There's many problems and few solutions, or people willing to actively pursue the solutions that are there. It's on all of us really, but the individual doesn't have the ability to stop commercial fishing, (for instance), so the little people are a bit helpless. However, people could stop eating seafood...that'll render the commercial fishing industry redundant...it'll not happen though.
Humanity is on a fast-track to its own demise. No one wants to make enough changes...when it all comes crashing down I wonder if there'll be anyone left to say, I told you so. Probably not.
You are absolutely right... perhaps there is no one to say that, or few thinking minds. Sad future, isn't it? Maybe we don't see it, but... what about those to come?
