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.
>It seems the naysayers are doing nothing to try and change the situation
You can thank the naysayers for serious research, otherwise people would just come up with stupid abstract ideas since no one would be skeptical or pessimistic.
I agree with your second point, but I also think we shouldn't rush for a temporary solution that would give people a feeling of "we have at least done something about this, now let's stop worrying about it". Startup culture shouldn't apply to public- or crowd-funded solutions.
