Children have won prizes for imagining what the world will look like in 100 years.

Pupils at Cottesmore St Mary's School, Hove, scooped the gifts of a trip to a laser gun park, to Drusillas Park and board games after coming up with their exotic ideas for the Earth's future.

The winners were Dominic Bentley, eight, Jemima McHugh, ten, and Thomas Watson, nine.

Legal and General sponsored the nationwide competition to encourage children to think about the future and care for the environment.

A spokesman said: "We think all the schools who took part found it an enjoyable and stimulating event."
