SuperEco, an anti-hero

I have an idea for an anti-hero modeled after me--or at least my impulses.  (I don't ALWAYS give in to my impulses.)  SuperEco intervenes every time someone is in danger of harming the environment, so she lands when a person is about to buy meat.  "Don't you realize how many more of the earth's resources it takes to provide meat than to provide vegetables for consumption?  Don't you know we're in a drought?  Haven't you heard of climate change?  Don't you know that every moment in a factory farm is torture for animals?"  You get the idea.  Flying to the rescue and ruining everybody's fun.
