More than half of UK species have suffered declines in recent years and 15 percent are at risk of vanishing (消失), a report has warned. There is little evidence to suggest the rate of loss is slowing down.

Farming is key to what is happening,with more intensive agriculture affecting nearly half of the species studied and responsible for nearly a quarter of the total impact on wildlife. A loss of mixed farms, changes to sowing patterns,increased use of pesticides and fertilizers and a loss of habitat (栖息地）have taken their toll. The report said government farming policies had led to dramatic changes in farming practices,almost doubling wheat and milk yields since the 1970s, but often at the expense of nature by interrupting the food sources and habitats species rely on.

Climate change is also increasingly affecting UK nature although the impacts are mixed with some species spreading north or surviving better in warmer winters, but others are hit by the loss of coastal habitat, increased sea temperature and wilder weather. In the long term, global warming poses one of the greatest threats to nature around the world. Wildlife is also being hit by urban development, loss of town green areas, changes to the way land and forests are managed and over-abstraction (过度抽取)of water.

“The natural world needs our help as never before,” said naturalist and TV presenter David Attenborough. “We must work together, governments, conservationists, businesses and individuals to help it.”

The good news is that the creation of new wetland by conservation programs and the planting of new woodland, as well as wildlife-friendly farming programs, are providing habitats for struggling species. Reintroduction of species such as the pine marten (松貂)and large blue butterflies is also helping, but more needs to be done, the report said.
