Nature’s Lungs

We know that trees are nature’s purifier (净化器): They absorb carbon emissions (碳排放)and release oxygen. But their     1       (able) to do that changes as they age. According to Newsweek, trees     2       are at least 20 years old can absorb carbon better than younger ones and older ones. And a recent study by researchers from South Korea’s Forest Research Institute     3       (find) exactly how much carbon that each 25-year-old cherry tree can absorb: 20 pounds (9.1 kilograms) each year.

According to the study, there are     4       (current) about 1.5 million cherry trees in South Korea, which means they can take in as much as 13,650 tons of carbon each year.

This may sound like a lot,     5       it’s only the annual emissions of 6,000 cars. And it’s pretty     6       (shock) if you think about it: The annual emissions of a single-car requires 250 mature cherry trees to absorb     7       carbon.

Yet, planting trees is still considered the most effective way     8       (reduce) global warming, according to Professor Tom Crowther of the Swiss university ETH Zurich. “Forest restoration isn’t just one of our climate change     9       (solution), it’s the top one,” he told the Guardian. “What blows my mind is the scale. I thought restoration would be in the top 10, but it is much    10     (powerful) than all of the other climate change solutions proposed.”

2 . On Sunday night, the police found a baby koala in a bag in the town of Wishart in Queensland, Australia, during a traffic stop. Queensland police spokesperson Michael Beatty said that the officers asked a 50-year-old driver if she had anything to report. She then told the officers that she had a baby koala in her bag.

“Not quite believing their ears, the officers cautiously opened the bag and found this lovely boy and we’ve called him Alfred,” the spokesperson said. “The young koala is about 6 months old and weighs 1.5 kg. It appears to be healthy, though it was very thirsty.”

The police are warning people who find koalas to turn them over to authorities, rather than try to take care of them themselves. Koalas are protected in parts of Australia, including in Queensland, where they have been listed as “threatened” under the Nature Conservation Act.

Of course, koalas are also violent animals. One particularly wild koala even attacked a farmer in South Australia when she was riding along a muddy road.

“As it started running towards me, I thought I’d better speed up,” the terrified farmer told reporters. “But the road was too muddy, So I abandoned my bike and ran away. Fortunately, it ran up and attached itself to the dirty wheel — perhaps mistaking it for a eucalyptus tree.”

Deakin University biologist Desley. Whisson has some tips in case you experience this predicament. “Koalas more generally run from than to people. The farmer did the right thing by moving away from her bike,” she said. “The best advice I can give to people is to not fight with a koala displaying unusual behaviour. Make sure that there is another object between you and the koala so that it can’t climb you. Or you can just simply run. Their fingers are very sharp.”

She also believed the koala might have been confusing the sound of the bike with that of a koala mate.
