National Geographic and Sky Ocean Ventures have launched a series of challenges for a one-year competition which will focus on reducing single-use plastics.
The prize for the best suggestions in 'The Ocean Plastic Innovation Challenge' is a share of $1.5m (£1.16m) in awards and investment.
It consists of three challenges: to design better packaging, a business model with zero-waste and to design a creative way of showing plastic pollution in a new way.
