Ethical, social and environmental concerns relating to the application of biotechnology in several areas need to be recognized, addressed and regulated adequately by law, said the Padma Bhushan awardee and former director of the Hyderabad-based Centre for Cellular Molecular Biology (CCMB), Pushpa M Bhargava. Delivering his public lecture at the 95th Indian Science Congress here in Visakhapatnam, Bhargava said, ”biotechnology is being applied in at least 32 areas. In some areas it has created wonders, but there are genuine concerns which need to be addressed.”
