問題詳情

▲ 閱讀下文，回答第 46 – 50 題     People are making lifestyle choices to reduce greenhouse gas emissions globally. Among greenhouse gases, carbon dioxide is the main reason for climate change and natural disasters, such as flooding and droughts. There are many things that we can do about our food, travel, and electricity to reduce the speed of global warming.   It is well known that the food system is responsible for at least 20 percent of greenhouse gases. A low carbon diet reduces emissions released from the production, packing, processing, transport, and preparation of food. It is recommended for one to buy organic food instead of eating imported, processed, and frozen foods. Eat only food which is in season or from your region. Avoid eating red meat and dairy products, which are the most emission-intensive foods. Other actions include eating a vegetarian diet and proper portion to reduce the waste of food.   The burning of gasoline to power vehicles that transport food over long distances by air, ship, truck, and rail releases a great amount of carbon dioxide. Walk, bike, carpool, or take mass transportation whenever possible. As a driver, prevent unnecessary idling of engines, avoid aggressive driving, rapid acceleration or sudden stops, and keep vehicles in good running condition.   Unlike incandescent bulbs, compact fluorescent lamps use 70 – 80 percent less energy and last at least 8 – 13 times longer. Other tips include turning off lights and appliances when they are not in use. Unplug cellular phone chargers when the battery is fully charged, and reduce the use of the dryer by hanging up your laundry on a clothesline.   We can slow down the climate change by making personal commitment to protect our planet, thereby avoiding the dangerous consequences of global warming. 的
