Forests give us shade,quiet and one of the larder callenges in the fight against climate change.Even as we humans count on forests to soak up a good share of the carbon dioxide we produce,we are threatening their ability to do so.The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.Thankfully,there is a way out of this trap-but it involves striking a subtle balance.Helping forests flourish as valuable“carbon sinks”long into the future may require reducing their capacity to absorb carbon now.California is leading the way,as it does on so many climate efforts,in figuring out the details.The state’s proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest.This temporarily lowers carbon-carrying capacity.But the remaining trees draw a greater share of the available moisture,so they grow and thrive,restoring the forest’s capacity to pull carbon from the air.Healthy trees are also better able to fend off insects.The landscape is rendered less easily burnable.Even in the event of a fine,fewer trees are consumed.The need for such planning is increasingly urgent.Already,since 2010,drought and insects have killed over 100 million trees in California,most of them in 2016 alone,and wildfires have burned hundreds of thousands of acres.California plans to treat 35,000 acres of forest a year by 2020,and 60,000 by 2030-financed from the proceeds of the state’s emissions-permit auctions.That’s only a small share of the total acreage that could benefit,about half a million acres in all,so it will be vital to prioritize areas at greatest risk of fire or drought.The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels.New research on transportation biofuels is already under way.State governments are well accustomed to managing forests,but traditionally they’ve focused on wildlife,watersheds and opportunities for recreation.Only recently have they come to see the vital part forests will have to play in storing carbon.California’s plan,which is expected to be finalized by the governor next year,should serve as a model.
  What is essential to California’s plan according to Paragraph 5?《》()

A.To handle the areas in serious danger first.
B.To carry it out before the year of 2020.
C.To perfect the emissions-permit auctions.
D.To obtain enough financial support.

We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long age. My wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions(排放)of carbon dioxide(CO2)and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment. For one month we recorded our personal emissions of CO2. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭)produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化)of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO2 emissions by 80 percent,” he said.

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

72. Why did the author and his wife try a new diet?

A. To take special kinds of food B. To respond to climate change.

C. To lose weight D. To improve their health
