季节森林 Forest
Trees are earth's largest organisms and are also one of the planet's oldest inhabitants. Seasonal forests (unlike tropical rain-forest) the largest land habitats. A third of all trees grow in the endless taiga of the Arctic north. Northern America has forests that include California's sequoia's, the earth's largest trees. There and elsewhere, their vast production of photosynthesis and shade presides over a seasonal cycle of life and involves countless plant and animal species.
树木是地球最大的制氧机器，也是这个星球上最古老的居民。季节森林，比如我们熟悉的热带雨林，是陆地上生物最大的栖息地。泰加林的树木数量占据全球树木总量的三分之一；而北美森林中的加州水杉，是地球上最巨大的树木。这些林地光合作用为这个星球制造氧气，也同时为无数的动植物提供了生生不息的生存庇护。
