Put a sock in it
You may find perfumed socks an indispensable luxury, but Steen Gade, head of the Danish Environmental Protection Agency, thinks they are a pain in the neck. “They undoubtedly add colour to life for some people,” he says, but his agency faces the dilemma of how to regulate thousands of untested chemicals in products that might harm human health or the environment. He believes regulators should apply an “unnecessariness principle”, to dispense with chemicals that “make no difference to how the products work”.
