LONDON: What could possibly be wrong with planting trees? The advantages are obvious; they firm the soil, soak up (摄取) extra water and take carbon dioxide (二氧化碳) out of the atmosphere.
However, it now turns out that planting trees could add to global warming.
Tree roots do a great job of keeping soil firmly on the ground and out of the wind’s power. The problem is that some of those dust clouds play an important part in soaking up carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface. The dust fuels oceanic life.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting programme there is successful and the dust supply reduced, the net result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work “shows clearly the complexity of the system and the importance of not tinkering(粗劣地修补) with it without understanding the results. For this reason there is the need to focus(集中) on cutting carbon dioxide giving off rather than monkeying (瞎弄) about with the land surface.”
An American scientist, Robert Jackson, has shown that when native grassland areas are invaded(侵入) by trees, carbon is lost from the soil. “We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees, ” says Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed(超过) by the loss of carbon from the soil below ground. Countries that plan to combat global warming by planting trees may have to think again. Solutions(解决办法) to environmental problems are often more complex than they first appear, and understanding the Earth’s climate is a very great challenge.

Andy Tomas is proof of the typical case that life-changing disaster awaits the drunken driver.
“A lot of teachers say, ‘Don’t drink,’ but I’m not going to say that, because I know that students are going to do it,” Andy says. “I just say, ‘Don’t get in a car.’”
As an 18-year-old, he could be a classmate or a friend, and that familiarity adds to the power of his words. He has spoken to more than 2500 high school students so far, and he has noticed their unusual silence.
One year ago, Andy, having been with friends drinking, lost control of his car and was thrown into trees 20 feet away. He was found covered in blood, with many bones broken. He was diagnosed with a severe brain injury and remained in an unconscious state and on life support for nearly three weeks. His skull was opened to reduce pressure on his brain.
At Children’s Specialized Hospital in New Brunswick, Doctor Erin Leahy initially found Andy unable to move the right side of his body. But by the end of his six-week stay, he was able to walk out of the building. Leahy called that an inspiration and a surprise.
Yet Andy’s recovery is incomplete. Brain and muscular therapy(治疗) has helped him regain movement in his right arm, but he still struggles with right hand.
In the process of recovery, Andy has thought deeply about what happened and why, and decided to share his story. Encouraged by his doctor, he began to attending meetings, delivering speeches.
He said he was nervous at first, but has grown used to the spotlight. “I feel like I know how to talk to people.” He said. And his recovery and visible injury help him draw serious attention from students.
Drunk driving, he tells students, is like playing gambles. “You might do it a bunch of times, but something is going to happen.”
Now his days are all about the therapy, work and going to the gym. Mentally, he says, “ I’m a lot happier in my life.”
