The Prince of Wales has warned of the “catastrophic” consequences of inaction on issues such as climate change, at a UN sustainability conference in Brazil.
Prince Charles said he had “watched in despair” at the slow pace of progress on the “critical issues of the day,” in a pre-recorded video address in Rio.
He urged world leaders to adopt a more integrated approach to issues such as climate change and food security.
Waiting for the worst to happen would be “too late to act at all”, he said.
Rio+20, the United Nations Conference on Sustainable Development, is attended by heads of state and representatives from governments, non-governmental organisations and the private sector.
In his address, the prince said scientific evidence showed the potential consequences of ignoring the risks.
