UK to cull badgers to check TB
The UK government is planning to cull badgers, the carriers of bovine tuberculosis (TB). Bovine TB is on the rise in the UK, causing 20,000 cattle to be slaughtered every year. But a 10-year old study of the government's independent scientific group, after a trial cutting of 10,000 badgers, says culling will not help reduce bovine tb. Ecologists say culling could lead to doubling of fox populations, the badgers' natural prey. This could lead to fewer poultry, the prey of foxes. They fear if there is an outbreak of rabies, it could spread quickly since foxes are its carriers.
