Cleaning the Earth’s Air

Do you help clean your home? Maybe you vacuum dust from your floor. 你會打掃家裡嗎？像是用吸塵器吸家裡地板。 Hmmm… What can we do to help clean the Earth, everyone's home? The Earth's air has too much carbon dioxide. This is bad. Carbon dioxide makes the Earth warmer. It comes from cars, factories, and us! We breathe out carbon dioxide. 那我們該怎麼打掃我們的家園地球呢？空氣裡有太多二氧化碳讓地球更熱。汽車、工廠甚至是我們都會產生二氧化碳。 Well, we can't stop breathing! How about vacuuming? Some companies are vacuuming carbon dioxide from the air! 我們不能不呼吸，那如果把它吸走呢？有一些公司把二氧化碳從空氣中吸走。 These vacuums are VERY big. They cost a lot to make and use. 這種吸塵器很龐大，而且需要很高的成本製作跟使用。 The biggest vacuum now is in Iceland. Every day, it vacuums one hundred tons of carbon dioxide. Then the carbon dioxide goes down, down, down into the Earth. It becomes rock there! And it's there forever! This is good! 最大的吸塵器在冰島，每天會吸一百噸的二氧化碳到地底下變成岩石。 But… that's not very much carbon dioxide! Eight thousand cars make this much carbon dioxide. The air has a lot more carbon dioxide. 但是吸走的二氧化碳還不夠，8000台車就可以產生一百噸的二氧化碳。 Companies are building bigger vacuums! But we can't put vacuums everywhere! We have to make less carbon dioxide too! ---------------------------------------------------------------------------------------------------------------- Vocabulary 把空氣中的二氧化碳收集起來打進地底下，是不是很神奇? 1. too much 太多 Do you know that new bus terminal? 你知道那個新的公車總站嗎?
