I don't know enough about the subject to have the pretence to judge whether it can work, what I do know is that: 1. It seems the naysayers are doing nothing to try and change the situation, but then again, history books aren't populated with names of critics... 2. A partial solution is better than no solution. It doesn't solve the problem of microscopic plastic parts ? So what ? It also doesn't solve world hunger and global warming, but having more people with the attitude and vision of this young entrepreneur just might.
