As butterflies land on flowers, the pollen from the flower clings to their legs and then comes off again on the next flower they land on.

當蝴蝶停在花朵上時，花朵上的花粉會附著在它們的腿上，然後它們停在下一朵花時又會脫落下來。

This is called pollination.

這就是所謂的授粉。

We need butterflies to pollinate plants and flowers, so that new plants and flowers are able to grow as they are food for people as well as other insects and animals.

我們需要蝴蝶為花草授粉，這樣新的花草才能生長，因為它們是人類以及其他昆蟲和動物的食物。

We need plants for more than just food though, they are a very important part of how the earth works and they help keep our air nice and clean.

我們需要植物不僅僅是為了食物，它們是地球運作中非常重要的一部分，而且它們有助於保持我們的空氣良好和乾淨。

Green plants use energy from sunlight to help them grow.

綠色植物利用太陽光的能量來幫助它們生長。

While they're using this energy, they make the fresh air that people and animals need to breathe.

當它們使用這些能源時，它們製造了人類和動物需要吸取的新鮮空氣。

Because of this, plants are very important to the environment, just as well butterflies enjoy hopping from flower to flower because they're doing a brilliant job at the same time.

正因為如此，植物對環境是非常重要的，就像蝴蝶喜歡從一朵花跳到另一朵花一樣，因為它們同時也在做著出色的工作。
