The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:
1. Get a reusable water bottle
Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.
2. Eat less meat
You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.
3. Switch to energy-efficient light bulbs
Most households use standard incandescent (白炽的) bulbs. But compact fluorescent (荧光的) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.
4. Buy organic and local food
Did you know that only 1 percent of pesticides (杀虫剂) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.
5. Recycle your electronics
Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (有毒的) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.
72. The readers of this passage are called on to ______.
A. help reduce global warming               B. use water in a wise way               C. donate money for charity                      D. keep a balanced diet
73. What is an advantage of CFLs according to the passage?
A. They use more energy but produce more light.                                   B. They can last longer so don't need to be replaced often.                                        C. They cost less than standard incandescent bulbs.                                         D. They are as energy-efficient as incandescent bulbs.
74. Which of the following figures is correct according to the passage?
A. Every year an American buys 63 plastic water bottles on average.                   B. Eating meat one day less a week helps cut environment costs.                                   C. 99 of the pesticides used on crops is effective in practice.                                         D. Electronics account for half of poisonous heavy metals on the earth.
75. Which can be the best title for this passage?
A. Why is the earth getting warmer?           B. What can we do about pollution?              C. How can you lead a greener life?          D. Who is to blame for global warming?
