Why are plants important?
植物為什么那么重要?
Air 空氣
Plants take in carbon dioxide (二氧化碳) and make oxygen (氧氣) humans and animals need. Plants make 98% of the oxygen we breathe.
植物吸收二氧化碳,釋放人類和動物所需的氧氣。我們呼吸的氧氣有98%都是植物給我們的哦!
Food 食物
The world’s food supply (供應(yīng)) depends on about 150 plant species. Just 12 plant species provide three-quarters of the world’s food.
世界糧食供應(yīng)主要依靠150種植物——僅12種植物就提供了世界人們所需食物的四分之三。
Habitat 棲息地
Plants provide habitats for animals and humans. Rainforests (雨林) only cover a small part of Earth’s surface, yet they contain (容納) more than half of the known species of animals and plants.
植物為動物和人類提供棲息地。雖然熱帶雨林在地球所占面積并不大,但它們卻容納了地球超一半的動植物。
Climate 氣候
Plants balance our climate. They help take carbon dioxide out of the atmosphere, which can slow down global warming.
植物可以平衡氣候。它們可以從大氣中吸收二氧化碳,從而減緩全球變暖。
Health 健康
A 2015 study showed that indoor plants can reduce stress. Plants can also help you stay focused (精力集中的) and work efficiently.
2015年的一項研究表明,室內(nèi)植物可以減輕壓力。植物還可以幫助你保持專注,提高工作效率。
