海岸红杉是地球上现存最高的树木,也是地球上最古老的生物之一。它们曾一度遍布于加利福尼亚州的海岸,但现如今只剩下不到原始面积的十分之一。

1There is nothing like a coast redwood.It is the planet's tallest tree, up to heights of more than 320 feet into the sky.With trunks (树干) that grow to more than 27 feet wide, they can live for over 2,000 years.Some of them living today were alive during the time of the Roman Empire.

2Coast redwoods have survived through thousands of years of natural floods, droughts,tsunamis and fires.They can thrive and recover from damage as long as they can count on rainwater and coastal fog banks that roll in every morning.And it is those critical water sources that are disappearing as temperatures continue to rise.The damp conditions the trees like are rarer than they used to be.Coast redwoods now occupy less than 10 percent of their original range.

3Their loss will have some consequences, particularly in the vast amount of carbon they store.Redwoods can store 2,600 metric tons of carbon per hectare, more than double the absorption rate of the Pacific Northwest's conifer trees(针叶树), according to a new research published inForest Ecology and Management.

4David Milarch, an arborist (树木研究者) from Michigan, says he feels sorrowful about the disappearing redwoods.He spends his days tracking down the healthiest coast redwood specimens he can find, cloning them in his own lab, and then planting them in carefully chosen places where they can thrive.Milarch's goal is both to strengthen the coast redwood gene pool with clones of the strongest individuals, and to store loads of carbon.It's a complicated mission with a simple philosophy: save the big trees, and they'll save us.

5Milarch explains that we need a practical and measurable solution to fight against climate change.He believes the redwoods are the answer.However,scientist Mark Maslin cautions against viewing tree planting as a magic bullet,since even fast-growing trees take a long time to grow and be mature enough to reach their maximum carbon-trapping time which climate change cannot afford.As a global society, the most important thing we should do now is to reduce our overall carbon emissions if we want to have any impact on the planet's climate crisis.

Ⅱ.Difficult sentence in the text

However, scientist Mark Maslin cautions against viewing tree planting as a magic bullet, since even fast-growing trees take a long time to grow and be mature enough to reach their maximum carbon-trapping time which climate change cannot afford.然而,科学家马克·马斯林警告说,不要把植树看作一粒灵丹妙药,因为即使是快速生长的树木也需要很长时间才能生长并且成熟到足以达到最大的碳捕集时间,这是气候变化无法承受的。
