On a related note, I often find that I don't know what to do if I want to help enact change at a level that's too far removed or high above me.

There are a number of factors at play here:

Sometimes, I'm not aware of the issue

I don't know if the offending party is amenable at any level to changing their mind

I don't know if something is possibly against the law (e.g. I didn't know the AG had a say until I say this post)

I don't know if the authorities or avenues of dissent that I have access to have any jurisdiction over or effect on the offending party

I often have very little insight into how others feel about the issue.

I don't know how much work needs to be done to shift proceedings (e.g. how many people need to contact the AG for them to change their priorities)

I don't know at what level I need to focus my efforts on (e.g. community, corporate, federal, ngo, etc.)

Everything is scattered all around the place.

For example, I saw this good idea in another HN post: "Would it be so hard to use less packaging on foods, especially snacks?". I have an opinion on this, but I don't know how to effectively voice it.

Is there an existing system, or can we make a better system to most effectively turn our opinions on the matter into action?
