species
a decrease in agricultural yields, leading to famine
