I personally try to do my best with not wasting plastic, but I stumbled onto a pretty stupid problem when I tried to use only reusable bags; I needed to buy other plastic bags to throw my garbage away. I couldn't even find any biodegradable plastic bags that was the correct size, so I am kind of stuck to using plastic grocery bags.

I too have that problem. You would think they would make biodegradable garbage bags. I have my fair share of plastic bags and reuse them for instances like smaller trash bags, cat litter box cleaning and dog waste when walking. It is not perfect but reusing them makes it not so wasteful, I think.

I believe one of the major reasons why I'm really advocating a more sustainable future has a lot to do with the fact that I grew up during a time where all children were urged to do beach cleanings, learn about the problems of pollution etc.

This rings true with me. My parents always picked up others trash when we would go on outdoor outings, my dad would take me to the recycling facility with his cans and then give me the money from his cans. At five years knowing I could get money for recycling meant a lot LOL.
