what is obvious is that we are all in this thing together, whether we like it or not. earth [the world we live in] is a closed-loop system- what happens on earth stays on earth. when we put out bad stuff, it has no choice but to go 'round and 'round until it eventually comes back to the sender. our world is becoming full of bad stuff.
humanity has been given a chance to love one another, and the lion's share of us are just saying "nah, that's not for me". one can say " i am SO an island!" or "i am a rock, i am an island"- one might as well say "i am NOT my brother's keeper" - [this seems to be a popular statement nowadays]. but that is just whistling past the graveyard. of course we are all born alone and die alone- but we have to GROW beyond the path of least resistance, or get stuck in a rut. one CAN learn to love in some manner, even if one doesn't receive love or never received love. the choice is between warm fuzzies or cold pricklies, and most of humanity has chosen to be part of the problem rather than part of the solution.
