Every time I have to buy or use something with unnecessary plastic in it I just feel extreme disgust. There's just too much plastic around us that it would take decades to recycle or decompose them even if we discover the way to do that right now.

First rule of engineering I learnt was: there are always trade-offs. You can't have it both ways. You're right, plastic is cheap, lightweight, resistant, etc. But shouldn't we have asked: "Ok, but what's the catch?"
