New Zealand government has decided to kill more than one lakh cows. Reason! It was trying to eradicate a disease-causing bacteria from the species. Cows will be killed if the said bacteria is found in their blood... even if they look healthy! New Zealand is home to some 10 million cows, about double of its population and milk stands to be the single largest export of the country. However, recently its milk production has been hit by a disease named Mycoplasma bovis.. which has led the government to take such a strict action.
