Britain was once covered by thick forests， home to many animals which no longer live here． There were wolves， bears and wild cattle with less than four million people． They lived in small villages protected by wooden walls from the animals outside．

However， all this changed． Now Britain's population has increased to 65 million． Three﹣quarters of Britain consists of fields， towns or cities． Although 25% of land is countryside，new methods of farming mean that there are fewer birds and small animals than ever before． Britain is one of the few countries in the world without a large wild carnivore（食肉动物）．

Some people want to change this． Some say that Britain needs to become more natural again and suggest trees and plants that once grew in Britain should be allowed to grow again． They even say that large wild animals which have not lived in Britain should be helped to return and live wild． They call this " rewilding"．

Not everyone agrees． In the last twenty years， over one million trees have been planted and there are plans for more﹣but wild animals？ Some people ask if wolves will attack sheep or even humans． They are also angry that rewilding might mean an end to walking in the hills many people enjoy． So far， there are no wolves or bears in Britain's forests﹣but soon there might be!
