Landfill footprint. LMAO!
Go ahead and laugh it up, but I didn't intend it to be a joke.

Climate and environmental issues will NEVER be solved by individual action - yours, mine, or any other Moonbeam Loveearth out there.
To quote the infamous botto... "Correct"

It is large scale game theory and billion-person collusion is not possible when so many people have the same convenience over long-term effects attitude I do.
FIFY

Harsh government policy is the only thing that will work (and I'm in support of it). Until that time, whether I use paper or plastic or throw away a ziplock doesn't make a rat's-***** difference.
So you'd be in favour of having trash police enforcing fines if recycling was made mandatory by law?
You're right about one thing: The single plastic container (or even all the plastic containers you'll throw away in a lifetime) have a minimal impact on the overall scale. When you combine them with everyone else's plastic containers, aluminum cans, EPS packing molds, and all the other junk that everyone doesn't recycle because "what difference does it really make?" it becomes non-biodegradeable mountains of stuff that generations from now, people will have to deal with. But that's not your problem, is it? Just like the impact of CFCs or sub-standard storage of nuclear materials wasn't the problem of much of the generation that generated it, but we're stuck dealing with it now.

The ziplock twist n' lock containers work well, are cheap, and disposable. Use them, love them.
They work well for a little while, which is why they're cheap. Yes, they're disposable and everyone loves stuff that they can just go out and buy a 3-pack of new stuff for $3 when the old ones break... but there are more environmentally responsible choices which can be made.
