I personally don't feel that my diet has enough of an impact on food production to warrant the inconvenience and discomfort that would come with a vegan lifestyle.
On average, one more person buying an easily-produced resource results in the production of an estra personsworth of that resource. The large numbers of other people mainly just make it harder to feel, since the human brain sucks at large numbers.
I disagree.
Under the assumption that I am a recluse and have zero capacity to influence anyone else on dietary choices, my ability to affect animal welfare through buying choices is strongly quantized. Purchasing a burger at a busy restaurant in a large city will not affect how many burgers they purchase from their distributor. Assuming they buy by the case (what restaurant wouldn't?), affecting how much they purchase would require either eating there extremely often or being part of a large group of people that eat there, all of which cease buying burgers...
Just a thought I had the other day; what do you think that the political ideas of conservatism have to do with cognitive bias? I mean, how much are people willing to change naturally, without arguing any points?
I know very little about all of these things, so forgive me if this is a silly thought.
