Schools are invited to a new event at the National Maritime Museum in Greenwich before the public gets to see it. The show, Your Ocean, highlights the environmental issues that affect the health of the world’s oceans, and pinpoints key factors in global warming and pollution. It uses a mixture of interactive elements to explain some of the major issues related to conservation and the environment. The show is the final part of the museum’s Planet Ocean drive, a series that also includes Oceans of Discovery and Making Waves. For more details telephone 020 8858 4422; www.nmm.ac.uk
