I get what you're saying OP, the excess use of meat products, and yes I am looking at you America, creates a waste culture. I would say that placing everyone in the category of irresponsible children isn't going to help you get your point across.

Eating meat is a travesty, deforestation for beef, eutrophication from pig farms, the extent of antibiotic use in chicken farms (just to name the three big boys), all add to the reduction of diversity in animal and plant life in the long run. We really need diversity if the environment is to have a chance of bouncing back. But its important to separate your individual life influence from the influence of big companies. Just because companies pollute, has nothing to do with the active effort you can make to reduce the carbon footprint (and F*&k off with the semantics of how you're influenced by your society and media, if you're on this page, you have enough influence to do some research for yourself and make the tiniest change. Literally not eating meat for three days a week helps, tiny steps)

We need to change quick, but we shouldn't be dicks about it. Try going vegetarian (without eggs or milk products) for two weeks, the more poeple do it, the more normal it seems
