雅思口语Part3: What would happen when some species disappear on earth? 如果一些物种在地球上消失了会怎样?

我觉得很多事情会变得很糟糕。如果地球上的一些物种比如某种鸟类灭绝了，整个生活连都会被破坏。破坏了生物链，我们的环境也会收到影响，比如植物缺乏营养，洪水泛滥等等。

Things would happen in a terrible way I assume. If the species on earth like some type of birds that catch the worms came to extinction, the entire biologic chain would be broken. This article is from Laokaoya website. This would result in some unpredicted damages to our environment like malnutrition of the plants, flood and something like that.
