To say that it is not our fault does not relieve us of responsibility... we may not have polluted the air, but we need to take responsibility, along with others, for cleaning it up. Each of us needs to look at our own behavior. Am I perpetuating and reinforcing the negative messages so pervasive in our culture, or am I seeking to challenge them?
Time is not a line but a dimension, like the dimensions of space. If you can bend space you bend time also, and if you knew enough and could move faster than light, you could travel backward in time and exist in two places at once.
