not obvious to people that something is seriously wrong

We each answer for ourselves. And once we do answer the call to wake up we take action. That's the only rational response. We'll tell others like there's no tomorrow, because there may not be one if we don't. We take appropriate action in our own lives first and move to prepare our loved ones for what may be immediate consequences of what we've realized is going on and how to avoid or mitigate it. We change our eating and buying habits, we re-evaluate our livelihood, personal attachments and living conditions.

All the while intelligently yet passionately sharing what we've discovered to be true and the possible consequences.

That's called waking up. And it's not comfortable. It's a lot of hard work, and takes a lot of courage. But really we're only acting in a responsible manner when we do so, simply doing what's right. It's not that big of a deal - unless our priority is how we appear to others, and keeping old patterns of behavior and possessions that we call "comforts".

Ignoring the blatantly obvious...
