A team of farmers, university researchers and environmentalists is busy at work in the wetlands of eastern England. They are digging into the area’s wheat fields, looking for wet earth that could hide lost ponds underneath. It takes the group of diggers just a few hours to revive (使复活) one dying pond. It’s near Hindolveston, a thousand-year-old village close to the North Sea.

“As soon as the buried ponds get water and light, they just spring to life,” says Nick Anema, a farmer in nearby Dereham. He’s brought seven ponds on his farm back to life. “Frogs and all the insects like dragonflies can be seen here again,” he said.

But the battle for the wetlands is a struggle. While efforts to stop losses are continuing, wetlands around the world are still being filled in and covered up. Over the past three centuries, almost 90% of the world’s wetlands have disappeared. The loss rate has increased since the 1970s, with wetlands now disappearing three times faster than, the world’s forests.

Some 5,000 wetland-dependent animal species could die out because of such losses. Wetland loss can also affect human beings. Wetlands act as natural storage areas for water. Losing those areas could lead to more severe flooding in many parts of the world. And the act of removing water from wetlands can release huge amounts of carbon dioxide, a major contributor to climate change.

Human-made wetlands, however, aren’t decreasing in number. Rice fields, water reservoirs and agricultural stock ponds have all increased since the 1970s. Yet scientists are concerned about this phenomenon. “People brag (自夸) about the fact that there’s been no net loss (净损失) of wetlands. But what they’ve done is destroy natural wetlands and create artificial ones,” says Stuart Pimm, a Duke University professor. “It makes it look like you’re doing no harm when the reality is very different.”

一个由农民、大学研究人员和环保主义者组成的团队正在英格兰东部的湿地忙于工作。他们正在该地区的麦田里挖掘，寻找潮湿的土地，以隐藏下面丢失的池塘。这群挖掘者只需要几个小时就能复活(使复活) 一个垂死的池塘。它靠近Hindolveston，一个靠近北海的有着千年历史的村庄。

附近Dereham的农民Nick Anema说：“一旦被掩埋的池塘得到水和光，它们就会苏醒过来。”。他让农场里的七个池塘复活了。他说：“青蛙和所有像蜻蜓一样的昆虫在这里都能再次看到。”。

但湿地之争是一场斗争。尽管阻止损失的努力仍在继续，但世界各地的湿地仍在被填满和覆盖。在过去的三个世纪里，世界上几乎90%的湿地已经消失。自20世纪70年代以来，湿地的消失速度一直在增加，是世界森林消失速度的三倍。

大约5000种依赖湿地的动物物种可能会因为这些损失而灭绝。湿地的丧失也会影响人类。湿地是水的天然储存区。失去这些地区可能会导致世界许多地区发生更严重的洪水。从湿地中取水的行为会释放出大量的二氧化碳，这是气候变化的主要原因。

然而，人造湿地的数量并没有减少。自20世纪70年代以来，稻田、水库和农业贮水池都有所增加。然而，科学家们对这一现象感到担忧。“人们吹嘘(自夸) 关于没有净损失的事实(净损失) 湿地。但他们所做的是破坏自然湿地，创造人工湿地，”杜克大学教授斯图尔特·皮姆说。“当现实情况大不相同时，这会让人觉得你没有造成伤害。”
