Prior to the 1970s, it was legal to dump refuse such as industrial waste, sewage, and radioactive waste into the ocean. However, during the 1960s, there was a growing awareness about the negative impact of ocean dumping on the marine environment. In 1975, the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, 1972 (known as the London Convention) came into force. The London Convention was the first international regulation to control ocean dumping in order to protect the marine environment from pollution.
