V.阅读理解

Have you ever wondered how many ants there are on Earth? Scientists at the University of Hong Kong certainly have studied it. In a new study, they counted the number of the world’s ants and it is about 20,000,000,000,000,000 (20 with 15 zeroes)! That means for every human, there are nearly 2.5 million ants.

How did they count such a big number? In the past, many scientists counted ants in different areas. They collected fallen leaves and earth and dried them to force the ants to come out for counting. Based on 465 studies that cover all lands, the new study made the number.

According to Wang Runxi, one of the scientists, the number and distribution (分布) of ants can be valuable predictors (预测器) of environmental changes. “Ants play an important role in the ecosystem,” Wang told Science and Technology Daily. “They help loosen (松) the soil, spread seeds of plants, break down things and form a part of the food chain (食物链). They are everywhere on Earth except for the coldest places.”

“Compared with big animals, little ants have more feelings to environmental changes.” Wang added. Most ants live in high-temperature areas. But in recent years, ants have been moving toward cold places because of global warming (全球变暖). Changes in forests, such as too much cutting, also have an influence on the number of ants, the study showed.

“Our global map of ants allows us to better understand and predict ants’ responses to worrying environmental changes.” scientists wrote in the study.
