New Delhi : Holding that protecting wildlife is the constitutional duty of the Centre and states, the Supreme Court has directed Chhattisgarh to forthwith take measures to protect endangered Asian wild buffaloes and to ensure they are not subjected to inter-breeding so that their genetic purity is preserved. "All effective steps should be taken by the state to protect the Asian wild buffalo (Bubalus bubalis) which is declared as a state animal by Chhattisgarh. "The state would also take immediate steps to ensure that inter-breeding between wild and domestic buffaloes does not take place and the genetic purity of the wild species is maintained," the apex court said in a judgement. A special forest bench of justices K S Radhakrishnan and C K Prasad gave the ruling on amicus curiae and counsel P S Narasimha's application for preserving the endangered wildlife species. Quoting Article 51 A(g) of the Constitution, the apex court said it is the duty of every citizen of India to protect and improve the natural environment, including the wildlife, and to have compassion for living creatures.
