I struggle with that sense of responsibility to help others as well and wonder if it is not just a negative state like guilt. Actually we are only responsible for our own actions, thoughts and feelings. In my own life I find people trying to help me feels like people trying to control me and decide what is best for me.So do what you can to help others... but you can't be responsible for everyone else - nope
The flip side of responsibility is to acknowledge that we are part of the problem and we are thus part of the solution. There is no excuse for us to not know what the consequences of our lifestyles and choices are, and we should care. All that is required of us is to do what we can and change what we can. Once we have that mindset then synchronicity will point us in the right direction.
We are all one but we are all different aspects of the source, and greed is an aspect that causes harm to others. Often making healthy choices for ourselves is for the good of all.
What Ernie has said and how he has said it is not going to go away. If we reject his message and choose not to wake up and be open to change, then another Ernie will come along, and another.
