D
Nothing earns attention like rarity. In the natural world, rarity is most clearly represented by the last members of a declining species. These scarce (稀有的) plants and animals are extremely valuable; they represent the final hope for preventing extinction. The efforts toward conserving rare species have made an enormous difference. In the past few decades, declines of many endangered plants and animals have been reversed(逆转). But the attention to scarcity could come at the expense of overlooking the ordinary.
If we are to conserve nature, we must maintain our focus on the familiar. Increasingly, conservation is turning its sights in this direction—to safeguard what is common, not just what is rare.
There are good reasons to consider the common. A study of North American birds uncovered that we have lost three billion birds on this continent within the past two generations.
These declines include species once considered widespread and secure, like the common redpoll, whose numbers are down by 29 million and the common nighthawk, down by 26 million. The shocking losses are a reminder that the mark of a species in trouble is not rarity, but rate of decline.
Notably, the shifts in abundance of common species can translate into sizeable shifts in ecosystem functioning. One caribou herd (北美驯鹿群), numbering in the hundreds of thousands, removes millions of kilograms of food for animals every year and returns nutrients to the soil in the form of millions of kilograms of animal wastes.
The value of common species is not just ecological and economic, but psychological. Study after study demonstrates that encounters with the natural world improve our mental state. Losing familiar species—whether birds in our backyard or butterflies on our doorstep—is likely to shrink(收缩) such opportunities for engagement.
Rarity will always occupy a significant place in conservation. But in our pursuit for a sustainable and biodiverse future, we must avoid “the extinction of commonness”.
