LW: Is there a danger of Whac-a-Mole? Each time an adversary is 'whacked'- it pops up again somewhere else? In short, could focusing on single-use plastics mean that other factors are overlooked- such as overall efficiencies of different materials used for packaging?

VC: It is critical to think about the full impact of any product that we use - from production to consumption to end-of life. Any alternative that comes online should be evaluated for its likely impact. The Ocean Plastic Innovation Challenge judges will assess the feasibility of the teams’ solutions, taking production and market factors into consideration, as well as the likelihood of the solutions’ scalability and their potential impact.
