Who makes up these words?

Freeganism is an anti-consumerist lifestyle whereby people employ alternative living strategies based on "limited participation in the conventional economy and minimal consumption of resources". (Sounds like an unemployed, homeless or psychotic person to me.) Many freegans get free food by pulling it out of the trash, a practice commonly nicknamed dumpster diving. (again, I refer to above bracketed thought) Freegans find food in the garbage of restaurants, grocery stores, and other food related industries, which they claim allows them to avoid spending money on products that exploit the world's resources, (?? huh ??) contribute to urban sprawl, treat workers unfairly, or disregard animal rights. By foraging, they believe they are keeping perfectly edible food from adding to landfill clutter and that can instead, feed people and animals who might otherwise go hungry. Maybe I'll see what my local Von's is throwing away before I actually go inside and buy something next time and avoid exploiting the world's resources. Obviously, it must have it's merits or freeganism would not be around....
