Humans are lazy. We tend towards paths of least resistance. And this is one of the main reasons why I believe more people aren't vegetarian or vegan. It's not really that hard, but it does require a little bit of effort. And that little bit of effort is a big deal for most people.I came up with this thought experiment I call menu roulette. Take the list off all restaurants in the US and pick one at random. Then take the menu of that restaurant and pick an item off it at random. What are the odds that it is vegetarian? or vegan? 10%? 5%? I bet it's less than 1%.
As a product designer, one of the aphorisms I follow is make it easy to do the right thing, and difficult to do the wrong thing. Since eating meat and dairy is bad for your health, the animals, and the environment, it is pretty clearly the wrong thing to do. Yet our whole society is set up to encourage people to do the wrong thing.
So how can we change this? That is the hundred billion dollar question.
You also missing that people just like meat. bad or not for me i have no plan to stop eating it because i enjoy it. stoping would be easy if i wanted to.
